This is MUCH WORSE than I had imagined. An entire plane was exposed. He was symptomatic. If it is spreading person to person we are in trouble.

Hi Dr. Tiffany!

We are requesting a clarification about your reports of a human avian flu case in Houston.
Which strain is this?
What is your source since you are located in another state?
Is this case confirmed test positive?
Which hospital is this case in?

Thank you!

It is H5N1, confirmed by genetic sequencing.


Nothing on the Houston department of health site link

Possibly they are waiting for confirmation testing from the CDC in Atlanta. That would be protocol....

DJ....I was optimistic on H5N1 spread most from birds to birds...limited from birds to mammals...We have to wait for more info...

I "googled around" ;

[url]https://www.democraticunderground.com/113514034[/url] or https://www.democraticunderground.com/113514034 ;

Has anyone heard anything about this? Supposedly a traveler on a flight from Hong Kong to Houston (arrived Tuesday night) has been confirmed to be infected with avian flu. I just saw a TikTok video posted this afternoon by an ER doc about it who believed it is the H5N1 strain. The doc did not know if it was capable of spreading from person to person. I have not seen any news reports of this case so I am posting this here. A Reddit thread about this case was deleted due to a lack of proper sourcing which corresponds with my inability to find anything on it.

With several recent reports of avian flu jumping to mammals, this case is worth monitoring if it indeed is true.

I don't think any of us want to go through this again so hopefully this case is not transmitted from human to human.

DJ...2 replies basic (also) trying to get more info....Tuesday-night meaning tuesday-to wednesday so february 7-8 ? Enough time for testing....

[url]https://www.reddit.com/r/collapse/comments/10y8gnn/doctor_reporting_a_apparent_case_of_bird_flu_in/[/url] or https://www.reddit.com/r/collapse/comments/10y8gnn/doctor_reporting_a_apparent_case_of_bird_flu_in/ ;

Rule 5: Content must be properly sourced.

Articles, charts, or data-driven content must include a source either within the image or in a submission statement.

DJ....[url]https://www.thailandmedical.news/news/health-news-we-are-living-in-dark-times-governments-and-health-agencies-around-the-world-are-not-telling-us-the-truths-of-what-are-really-brewing[/url] or https://www.thailandmedical.news/news/health-news-we-are-living-in-dark-times-governments-and-health-agencies-around-the-world-are-not-telling-us-the-truths-of-what-are-really-brewing claiming there would be lots of human H5N1 cases ...but kept out of the news...

However their link [url]https://www.gov.uk/government/news/bird-flu-avian-influenza-latest-situation-in-england#full-publication-update-history[/url] or https://www.gov.uk/government/news/bird-flu-avian-influenza-latest-situation-in-england#full-publication-update-history is on H5N1 in (UK) birds...not humans...

TMN lost a lot of credit for me....

If the CDC had more info [url]https://wwwnc.cdc.gov/travel/[/url] or https://wwwnc.cdc.gov/travel/ I do think they would provide it....

DJ-My view is there was NO case of H5N1 on the Hong Kong-Houston flight...possibly another disease ? Communications are complex...a newsrelease there is NO H5N1 spread in humans could create unrest they try to avoid....Yes-there are human cases with H5N1 but-so far-as good as all of them may have infected bird links...(as far as I know...)

On H5N1 potential risk for humans a.o. [url]https://afludiary.blogspot.com/2023/02/preprint-avian-influenza-virus-tropism.html[/url] or https://afludiary.blogspot.com/2023/02/preprint-avian-influenza-virus-tropism.html ;

#17,280

The $64 question with any emerging disease is whether it can successfully adapt to, replicate within, and spread between humans.  When that happens - and assuming humans have little or no existing immunity - it can spread as an epidemic or even a pandemic.

Influenza viruses - all of which appear to have originated from avian species - have managed to adapt to new hosts - including humans, horses, and swine - over thousands of years. 

Twenty years ago, dogs and cats and bats were thought immune to influenza viruses, but in the early 2000's we saw equine H3N8 jump from horses to dogs for the first time (see EID Journal Influenza A Virus (H3N8) in Dogs with Respiratory Disease, Florida), while on the other side of the world, we were seeing big cats (tigers) infected, and dying from avian H5N1 in Thailand. 

