Situation Update. November 18, 2024 – CDC continues to respond to the public health challenge posed by a multistate outbreak of avian influenza A(H5N1) virus, or "H5N1 bird flu," in dairy cows, poultry and other animals in the United States.CDC is working in collaboration with the U.S. Department of Agriculture (USDA), the Food and Drug Administration (FDA), Administration for Strategic ...
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus, which causes influenza (flu), predominantly in birds. It is enzootic (maintained in the population) in many bird populations, and also panzootic (affecting animals of many species over a wide area). [1]
H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows with several recent human cases in U.S. dairy and poultry workers. While the current public health risk is low, CDC is watching the situation carefully and working with states to monitor people with animal exposures.
CDC provides an update on its response activities related to the multistate outbreak of avian influenza A (H5N1) virus, or "H5N1 bird flu," in dairy cows and other animals in the United States.
H5N1 influenza virus infection can cause a range of diseases in humans, from mild to severe and in some cases, it can even be fatal. Symptoms reported have primarily been respiratory, but conjunctivitis and other non-respiratory symptoms have also been reported.
Highly pathogenic avian influenza variants such as H5N1 and H7N9 have been transmitted to humans. New variants of avian influenza viruses are emerging as a result of hosts carrying multiple viral...
Avian influenza A (H5N1), or bird flu, has killed millions of wild birds, and caused sporadic outbreaks among poultry and an ongoing multistate outbreak among cows in the United States. While there has been no known person-to-person transmission of the virus, there have been 46 reported human cases in the U.S. in 2024.
Avian influenza, commonly called “bird flu,” is a viral infection that usually spreads in birds but can sometimes spread to humans. Influenza A(H5N1) is the most common cause in humans. It can cause severe respiratory symptoms. People who work with poultry, waterfowl (like geese and ducks) and livestock are most at risk.
Here we explore the molecular and ecological factors driving H5N1’s sudden expansion in host range and assess the likelihood of different zoonotic pathways leading to an H5N1 pandemic.
The H5N1 bird flu virus that infected the teen, who is in critical but stable condition, is not the same strain that is transmitting in dairy cattle in the United States. It is more closely ...
