The yardstick for human mortality from H5N1 is the case-fatality rate (CFR); the ratio of the number of confirmed human deaths resulting from infection of H5N1 to the number of those confirmed cases of infection with the virus.
From 1962 to 2022 there have been 157 recorded cases of the infection in United States, only 4 of those 157 individuals survived the disease. A combination of drugs have shown effectiveness in survivors. The rate drops significantly to >50% with treatment. The rate dropped significantly to 10% with effective treatments. Eradicated.
A person in Vietnam died of H5N1 infection around the same time, clade unknown. [40] In April 2024 the FAO reported that recent reassortment in the Greater Mekong Subregion has produced viruses that carry internal genes from the 2.3.4.4b lineage but the H5 gene from the older 2.3.2.1c lineage. These viruses have been implicated in human cases. [41]

US influenza statistics by flu season.

Frequency. 3–5 million severe cases per year [1][2] Deaths. >290,000–650,000 deaths per year [3][4] Influenza, commonly known as the flu, is an infectious disease caused by influenza viruses.

Transmission and infection of H5N1 from infected avian sources to humans has been a concern since the first documented case of human infection in 1997, [1] due to the global spread of H5N1 that constitutes a pandemic threat. Infected birds pass on H5N1 through their saliva, nasal secretions, and feces. Other birds may pick up the virus through ...