Since then, we've seen a number of flu strains infecting companion animals - and occasionally jumping to humans - including avian H7N2 at a New York City animal Shelter (see J Infect Dis: Serological Evidence Of H7N2 Infection Among Animal Shelter Workers, NYC 2016).

-

Most AIV subtype infections were caused mainly by exposure to infected poultry, suggesting that human-to-human transmission of AIV is still ineffective. However, given what we currently know about the rapid adaptation of AIV, efficient human-to-human transmission is possible, and it is just a matter of time before it happens.

DJ...My limited, non expert view; So far there are few reports of H5N1 spreading between humans [url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367332/[/url] or https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367332/ Thailand 2004 H2H story in [url]https://www.nejm.org/doi/full/10.1056/NEJMoa044021[/url] or https://www.nejm.org/doi/full/10.1056/NEJMoa044021 ;

CONCLUSIONS

Disease in the mother and aunt probably resulted from person-to-person transmission of this lethal avian influenzavirus during unprotected exposure to the critically ill index patient.

DJ Maybe H5N1 in humans result in limited/low viral load/spread during most of the infection ? 

However;

-H5N1 spread in birds is at a level unseen in history...

-Therefore there will be more spread from birds into mammals (via eating infected bird/bird droppings...)

-Both high spread of H5N1 in birds and mammals can result in new variants (mutations, co-infections with other flu types, recombination)

So YES H5N1 [url]https://en.wikipedia.org/wiki/Influenza_A_virus_subtype_H5N1[/url] or https://en.wikipedia.org/wiki/Influenza_A_virus_subtype_H5N1 is high risk....

If there was a case of H5N1 -infected passenger on a flight risk of spread to other passengers/crew -in general- is considered to be low. 

[url]https://afludiary.blogspot.com/2023/01/ukhsa-risk-assessment-on-avian-h5n1-4th.html[/url] or https://afludiary.blogspot.com/2023/01/ukhsa-risk-assessment-on-avian-h5n1-4th.html ;

Updated 31 January 2023

Background

From 2003 until 25 November 2022, 868 confirmed human cases and 457 deaths due to avian influenza A(H5N1) had been reported to the World Health Organization (WHO) from 21 countries.[footnote 1]

Highly pathogenic avian influenza (HPAI) A(H5N1) was first reported in the Far East, but is now enzootic in poultry across Asia and Africa. Although there have been very few human cases of A(H5N1) reported since 2015, outbreaks of HPAI A(H5N1) have occurred among poultry in several countries across Africa, America, Europe and Asia.[footnote 2]

The vast majority of human cases have reported contact with poultry and there is no reported evidence of sustained human-to-human transmission. No major changes have been detected in recently characterised viruses from human cases.

DJ,

You have a "pandemic triangle" ; Disease-transport-host...

In pandemics transport is the "weak spot". We should stop "virus-fly-for-free" massive global airtravel....We transport more then we want to transport....

Case definition for possible cases of A(H5N1)

  • Clinical criteria fever ≥ 38°C
or 
  • acute respiratory symptoms (cough, hoarseness, nasal discharge or congestion, shortness of breath, sore throat, wheezing or sneezing)
or
  • other severe or life-threatening illness suggestive of an infectious process

Additionally, patients must fulfil a condition in either category 1 or 2 of the exposure criteria below.

DJ,

Symptoms of H5N1 look a lot like CoViD....testing is a basic way to control disease...Masks may prevent a lot of infections....So IF you want global massive air travel testing for diseases, masks would be usefull....

For climate reasons we should -also- limit airtravel to "essential only" (goods/HCW-ers to disaster areas...)...

DJ-So even if ther was a case of H5N1 on a Hong Kong-Houston flight the view is risk would be "low"....

We cannot solve our problems with the same thinking we used when we created them.

Wow. Great find Roni and good work Josh. I hadn't heard anything about this. I certainly wouldn't want to have been a passenger on that flight even if H2H transmission is unlikely. As with all zoonotic illnesses, someone has to be patient zero.

