WHO Alarmed by Surge in Human Bird Flu Cases

The World Health Organization (WHO) has raised alarms regarding the H5N1 bird flu outbreak, which began in 2020 and has since led to extensive loss of life among birds and mammals. The virus has also affected humans, and while there has been no evidence of human-to-human transmission, the mortality rate for those infected through animal contact is notably high. The WHO reported a 52 percent case fatality rate, with 463 deaths out of 889 human cases documented across 23 countries from the start of 2023 to April 1.

The UN health agency's chief scientist, Jeremy Farrar, described the situation as a global zoonotic animal pandemic, with the virus demonstrating the ability to infect new hosts, including cows and goats. The WHO's concern extends to the potential evolution of the virus and its implications for public health. Farrar has emphasized the necessity for increased surveillance, as well as equitable access to medical interventions such as vaccines, therapeutics, and diagnostics to address this growing health threat.
