Foreign media quoted the World Health Organization report on Wednesday (1st) that a woman in Jiangsu Province was confirmed to be infected with H5N1 bird flu, which is similar to the strain of the human infection in Cambodia a week ago.                        

 The report stated that the infected Jiangsu woman was 53 years old. After contact with poultry, she developed symptoms on January 31 this year, but her specific condition has not been announced. According to the report, the genetic sequencing of the virus showed that the newly discovered case of bird flu in China was caused by the H5N1 virus strain 2.3.4.4b, which has widely appeared in the world.

DJ; One would expect more human cases if it spreads more easy...

It does seem highly suspicious that we're seeing cases of H5N1 simultaneously in different countries, Cambodia, Chile, China.....

Josh your point about mosquitos is very scary.

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

British press reporting a second case in China, of a slightly different clade of bird flu, in a middle aged man 800 miles from the first case.

Maybe to put things in perspective [url]https://afludiary.blogspot.com/2023/03/who-confirms-h5n1-case-in-jiangsu-china.html[/url] or https://afludiary.blogspot.com/2023/03/who-confirms-h5n1-case-in-jiangsu-china.html

Unlike last week's Cambodian cluster, this virus is of the same clade as the H5N1 viruses that are currently spreading across Europe, North America, and South America. 

There are, however, dozens of genotypes within this clade, and it is likely some are more dangerous than others (see Preprint: Rapid Evolution of A(H5N1) Influenza Viruses After Intercontinental Spread to North America). 

Given the amount of bird flu circulating in the wild around the world, we should expect to see additional cases in the weeks and months to come.

For those who have been along for much of this ride over the past 20 years, you know we've been here before, and that today's handful of H5N1 cases pale in comparison to the thousands of human H5 & H7 infections we've seen in the past (see graphic below).

Officially, there have been 870 human H5N1 infections, 84 H5N6 infections, and nearly 1,600 H7N9 infections.  All of these are likely under counts, and these numbers don't include the scores of H9N2 and sporadic human infections with H7N4, H10N3, H3N8, H7N2, etc. that have been reported. 

The period between 2013 and mid-2017 saw the highest number of human infections with (H7 & H5) avian flu, averaging several hundred each year.  In a few cases, H-2-H transmission appears to have occurred. 

Luckily, these viruses were far better at jumping from poultry to people, than from human-to-human. The concern is that these viruses - as they occasionally spillover into humans and other mammals - could pick up host adaptations that will allow the virus to spread more efficiently among humans. 

So...yes H5N1 now is a problem...but still limited...

Time will tell-there should be extra testing if "politics" take healthcare serious...

China has reported a new human H5N1 avian flu case, marking the second case in recent months, an official with the World Health Organization (WHO) confirmed today. Daniel Epstein, with the WHO's news media team, said China informed the WHO about the case on Feb 24. The patient is a 53-year-old woman from Jiangsu province who has a history of contact with poultry. The woman's symptoms began on Jan 31, and she was hospitalized on Feb 4. Genetic sequencing suggests that she was infected with the 2.3.4.4b H5N1 clade, which is currently circulating widely in birds, Epstein said. "Since 2020, an increased number of avian influenza outbreaks have been reported in wild birds and poultry globally, and we can expect additional sporadic human cases."
