hi all more bad news with this coronavirus

Global Alert and Response (GAR)

Novel coronavirus infection - update

21 February 2013 - The Ministry of Health in Saudi Arabia has informed WHO of another confirmed case of infection with the novel coronavirus (NCoV).

The patient was hospitalized on 29 January 2013 and died on 10 February 2013. The case was laboratory-confirmed on 18 February 2013. Further investigation into this case is ongoing.

In the United Kingdom, the Health Protection Agency continues to investigate the family cluster where three members of the family tested positive for NCoV infection. One member of this family, who had an underlying health condition, has died.

To date, WHO has been informed of a total of 13 confirmed cases of human infection with NCoV, including seven deaths.

Based on the current situation and available information, WHO encourages all Member States (MS) to continue their surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns. Testing for the NCoV should be considered in patients with unexplained pneumonias, or in patients with unexplained, severe, progressive or complicated respiratory illness not responding to treatment, particularly in persons traveling from or resident in areas of the world known to be affected.

Any clusters of SARI or SARI in healthcare workers should be thoroughly investigated, regardless of where in the world they occur.

All MS are reminded to promptly assess and notify WHO of any new case or clusters of cases with NCoV infection.

WHO does not advise special screening at points of entry with regard to this event nor does it recommend that any travel or trade restrictions be applied.

WHO continues to closely monitor the situation.

Novel coronavirus infection - update

6 March 2013 - The Ministry of Health in Saudi Arabia has informed WHO of a new confirmed case of infection with the novel coronavirus (NCoV).

The patient, a 69-year-old male, was hospitalized on 10 February 2013 and died on 19 February 2013. Preliminary investigation indicated that the patient had no contact with previously reported cases of NCoV infection and did not have recent history of travel.

To date, WHO has been informed of a global total of 14 confirmed cases of human infection with NCoV, including eight deaths. Of the total number, seven cases, including five deaths, have been reported from Saudi Arabia.

Based on the current situation and available information, WHO encourages all Member States (MS) to continue their surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns. WHO is currently working with international experts and countries where cases have been reported to assess the situation and review recommendations for surveillance and monitoring.

All MS are reminded to promptly assess and notify WHO of any new case of infection with NCoV along with information about potential exposures that may have resulted in infection and a description of the clinical course.

WHO does not advise special screening at points of entry with regard to this event nor does it recommend that any travel or trade restrictions be applied.

WHO continues to closely monitor the situation.

  • The CDC is warning state and local health officials about potential deadly infections from never-before-seen virus
  • CDC says people who develop a severe lower respiratory illness within 10 days of returning from the Middle East should be evaluated
  • Health officials are also issuing warnings about antibiotic-resistant bugs hitting U.S. hospitals
 

By Daily Mail Reporter and Reuters Reporter

PUBLISHED: 06:43 GMT, 8 March 2013 | UPDATED: 09:59 GMT, 8 March 2013

The Centers for Disease Control and Prevention on Thursday warned state and local health officials about potential infections from a deadly virus previously unseen in humans that has now sickened 14 people and killed 8.

Most of the infections have occurred in the Middle East, but a new analysis of three confirmed infections in Britain suggests the virus can pass from person to person rather than from animal to humans, the CDC said in its Weekly Morbidity and Mortality Report on Thursday.

The virus is a coronavirus, part of the same family of viruses as the common cold and the deadly outbreak of Severe Acute Respiratory Syndrome (SARS) that first emerged in Asia in 2003. The new virus is not the same as SARS, but like the SARS virus, it is similar to those found in bats.

Spread: At the same time, the CDC is also issuing warnings about the spread of 'superbugs' in U.S. hospitals that are resistant to antibiotics

So far, no cases have been reported in the United States.

According to the CDC's analysis, the infections in Britain started with a 60-year-old man who had recently traveled to Pakistan and Saudi Arabia and developed a respiratory illness on January 24, 2013. Samples from the man showed he was infected with both the new virus and with H1N1, or swine flu.

