H5N1 isn’t well adapted to humans, so person-to-person spread is not a worry – for now.

Infectious diseases can spill over from animals to humans as well as spill back. Each cross-species transmission gives pathogens a chance to evolve and spread even further.
The H5N1 virus has infected about 900 people since 2003, and more than half of them died. But so far there is no evidence of human-to-human transmission.
We actually already have some vaccines against bird flu. But scientists are working on vaccines that could be adapted more easily as the virus changes.
H5N1 is the latest evidence that climate change is altering how viruses spread and evolve. It is essential that global public health officials take these dynamics into account.
Raw milk has always carried the risk of serious illness, and this risk has only risen with bird flu spreading across dairy farms in the US.
Our approach to combating pandemics must shift to one that prioritizes prevention of human infections with zoonotic viruses, rather than focusing on rapid response once human infection is widespread.
Contact tracing didn’t identify any cases beyond this child. While the risk to the public is very low, the global situation with bird flu is precarious.
Migratory birds could bring the lethal bird flu variant that is assailing the rest of the world’s birds.
Before World War II, pathogens in milk accounted for 1 in 4 cases of foodborne diseases in the US. Pasteurization reduced this figure to less than 1%.
A veterinarian and epidemiologist who studies infectious diseases in dairy cows discusses the outbreak, how cows recover and what the government is doing to keep the milk supply safe.
H5N1 influenza has been reported in dairy cows, and detected in milk. Here’s a look at what’s known about how pasteurization affects the virus and the safety of consuming H5N1-contaminated milk.
Five livestock experts who study infectious diseases in the dairy industry explain the risks.
Bird flu in U.S. dairy cows has Canadian public health experts on high alert. With one human case identified in Texas, what is the likelihood of H5N1 influenza moving from birds to mammals to people?
Avian influenza has killed a polar bear and may have infected other bears.
A deadly strain of bird flu is circulating in animals. So far the virus has been detected in seabirds on islands near Antarctica. What does this mean for wildlife, tourism and research?
Vaccination against bird flu offers farmers hope, rather than being caught between the anguish of finding a sick bird and the desolation of having to slaughter their entire flock.
The first sign of a new bird flu might be a dead seabird or marine mammal. Better surveillance of migratory birds and wildlife – and better public awareness – is crucial.
After previous public health emergencies likes SARS and H1N1, there was renewed investment in pandemic preparedness, but it was not sustained. We cannot make the same mistake after COVID-19.
From cancer immunotherapy and antibiotics to GMO crops and pandemic surveillance, gain of function is a cornerstone of basic research.