Those who got it wrong, for whatever reason, may feel defensive and retrench into a position that doesn’t accord with the facts.

Here is an extract from an interesting report on H5N1 and known family clusters in humans and it discusses H2H transmission. 

The entire report can be found here

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2857285/

and this is the extract that interested me the most. It's a study of 2 out of 31 family clusters of H5N1:



Highly pathogenic avian influenza A (HPAI) subtype H5N1 is repeatedly crossing the species barrier to humans. Since December 2003, a total of 291 cases of HPAI (H5N1) have been reported in humans, resulting in 172 deaths (i.e., 59% case-fatality ratio) in 12 countries, mostly in Southeast Asia (1). Among these cases, 31 family clusters have been documented, ranging in size from 2 to 8 family members. How many of these clusters are due to a common avian source and how many are due to human-to-human transmission are important facts to determine. Should one of these HPAI (H5N1) strains gain the capacity for sustained human-to-human transmission, the resulting outbreak, if not contained, would spread worldwide through the global transportation network more rapidly than adequate supplies of vaccine matched to the new variant could be manufactured and distributed (2,3). We analyzed data from 2 of the largest of the familial clusters to ascertain if human-to-human transmission took place, and if so, how transmissible the strain was.


Methods

May 2006 Human Avian Influenza Family Cluster, Indonesia

During late April and early May 2006, a cluster of 8 cases of HPAI (H5N1) was detected and investigated by the Indonesian public health surveillance system in northern Sumatra (46). All case-patients were members of the same extended family. Seven of them resided within 3 adjacent houses in the village of Kubu Sembilang. The remaining patient resided with his immediate family in the village of Kabanjahe (≈10 km away).

The index patient was a 37-year-old woman, thought to have been exposed to dead poultry and chicken fecal material before onset of illness. She also reportedly maintained a market stall that sold live chickens. Although her illness was not confirmed to have been caused by the (H5N1) avian influenza virus, her death on May 5, 2006, is suspected to be the result of HPAI (H5N1) infection because of her reported symptoms, illness progression, and prior contact with diseased or dead poultry.

Twenty members of her extended family are suspected to have been in contact with her, many during a family gathering on April 29, 2006 (7). At that time, she was manifesting symptoms (i.e., she had a heavy cough, was severely ill, and was prostrate). That night, 9 of these members slept in the same small room as she did (indicated by a black triangle in Appendix Figure 1). Of these 9 family members, 2 of her sons (15 and 17 years of age) and her 25-year-old brother, who lived in Kabanjhe, became ill in the next 3 weeks. The sons died. The brother was the only person from this family cluster to recover.

Of the remaining 11 family members, 4 became ill and died. The 29-year-old sister of the index patient, who lived in an adjacent house, became ill after she provided direct personal care to her ill sister (7). The 18-month-old daughter of this sister also became ill after she was in the presence of the index patient with her mother. The 10-year-old nephew of the index patient, who lived in the other house adjacent to hers, became ill after he attended the family gathering and frequently visited his aunt’s house. The nephew’s father became ill after he personally cared for his son. The possibility that HPAI (H5N1) was transmitted from the nephew to his father is also supported by genetic sequencing data (4). Though symptoms did not develop in the mother of the nephew, she was directly exposed to her husband during his illness. All case-patients, except for the index patient, were confirmed as influenza (H5N1) positive by PCR. The nephew’s mother was confirmed as influenza (H5N1) negative. As an intervention, 54 surviving relatives and close contacts were identified and placed under voluntary quarantine (7). All of these persons, except for pregnant women and infants, received oseltamivir prophylactically.

December 2005 Human Avian Influenza Family Cluster, Eastern Turkey

From December 18, 2005, (8) to January 15, 2006 (9), a cluster of 8 confirmed (H5N1) influenza cases was detected in Dogubayazit District in eastern Turkey (Appendix Figure 2) (1013). These case-patients were among 21 members of 3 households located within 1.5 km of each other (14). All confirmed case-patients were hospitalized after onset of symptoms (9). Four of the confirmed case-patients died; the other 4 recovered (9). Ten of the remaining 14 household residents were hospitalized with avian influenza-like symptoms but were never confirmed to be (H5N1) infected (9). All but one of the hospitalized residents were children (6–15 years of age) (9).