The infection that is believed to be coming from the Middle East were found in Britain after a 60-year-old man who had recently traveled to Pakistan and Saudi Arabia and developed a respiratory illness on January 24, 2013. Samples from the man showed he was infected with both the new virus and with H1N1, or swine flu.

 

This man subsequently passed the infection to two members of his household: a male with an underlying illness who became ill on February 6 and subsequently died; and a healthy adult female in his household who developed a respiratory illness on February 5, but who did not need to be hospitalized and has recovered.

The CDC said people who develop a severe acute lower respiratory illness within 10 days of returning from the Arabian Peninsula or neighboring countries should continue to be evaluated according to current guidelines.

The health agency said doctors should be watchful of patients who develop an unexplained respiratory infection within 10 days of traveling from the Arabian Peninsula or neighboring countries.
Symptoms of infection with this new virus include severe acute respiratory illness with fever, cough and shortness of breath. Neither the CDC nor the World Health Organization has issued travel restrictions related to the virus.

Weakening: Many antibiotics are now unable to kill the resistant strains of bacteria

Warnings of the deadly virus come as the CDC announced concerns over an increasing number of infections from a 'nightmare bacteria' found in U.S. hospitals.

Public health officials have warned that in a growing number of cases existing antibiotics do not work against the superbug, Carbapenem-Resistant Enterobacteriaceae (CRE).

Patients became infected with the bacteria in nearly four per cent of US hospitals and in almost 18 per cent of specialist medical facilities in the first half of 2012, according to the Centers for Disease Control and Prevention (CDC).

Dr Tom Frieden, director of the CDC, said in a statement that the strongest antibiotics 'don't work and patients are left with potentially untreatable infections.'

He said scientists were 'raising the alarm' over the problem following increasing concern.

Increasing numbers of patients in US hospitals have become infected with CRE, which kills up to half of patients who get bloodstream infections from them, according to a new CDC report.

Some of the more than 70 types of Enterobacteriaceae bacteria - including E-coli - have become gradually resistant over a long period of time, even to so-called, 'last resort drugs' called carbapenem.

During the last 10 years, the percentage of Enterobacteriaceae that are resistant to these last-ditch antibiotics rose by 400 percent. One type of CRE has increased by a factor of seven over the last decade, Fox News reports.

CRE infections usually affect patients being treated for serious conditions in hospitals, long-term acute-care facilities and nursing homes. Many of these people will use catheters or ventilators as part of their treatment - which are thought to be used by bacteria to enter deep into the patient's body

Birmingham grandad is UK's second Coronavirus victim

Abid Hussain, of Winson Green, lost battle against Sars-like bug in hospital on Tuesday

Birmingham%20grandfather%20Abid%20Hussain Birmingham grandfather Abid Hussain

Birmingham grandad Abid Hussain has become the UKโ€™s second victim to the new Sars-like bug Coronavirus.

The tragedy comes as Mr Hussainโ€™s wife and daughter were in Pakistan after burying his son Khalid, 38, who had also fallen victim to the killer disease.

The dad-of-two, in his 60s, of Winson Green, was being treated at Wythenshawe Hospital, in Manchester, and seemed to be improving.

But he took a turn for the worse and lost his battle on Tuesday.

His funeral was held at a mosque in Small Heath, on Wednesday and his body has now been taken to Pakistan for burial.

Close friend Abdul Rashid, 60, had known Mr Hussain for more than 20 years and described him as a โ€œwise and gentle manโ€.

He said: โ€œI am very upset that he has died. It is a great shock to the family and the community. His wife and daughter were still in Pakistan dealing with the sonโ€™s burial and were planning to come back when Abid died.

