Welcome to birdflustocks.com!
With fresh memories of Covid-19, most people refuse to even think about another pandemic. However, there were influenza type A pandemics of H1N1 in 1918, H2N2 in 1957, H3N2 in 1968, and H1N1 in 2009. With around one billion infections and several hundred thousand deaths, the H1N1 swine flu pandemic of 2009 was comparable to "only" an additional "flu season".
H5N1 infections are much more deadly. Every second documented patient died. Widespread human infections combined with double-digit case fatality rates would be catastrophic.
H5N1 continues to spread globally and during all seasons, both is unprecedented. As large numbers of mammals get infected by sick and dead birds, the probability of adaptation to mammals and sustained human-to-human transmission increases.
This website aims to provide all the facts needed for your own risk assessment, based on probability and impact. While the bird flu pandemic may never happen, it could also have a devastating impact, financially and otherwise.
Highly pathogenic avian influenza H5N1 was first discovered in Hong Kong in 1996. The new variant H5N1 clade 2.3.4.4b has spread from Europe around the world since its discovery in 2020. The map shows confirmed H5N1 infections of any clade in mammals and birds in late 2022 and 2023.

ideally a universal flu vaccine would create immunity
to portions of the flu virus that are common to all flu
strains, that when you do develop immunity to
your universal flu vaccine, the threat of seasonal flu
goes away, and the threat of bird flu goes away, and
the threat of pandemic flu goes away. That would be a

"You can find this trend around the world, almost anywhere you look. This virus has an extremely broad range of hosts that it is able to infect."

"Another question is how big a dose of vaccine you would need. H5N1 isn't something human populations have really been exposed to before, and at least with tests involving traditional vaccines, it takes a lot of vaccine to get a decent immune response. mRNA vaccines are already pretty reactogenic; they are associated with a bunch of mild, but common side effects. So, we don't know how mRNA will fare if big doses are needed."

"We did learn that we can develop a new vaccine very quickly if we all work together … and there are a lot of scientific advances on the horizon that I think would make us more prepared. But this is a really a population health challenge. It needs society to work together. If you have everybody hoarding toilet paper or masks or just looking out for themselves, that doesn't actually help them, because the virus continues to circulate."

"When extraordinary things happen, a common psychological response is to deny it. ‘It can’t be happening.’"

"Once the virus gains the ability to attach to the human receptor and then go human to human, that’s when you’re going to have the pandemic. And as I said, I think it’s just a matter of time."

"Whatever time we have, we’re squandering that by not acting more aggressively. It seems like we’re staring at the Titanic and the iceberg, and we’re just waiting to see if the ship turns at the last minute. That’s not a great strategy."

"If we don’t address the incentives and disincentives for dealing with the drivers of spillovers, which include politics, which include financial incentives, which include trade, which include food security, then I think we’re going to continue to struggle to deal with these types of zoonotic viruses."

"We should be very concerned at this point. Nobody should be hitting the panic button yet, but we should really be devoting a lot of resources into figuring out what’s going on."

"We need to get this thing out of the dairy cow populations, because if it continues to circulate in these populations, it’s just a matter of time before we’re dealing with the big outbreak. We have more than enough evidence now to know that we really need to take decisive action."
