A/H5N1 virus can also infect mammals (including humans) that have been exposed to infected birds; in these cases, symptoms are frequently severe or fatal. [2] A/H5N1 virus is shed in the saliva, mucus, and feces of infected birds; other infected animals may shed bird flu viruses in respiratory secretions and other body fluids (such as milk). [3]
There have been studies of the levels of cytokines in humans infected by the H5N1 flu virus. Of particular concern is elevated levels of tumor necrosis factor-alpha (TNFα), a protein that is associated with tissue destruction at sites of infection and increased production of other cytokines. Flu virus-induced increases in the level of ...
Amid an ongoing outbreak of bird flu among poultry and dairy cows, the United States has recorded its first human death due the virus known as avian influenza A or H5N1. The Louisiana patient died ...
The true fatality rate may be lower because some cases with mild symptoms may not have been identified as H5N1. [3] H5N1 infections in humans are generally caused by bird to human transmission of the virus. Until May 2006, the WHO estimate of the number of human to human transmissions had been "two or three cases".
61 cases of human bird flu in the U.S. in 2024. Since the start of 2024, human H5N1 bird flu cases have been reported in the following states, according to the latest CDC data: California: 34 ...
What we think of as the seasonal flu in humans is caused by types A and B. Bird flu falls under the umbrella of influenza A viruses. The strain currently spreading in the U.S. is H5N1, an HPAI ...
Here are five things you should know about bird flu. What type of virus is it and how does it spread? H5N1 comes from a group of four flu, or influenza, viruses: A, B, C and D. The strain called ...
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]