โ€œIt was a shock to discover he was suffering from this terrible disease when he came back from Mecca. His daughter had gone out there with him, but was given the all clear.โ€

Mr Hussain had contracted the disease after a trip to Saudi Arabia with his daughter. He complained of a temperature and chest problems to his friend Abdul upon his return at the end of January and within a few days he was admitted to City Hospital, in Birmingham.

Itโ€™s thought during this period that his son, dad-of-two Khalid, suffering from cancer, picked up the bug from his father.

Khalid was undergoing chemotherapy at the Queen Elizabeth Hospital, in Edgbaston. He continued to be treated there for both conditions and sadly died on February 17.

Itโ€™s thought Mr Hussain never knew that his son had passed away.

Abdul explained: โ€œI spoke with Abid on the phone two days after he came back from Saudi Arabia. He was complaining of a temperature and chest problems. I told him to go and see the doctor, and then said I would speak to him again afterwards.

โ€œBut I didnโ€™t get to as he was admitted to hospital. I went to see him but he was unconscious.

โ€œIt was a few days later that the hospital realised what was wrong and he was transferred to the hospital in Manchester for specialist care. I was kept updated on his condition and went to see him there.โ€

And he paid tribute to his friend: โ€œAbid was a very wise man who had an extremely gentle personality. Weโ€™d been friends for more than 20 years and we knew each other through family. His son Khalid also lived in Birmingham before moving to Rotherham.โ€

The first patients infected with the coronavirus fell ill in Jordan, Qatar and Saudi Arabia last year, but the source of the infection remains unknown, despite missions by the World Health Organisation and other international groups. As with Sars, the virus has most likely jumped from bats into other animals, in this case perhaps goats or other livestock, which have gone on to infect humans.

It has infected at least 15 people since it emerged in the Middle East last year โ€“ more than half of whom have died of pneumonia and multiple organ failure, symptoms that were common in Sars patients.

A Wythenshawe Hospital spokesman confirmed Mr Hussain had died on Tuesday

The World Health Organization says there has been another infection with the new coronavirus, this time in someone who was a contact of an earlier case.

But the Geneva-based global health agency says it doesn't have enough information to estimate whether the new infection was the result of person-to-person spread.

The case is from Saudi Arabia, the ninth from that country.

Globally there have now been 16 confirmed infections from the new virus -- which is from the same family as SARS -- with at least nine deaths.

The WHO statement says the newest case was a contact of a 39-year-old Saudi man who died from the infection on March 2.

The newest case is a person who had mild illness only; the person has recovered and has been released from hospital.

The WHO says currently it doesn't know enough to gauge whether the new case was infected by the 39-year-old man, or contracted the virus from the same source as he did.

In fact, it appears that the WHO may know very little about the new case.

The press release from the agency does not reveal the individual's gender or age. Nor does it say when the person fell ill, was hospitalized and released from hospital.

WHO press releases announcing infections with the new coronavirus -- which it calls NCoV -- generally contain those kinds of details when the health agency has them.

If it turns out this is a case of person-to-person spread, it would not be the first time that has been seen.

There have been at least three instances where human-to-human spread is suspected, and in one of those cases it is assumed to have happened.

That instance involved a cluster of cases in Britain, started by a man who returned home ill after a trip to Pakistan and Saudi Arabia. The man's son, who had cancer, became infected and died. Another member of their extended family was infected, but she had only mild illness.

As the son and the third case in that cluster had not travelled outside Britain before becoming ill, it is believed they contracted the virus from the man who had travelled.

A British newspaper, the Birmingham Mail, reported Saturday that the first case in that cluster succumbed to his illness this week. But the WHO's statement Saturday does not reflect an additional death caused by the coronavirus.

The new virus was first spotted last June after a man from the Saudi capital, Riyadh, died from an infection for which a cause could not initially be discovered.

Subsequently it was recognized that earlier cases had occurred in Jordan, where 11 people fell ill last April in a cluster of mysterious infections in a hospital. Stored samples from the two fatal cases in that cluster later revealed they had been infected with the coronavirus.

