Doctors are on high alert over a mystery flu-like illness - with similarities to Covid-19 - that has people critically ill in Argentina.

International public health surveillance system, ProMed, issued an alert on April 17 after 60 cases of the unknown sickness were reported in Buenos Aires. This is the same database that first alerted authorities to Covid-19 back in late 2019.

The alert, submitted anonymously "via an individual known to ProMed", stated: "In the past 30 days, there appears to have been an increase in severe atypical pneumonia requiring critical care in Buenos Aires. The affected individuals are mostly young people without major risk factors."


While no official statements have been made by Argentinian officials, it's reported that patients have needed mechanical ventilation to help them breathe. Over a third of those affected showed symptoms of psittacosis, a disease caused by a type of chlamydia found in birds. However, many had no apparent history of contact with birds, the alert noted.

Psittacosis, also known as parrot fever, is causing concern with its flu-like symptoms that can escalate to pneumonia. It's a particular worry for the elderly or those with weakened immune systems, reports the Daily Star. The alert warned: "Although psittacosis appears to be the etiology of some of the cases, there may be more than one agent involved. ProMED would appreciate more information about these cases."

The Daily Mail reports that experts are urging health officials not to take the situation lightly, despite reassurances that it's "unlikely this will pose a threat more widely".

DJ, One would hope testing for H5N1 would detect H5N1 if there is H5N1....but testing may be far from perfect...

“In the current panzootic, the first case of H5N1 infection in mink in Spain probably occurred through contact with infected birds (perhaps seagulls). Ingestion of infected bird carcasses was likely the route of infection for red foxes in the Netherlands, Finland, and Japan during 2020-2022, American sea lions in Peru in 2023, various mesocarnivores in Canada during 2021-2022, and otters ( Lutra lutra ) and a lynx ( Lynx lynx ) in Finland in 2021-2022.

But they also warned of a risk . “Studies in infected tigers, farmed minks and social species such as fur seals are worrying, raising the alarm that mammal-to-mammal transmission may have occurred .” They acknowledged that “more research is needed to confirm this possibility.”

In South America, avian flu arrived in 2022 and caused massive mortalities in sea lions and elephant seals in Peru, Chile and Argentina. “Now there is a period of relative calm. But we must maintain vigilance,” Dr. Plaza told Infobae .

In Antarctica, as an international expedition warned days ago, avian flu is harming wildlife. Aboard a sailboat, researchers scoured the Weddell Sea and the Antarctic Peninsula for a month, and found carcasses of migratory seabirds similar to seagulls, called Antarctic skuas, with flu in four of the 10 areas analyzed.

They found 50 dead skuas. On Heroína Island, where there is a large colony of Adelie penguins, “a massive mortality of these animals was observed with more than 500 corpses in the investigated place, which suggests that an abnormal mortality event may have occurred in the that several thousand penguins would have perished,” they reported.

DJ...poultry litter but also insects could play a role in H5N1 spread in US cows;

At a recent meeting, scientists from the US Department of Agriculture stated that the virus does not occur as a respiratory disease in livestock. That means the animals don't seem to excrete large amounts of virus through their nose or mouth.

“I want to emphasize how unusual this is,” Thijs Kuiken , a professor of comparative pathology and avian flu researcher at Erasmus Medical Center in the Netherlands , told NPR radio . “In other mammal species with influenza viruses, it is primarily a respiratory illness, which does not appear to be the case in these cattle.”

Meanwhile, days ago, a group of scientists presented a study that revealed the presence of the H5N1 bird flu virus in at least a small fraction of the birds in New York . People often associate zoonotic diseases with rural environments, farms or natural spaces, said Florian Krammer, an influenza expert at the Icahn School of Medicine at Mount Sinai in New York who led the study. But New York City has many green spaces and bodies of water that are used by migratory and local birds.

In dialogue with Infobae , Dr. Sergio Lambertucci , researcher at the Biodiversity and Environment Research Institute (INIBIOMA) of Conicet and the National University of Comahue of Argentina , explained: “The avian flu infection is affecting more mammals as that time passes. The presence of the virus in cattle in the United States is worrying because they are animals that are more in contact with people.”

Currently, the avian flu situation is considered to be a “ panzootic ” because it is a serious infectious disease that spreads across large areas of the world and affects one or several species of animals in many countries.

“Panzootia has not yet conquered the entire planet, but it is going in that direction. “It did reach Antarctica, affecting several species already,” he noted.

DJ, H5N1 may already be "extreme" in both duration and spread...

Sunday night's excitement about an upload from   of sequence data on the #H5N1 #birdflu outbreaks in cows turned to frustration Monday as scientists realized key info had been left out of the files. Without it, it's very hard to assess what's going on. https://statnews.com/2024/04/21/usda-releases-h5n1-bird-flu-genetic-data-eagerly-awaited-by-scientists/

DJ...

Not including the #H5N1 goat infections from early March and not submitting the data to GSAID for peer review explains all you need to know about what the USDA doesn’t want you to know.