Before onset of symptoms, 4 children from 1 household, 3 of whom had confirmed cases (including the index patient), were reported to have had close contact with the dead bodies of sick chickens (15). The 2 confirmed case-patients in the second household reportedly slaughtered a duck together on January 1, 2006, at the beginning of a die-off in the household’s flock (14). Two of the remaining confirmed case-patients lived in the third household and had no history of contact with sick or dying poultry. The remaining confirmed case occurred in a fourth residence located near the first household (10), but because we lacked information on the number of household members and the case-patient’s exposure history, we excluded it from these analyses. Most, if not all, of the 21 residents attended a dinner hosted by the family of the index patient on December 24, 2006, while he was symptomatic (8).

Those who got it wrong, for whatever reason, may feel defensive and retrench into a position that doesn’t accord with the facts.

DJ...lots of H5/H7 etc cases in humans will be missed...Even H2H -human to human- spread might be missed....

From Flutrackers [url]https://flutrackers.com/forum/forum/the-pandemic-discussion-forum/960736-avian-flu-discussion-global-widespread-bird-outbreaks-incl-africa-asia-europe-india-and-north-america-news-case-lists-links-2022?view=stream[/url] or https://flutrackers.com/forum/forum/the-pandemic-discussion-forum/960736-avian-flu-discussion-global-widespread-bird-outbreaks-incl-africa-asia-europe-india-and-north-america-news-case-lists-links-2022?view=stream (latest updates) H5N1, H5N6, H9N2, H10N3, H3N8 human recent Chinese (human) cases...

It would be welcome if human H5 etc cases did see more sequencing...also more testing of high risk groups (poultry workers)  to look for a/pre-symptomatic cases...

The Twitter account is unverified, so to be fair to the licensed doctor whose information you found that seems to match the Twitter account, you could call the doctor directly and make sure the two people are the same.

Here's what the verified Houston Public Health department is saying currently:
https://twitter.com/HoustonHealth/st...28524675080193

@HoustonHealth

The @HoustonHealth Department as of right now doesn’t have any reports of an avian flu case. Our staff checked with all local hospitals and none report an avian flu case.

I have not heard back from either the US CDC or the Texas State Department of Health as of this time. And now it is the weekend.

We have done this type of investigation many times in the last 17 years. FluTrackers contacts the various entities via phone and email to ascertain the truth.

We do not bash. We are respectful as we analyze the results of our search. We just want the information.

DJ...there may be several people -in several positions- having more info. From the airline to Houston airport-workers, Houston/Texas/US - or Hong Kong/China healthcare people...Maybe also a hospital in Texas ???? Point is somebody could learn (s)he tested positive for H5N1 during the flight...lots of H5N1 infected people had NO symptoms....(and may be of low risk for others...). 

Maybe even the "positive for flu" story itself was unclear..."translated" into positive for H5N1 when a person tested positive for "flu" (and not for CoViD) ????

A story can start by a crew-member making a remark to another crew-member and go "its own way"...Without any proper source the story stays on "rumour-level"....

@Tifftastic75

She has retracted her news because it did not verify with official sources.

Thank you to Dr. Tiffany for the effort. It is greatly appreciated.

Thank you to the state and local officials who responded to our inquiries - especially on the weekend.

We continue to monitor avian flu developments in Texas, the US, and all over the world.

If there are any more updates to this situation we will update this thread.

Dr. Najberg thought it best to take down her social media posts on this case for the time being. She plans to wait until the end of the day, Monday, to see if there is official confirmation. If not, she said she will retract the story. She thought the story was credible and still trusts her contact, but the contact is not involved in the case. She said that it is possible that she was misled, but also hopes there is no H5N1 bird flu case.

DJ; A medical doctor has been on social media today declaring an avian flu case in Houston via Hong Kong.

Could it be there was an infected animal on that flight ????? Or was the flu case not avian ????