When a blood test to determine past infection becomes available, it may be possible to determine if others in that cluster were also infected. But to date laboratories working to develop a blood test that picks up these cases has proved difficult to develop.

To date four countries have recorded infections: Saudi Arabia, with nine cases and six deaths; Qatar, with two cases; Britain, with three cases and one (or two) deaths; and Jordan, with two fatal cases.

hi all,this is a bit scary given they must be on high  alert to put this girl in isolation on arrival in  HONG KONG


  A four-year-old girl visiting from Qatar has been isolated after she tested negative for a deadly Sars-like virus yesterday.

The girl had initially sparked fears that the novel coronavirus had reached Hong Kong after she showed signs of carrying the virus that has killed at least nine people around the world.

She was instead found to be carrying the less dangerous adenovirus, a member of the cold virus family.

Nevertheless, health officials warned Hongkongers to stay vigilant against the new virus.

Last night, rapid tests were carried out on the girl from the Philippines who had previously travelled to Qatar with her parents. The 16 reported cases of novel coronavirus are mainly in the Middle East.

The child first displayed symptoms on Friday and was sent to a private clinic. She was then transferred to Queen Mary Hospital in Pok Fu Lam with a fever and a headache.

She was now in a stable condition, Secretary for Food and Health Dr Ko Wing-man said.

Most adenovirus infections are mild and require no therapy or treatment of the flu-like symptoms. Deaths are exceedingly rare.

Ko said the World Health Organisation had just informed the city of a 16th case of novel coronavirus, which causes severe respiratory disease. The patient, based in the Middle East, was a contact of the 15th case, which the WHO reported on March 12.

"I have to renew our appeal to all Hong Kong people to remain vigilant and adopt good personal hygiene practices and a healthy lifestyle," Ko said on the sidelines of a 2013 World Tuberculosis Day awareness event.

Reports of the first cases of the novel coronavirus in Europe caused panic in Hong Kong, as memories were revived of the severe acute respiratory syndrome outbreak in 2003.

The Sars virus, which plunged the city into turmoil and eventually killed 299 people in Hong Kong, arrived via an infected tourist. The epidemic prompted officials to overhaul hospital and immigration procedures aimed at guarding against viral transmissions.

According to the WHO, the novel coronavirus has killed nine out of the 16 people who were infected, meaning its death rate could be higher than 50 per cent.

Germany, Saudi Arabia report new novel coronavirus cases

Lisa Schnirring * Staff Writer

Mar 25, 2013 (CIDRAP News) โ€“ The German media and Saudi Arabia's health ministry have reported two new novel coronavirus (NCoV) cases, one in a patient hospitalized in Munich and the other a mild illness in a Saudi Arabian resident.

According to an early report today in German from Abendzeitung, a news source based in Munich, the German patient arrived in Germany from the Middle East by medical transport. It says the patient is in isolation in the intensive care unit (ICU) at Munich Municipal Hospital.

The patient is a 73-year-old man from the United Arab Emirates who was first treated in an Abu Dhabi hospital on Mar 19, another German news source, TZ Online, reported today. It said medical authorities are monitoring about 50 people who had contact with the patient.

The case appears to be Germany's second NCoV case. In October a Qatari man was hospitalized and treated in Germany but has since recovered. The man's NCoV infection wasn't detected until almost a month after he was hospitalized, and so far no evidence of infection has been found in any of that case-patient's German contacts.

Saudi Arabia's health ministry said its new case is a contact of a 39-year-old man who died in early March from the disease in that country, according to a Mar 23 World Health Organization (WHO) statement. The patient had a mild illness, recovered, and has been discharged from the hospital. It said there isn't enough information to allow a conclusive assessment of the mode and source of transmission.

The WHO provided no other details about the patient's NCoV infection. However, Ziad Al-Memish, undersecretary with the health ministry, said the patient is from Riyadh, Arab News, an English-language newspaper based in Jeddah, reported yesterday. He added that the ministry has taken prevention measures and is monitoring the disease.