DJ...more and more the H5N1 story may become a "very bad news story" nobody is "jumping" to tell...Even if it is not yet spreading in humans it is high risk for lots of mammals, we need urgently to rethink food production (poultry/meat/eggs/diary...It starts hurting the economy..."Saving the economy at the cost of public health" is also ongoing with (denial of) CoViD...

Certainly if you work with animals protection (mask/eye-protection) is wise !

Bloomberg: The Bird Flu Outbreak Is Alarming. And the Government Is Stumbling. The H5N1 crisis at dairy farms shows that public health agencies have failed to absorb the lessons of Covid.

DJ...also some forms of CoViD (in Finland ?) missed some of the rapid-testing segments and could be missed...Both CoViD and H5N1 -by now- is very widespread. Testing alone can not stop it...vaccines have their limits...so Non Pharma Interventions (NPI=masks etc.) may need to increase.

Replying to 
But it looks to me like a strong possiblity that this has been circulating in cattle for  months under our noses, even before the first inkling there might be something new in February. This reveals massive gaps in our pathogen surveillance and detection systems.

Abstract

A quantitative understanding of the spread of contaminated farm dust between locations is a prerequisite for obtaining much-needed insight into one of the possible mechanisms of disease spread between farms.

 Here, we develop a model to calculate the quantity of contaminated farm-dust particles deposited at various locations downwind of a source farm and apply the model to assess the possible contribution of the wind-borne route to the transmission of Highly Pathogenic Avian Influenza virus (HPAI) during the 2003 epidemic in the Netherlands. 

The model is obtained from a Gaussian Plume Model by incorporating the dust deposition process, pathogen decay, and a model for the infection process on exposed farms. 

Using poultry- and avian influenza-specific parameter values we calculate the distance-dependent probability of between-farm transmission by this route. A comparison between the transmission risk pattern predicted by the model and the pattern observed during the 2003 epidemic reveals that the wind-borne route alone is insufficient to explain the observations although it could contribute substantially to the spread over short distance ranges, for example, explaining 24% of the transmission over distances up to 25 km.

India has experienced continual outbreaks of H5N1 HPAI virus since February, 2006 especially in Eastern India. Survivability in poultry faeces is an important determinant in evaluating the persistence of the virus in the poultry sheds and their vicinity. In this paper, survivability of Indian H5N1 HPAI virus in dry and wet poultry faeces at 42, 37, 24 and 4 °C, respectively is reported. The effect of different temperatures was determined by linear regression model and defined in terms of linear equation. The virus survived up to 18 h at 42 °C, 24 h at 37 °C, 5 days at 24 °C and 8 weeks at 4 °C in dry and wet faeces, respectively. The coefficients of determination (R2) values for dry and wet faeces revealed that the difference in viral persistence in dry and wet faeces at all temperatures was not very marked. Results of the present study indicated that H5N1 HPAI virus may remain viable for extended periods of time in faeces at low temperatures and may act as a long term source of influenza virus in the environment.

DJ, So H5N1 may go airborne and can survive in different temperatures for weeks...









And how many farms. Also have pigs? Once it gets into the pig population, we’re in serious trouble

and

The USDA is not providing this information. We know there was at least one mixed farm. We know goats and possibly pigs were infected. They are not even acknowledging this in the data.

DJ, neither info on when or where sequences were detected...makes it very hard to get good epidemological models...

H5N1 in mosquitoes Blood-engorged mosquitoes were collected at poultry farms during an outbreak of HPAI in Central Thailand during October 2005. These mosquitoes tested positive for H5N1 virus by RT-PCR *Filed under "Things I wish I hadn't Googled" https://pubmed.ncbi.nlm.nih.gov/18279078/

FDA finds traces of H5N1 bird flu viruses in grocery store milk but says pasteurized dairy products are still safe


By Brenda Goodman, CNN

.......Dr. Eric Topol, founder of the Scripps Research Translational Institute, said the finding of viral particles in milk on grocery store shelves means the outbreak is probably more widespread than we’ve known.

“The dissemination to cows is far greater than we have been led to believe,” Topol said in an email Tuesday.

“The FDA assurance that the dairy supply is safe is nice, but it’s not based on extensive assessment yet, which they acknowledge, and won’t engender trust and confidence because it comes in the wake of USDA mishandling,” he added.


.....The USDA said it has encouraged farmers and ranchers to report cases of sick cattle to state animal health officials.

But neither cows nor the people who work or live around them are being widely screened for the infection, which would require informed consent. Testing of wastewater in areas with outbreaks is also being discussed.

.....
Instead, the CDC is monitoring emergency department data and flu testing data in areas where H5N1 viruses have been detected in dairy cattle for any unusual trends in flu-lik...e illness, flu or conjunctivitis. “So far, these data remain in expected ranges, and to date, surveillance systems do not show any unusual trends or activity,” according to information in a statement compiled by officials at the CDC.

CDC spokesperson Jason McDonald said that 23 people with exposures to H5N1 had been tested, including one person in Texas who previously tested positive. No other people have tested positive in the current outbreak, he said.