The latest infection in Saudi Arabia  appears to represent yet another instance of a mild illness in a person who had contact with another infected patient. Though the disease has been fatal for many patients infected with NCoV, the emergence of mild cases has raised questions about surveillance for the disease and whether people with asymptomatic or mild disease could be playing a role in the spread of the virus.

In a related development, the index patient in a recent three-case British family cluster has died, according to a Mar 23 Birmingham Mail report. The man died at Wythenshawe Hospital in Manchester on Mar 19, and his body has been taken to Pakistan for burial. The 60-year-old man got sick at the end of January after traveling to Pakistan and Saudi Arabia and has remained hospitalized.

The Saudi Arabian case pushes the number of WHO-confirmed NCoV cases to 16, and the UK death raises the fatality count to 10. That count does not include Germany's new case.

The second patient sickened in the UK family cluster was a 38-year-old male household contact who died on Feb 17. The Birmingham Mail report said he was the older man's son. The third patient is a 30-year-old woman from a different household who got sick with a mild NCoV infection after visiting the older man three times in the hospital.

Two other clusters have been reported among the NCoV cases, but few details are known. One involved three members of one Saudi family and the other included two Jordanian deaths that were part of a cluster linked to a hospital ICU.

In other coronavirus developments, though NCoV doesn't appear to spread easily from person-to-person so far, some infectious disease experts aren't ruling out the possibility that "superspreaders" could contract the virus and contribute to a more global outbreak, much the way SARS (severe acute respiratory syndrome) spread 10 years ago, the Canadian Press (CP) reported today.

Ron Fouchier, PhD, told the CP that the current transmission patter could change quickly if an NCoV superspreader were hospitalized in a facility that didn't recognize the disease and take precautions. The CP story noted that during the SARS epidemic only a few people infected a fair number more, which uncovered the disease and sparked global panic.

Donald Low, MD, a microbiologist from Toronto who played a key role in Canada's response to SARS, told the CP that it's impossible to predict the spread of NCoV, because coronaviruses are RNA viruses, which are known for mutating rapidly.

UAE man dies from novel coronavirus in Germany

Lisa Schnirring * Staff Writer

Mar 26, 2013 (CIDRAP News) โ€“ A man from the United Arab Emirates (UAE) hospitalized in Germany with a novel coronavirus (NCoV) infection died today, according to reports from German health officials and the World Health Organization (WHO).

Germany's Robert Koch Institute (RKI) said in a statement in German that the man died today from a severe infection. He had an underlying illness and was on a ventilator when he was flown to Munich and hospitalized on Mar 19 and diagnosed with an NCoV infection on Mar 23. The RKI also said lab tests revealed other respiratory pathogens, but it did not say which ones.

The World Health Organization (WHO) today confirmed the patient's NCoV infection and death, noting that he was a 73-year-old man who had been transferred by air ambulance from a hospital in Abu Dhabi to Munich.

In its statement the WHO also confirmed the death of a British man who was the index patient in a recent family case cluster of NCoV infections. The latest developments push the global number of confirmed NCoV cases to 17, including 11 deaths.

The WHO said it is working with experts and countries that have reported cases to assess the situation and review recommendations for surveillance and reporting. It reminded countries to promptly report any new NCoV cases, including information about potential exposures and a description of the clinical course.

WHO's statement included no other information about the cases, but new details about German's latest imported case were included in some media reports. According to a report in German today from Bild, a newspaper based in Berlin, the man died of "circulatory shock" at Munich Municipal Hospital. It said the man was a member of the ruling family of Dubai and got sick after going to a camel race.

The RKI said the identification of a second imported NCoV case in Germany doesn't increase the risk to the general population, because so far there is no evidence of sustained human-to-human transmission.

Global health officials have not determined how the virus spreads to humans, but genetic sequencing studies have suggested that the new virus is most closely related to bat coronaviruses.

So far all countries linked to the infections are in the Middle East: Jordan, Qatar, Saudi Arabia, and the UAE. Two of the patients in the three-person British family cluster did not have a recent travel history, but they did have contact with the index patient, who had recently traveled to Pakistan and Saudi Arabia.

The US Centers for Disease Control and Prevention (CDC) said in an update today that NCoV symptoms include fever, cough, and shortness of breath. It said NCoV isn't like any other coronavirus that has infected humans before, including SARS (severe acute respiratory syndrome). However, it added that, like SARS, NCoV is most similar to coronaviruses found in bats.

Investigators are trying to determine the source of the virus and how it spreads, the CDC said. It added that coronaviruses usually infect only one species or a small number of related species. However, the CDC noted that the SARS coronavirus can infect a range of people and animals, including monkeys, Himalayan palm civets, raccoon dogs, cats, dogs, and rodents.

So far no infections have been reported in the United States, and no travel warnings have been posted for any countries.

The mysterious new coronavirus that emerged in the Middle East and has killed 11 people is potentially more deadly than Sars and also more "promiscuous" - able to infect many different species - University of Hong Kong research has found.

Unlike Sars (severe acute respiratory syndrome), the new coronavirus can affect many different organs in the body and kills cells rapidly, the researchers say.

The source of the new infection is still unknown, but the virus appears to have originated in bats, a team of European experts wrote in the journal mBio.

The HKU research listed animals including monkeys, pigs, civet cats and even rabbits that could be hosts of the virus before it found its way to humans. Lead researcher Yuen Kwok-yung, a microbiologist, said this meant the source of human infection would be difficult to trace.

The World Health Organisation announced yesterday that the disease had killed two more people - a 73-year-old from the United Arab Emirates and a Briton who had visited Saudi Arabia and Pakistan - bringing the death toll to 11. The WHO has confirmed 17 cases to date.

Yuen told the South China Morning Post that the virus could cause a deadly pandemic if it mutated further. "It could be more virulent [than Sars]", he said. "The Sars coronavirus infects very few human cell lines. But this new virus can infect many types of human cell lines, and kill cells rapidly."

The findings, tested in human cell lines, suggest the virus could cause widespread organ infection. It could attack the lower airway, liver, kidneys and intestines as well as tissue macrophages - cell clusters that "eat" bodily debris such as dead cells.

The report, published by the Journal of Infectious Diseases this week, says the new virus "is markedly different" from the other non-Sars human coronaviruses that usually have little ability to move among different cells, and cause self-limiting upper respiratory tract infections.

This may explain why patients with the new coronavirus can suffer multiple organ failure, resulting in a high mortality rate of 56 per cent - in contrast to 11 per cent for Sars.

Yuen said: "The Sars coronavirus infected very few animal cell lines. It was finally traced to bats and civets. But we may have a very hard time, as this new virus seems to be much more promiscuous."

Yuen said, however, that the new virus did not appear to be very infectious, as it tended to infect lower respiratory cells instead of upper respiratory ones like Sars, but this pattern might change as the virus mutated.

"We still have a lot to do before we can learn more about this virus," Yuen said. "Cell line cultures and even animal models may not completely reflect what [it] can do to humans. But this is certainly another step forward."

The Health Department yesterday held a "desktop drill" to test the government's preparedness for a possible outbreak of novel coronavirus.

Hong Kong prepares for new coronavirus

  •  0 1 1 14

By Keith Bradsher

New York Times

HONG KONG โ€”

A decade after severe acute respiratory syndrome swept through Hong Kong and then around the world, the city is among the first to become worried about the emergence and spread of another, genetically related virus in the Middle East.

Medical researchers emphasize that they do not know if the new virus, which has killed 11 of the 17 people infected, will develop the same ability as SARS to spread from person to person. The World Health Organization is taking a cautious stance, stopping short of urging any special measures.

But Hong Kong is already taking preventive measures. Without a single confirmed human case of the new virus in East Asia so far, the government of the autonomous Chinese territory has begun alerting and training employees at hospitals, clinics and the airport to identify possible cases. Wide-ranging medical research is already under way.

Senior government officials held an extensive exercise last week to simulate the oversight of the quarantine and treatment of patients and their associates if a single person infected with the new virus arrived at the Hong Kong airport and began spreading it. The Health Department announced that it would โ€œstay vigilant and continue to work closely with the WHO and other overseas health authorities to monitor the latest development of this novel infectious disease.โ€

The Hong Kong governmentโ€™s measures reflect a continued preoccupation with public health โ€” some say an obsession โ€” that came about after nearly 1,800 people in Hong Kong became extremely ill with SARS in a few weeks during spring 2003, with 299 of them dying.

โ€œAt the moment, I think Hong Kong is likely to be the one with the strongest border control against this new virus for obvious historical reasons,โ€ said Dr. Yuen Kwok-yung, chairman of the infectious diseases section of the microbiology department at Hong Kong University.

Some health experts in the West have been wary of drawing too much attention to the new virus, which is a coronavirus like SARS. They point out that as researchers have begun looking harder for coronaviruses after the SARS outbreak, they have found more of them.

Much of the research has been done in Hong Kong, which became a leading center for disease research as a British colony before the handover to China in 1997. The World Health Organization has long sent samples from all over Asia to Hong Kong University for testing, and Yuen and his colleagues at the university played a central role in identifying the SARS virus in 2003.

Hong Kong University researchers are now expressing growing concern about the new coronavirus that has emerged in the Middle East, known as novel coronavirus. Dr. Malik Peiris, a co-discoverer of SARS who is the director of the center for influenza research at Hong Kong University, warned that while SARS faded away after a year, with 8,445 cases and 790 deaths worldwide, two other coronaviruses had jumped from animals to people in the past two centuries and become endemic.

One of the concerns about the novel coronavirus is that it seems deadlier, having killed more than half of the people with confirmed cases. A study published last week in The Journal of Infectious Diseases by Yuen and 12 colleagues in Hong Kong and mainland China found that the new virus also infects a wide range of human tissue types than the SARS virus and kills them more quickly.

One big question is whether far more people are being infected without detection, in which case the disease may kill a lower percentage of victims but also be more transmissible. Yuen said that when 2,400 people were screened recently in Saudi Arabia for antibodies to the virus, none had them.

That suggests that the virus is periodically infecting people from an unknown animal host, but has not developed the ability to pass easily from person to person, he said.

The H5N1 avian influenza virus has been periodically jumping from birds to people and causing sporadic deaths for 16 years without developing sustained transmissibility among people. On the other hand, the SARS virus appears to have developed transmissibility after only a few months of sporadic infections of people in southern China in late 2002.

For the new virus, โ€œwe may be at the 2002 situation at this time, and that would be very, very bad,โ€ Yuen said.

WHO confirms 15th case of deadly new virus in Saudi Arabia



By Kate Kelland

LONDON | Tue Mar 12, 2013 8:51pm EDT

(Reuters) - A Saudi man infected with a deadly new virus from the same family as SARS has died, becoming the ninth patient in the world to be killed the disease which has so far infected 15, the World Health Organization said on Tuesday.

The 39-year-old developed symptoms of the novel coronavirus (NCoV) on February 24 and died on March 2, several days after being hospitalized, the WHO said in a disease outbreak update

NCoV is from the same family ofviruses as those that cause common colds and the one that caused the deadly outbreak of Severe Acute Respiratory Syndrome (SARS) that first emerged in Asia in 2003. The new virus is not the same as SARS, but similar to it and also to other coronaviruses found in bats.

The WHO first issued an international alert in September after the virus infected a Qatari man in Britain who had recently been in Saudi Arabia.

Symptoms of NCoV include severe respiratory illness, fever, coughing and breathing difficulties.

"Preliminary investigation indicated that the (latest Saudi)patient had no contact with previously reported cases of NCoV infection," the WHO said. "Other potential exposures are under investigation."

Nine of the 15 people confirmed to have been infected with NCoV have died. Most cases have been in the Middle East or in patients who had recently traveled there.

Research by scientists in Europe has found that NCoV is well adapted to infecting humans and may be treatable with medicines similar to the ones used for SARS, which killed a tenth of the 8,000 people it infected.

The Geneva-based WHO said it was monitoring the situation closely and urged its member states to continue surveillance for severe acute respiratory infections and to carefully review any unusual patterns.

"WHO is currently working with international experts and countries where cases have been reported to assess the situation and review recommendations for surveillance and monitoring," it said, adding that national authorities should "promptly assess and notify" it of any new NCoV cases.

A new and deadly virus that has killed 11 of the 17 patients treated for it in the Middle East and Britain appears to cause an infection deep in the lungs, researchers said.

Washington - A new and deadly virus that has killed 11 of the 17 patients treated for it in the Middle East and Britain appears to cause an infection deep in the lungs, researchers said on Wednesday.

Six research monkeys infected with novel human coronavirus were found to quickly develop pneumonia, according to a letter by National Institutes of Health experts in the New England Journal of Medicine.

After being exposed to samples of the virus, the rhesus macaques fell ill within 24 hours, with symptoms including elevated temperature, lack of appetite, coughing and fast breathing.

The macaques' illnesses appeared to last a few days before clinical symptoms went away. After euthanizing the monkeys, scientists found bright red lesions and darker purple areas of pulmonary inflammation in their lungs.

โ€œWe actually see that it replicates deep down in the lungs of the monkeys, which potentially could explain the disease in humans better,โ€ researcher Vincent Munster of the NIH/National Institutes of Allergy and Infectious Disease Rocky Mountain Laboratories in Montana told AFP in a phone interview.

โ€œThis kind of explains why this virus potentially could be fatal. If it replicates deep down in the lungs, eventually it could destroy the lungs' ability to take up oxygen and eventually cause severe disease,โ€ Munster added.

Kidney failure has been seen in people who have died of the disease, which was first detected last year.

The animal research is a โ€œfirst step toward getting to know what the virus does in humansโ€ and should help experts narrow down vaccine strategies and antiviral options for intervention, he told AFP.

The letter to the New England Journal of Medicine is the first to describe animal research on the virus. Previous attempts to study it in hamsters were of little use, Munster said.

But many questions remain about the virus, which seems to resemble Severe Acute Respiratory Syndrome (Sars) - which erupted in Southeast Asia a decade ago - and bird flu in the way it affects the lungs.

It is formally called hCoV-EMC/2012, which stands for human coronavirus-Erasmus Medical Centre, after the Dutch health institution that identified it.

The virus sample provided to researchers at the Rocky Mountain lab by Erasmus for the monkey research did not appear to cause the severe type of disease that has been seen in humans, Munster said.

That could indicate that there are more mild cases in circulation among humans, or it could reflect a difference in the way primates and humans react to the infection.

Current research has been limited to studying cases in people who have been hospitalised with severe illness.

The World Health Organisation reported in late March that a 73-year-old man from the United Arab Emirates had become the 11th fatality from novel coronavirus. The WHO has documented a total of 17 cases globally.

Also last month, scientists reported in Nature magazine that the virus appears to infect the body via a docking point in lung cells, and suggested bats may be a natural reservoir for it.

Researchers believe the virus can be transmitted from human to human, though such occurrences appear to be uncommon.

It remains unknown whether the disease is truly rare and acute, or if it may be more abundant but mild so as to escape detection most of the time. - Sapa-AFP
