Avian flu, also known as bird flu, has raised significant concerns for the World Health Organization (WHO) as the H5N1 strain continues to spread to new species, including humans. Jeremy Farrar, head of the UN health agency, expressed “huge concern” over the potential for the virus to adapt to human-to-human transmission, highlighting the high mortality rate associated with the virus.
The WHO reported a total of 889 human cases of avian influenza in 23 countries, with a case fatality rate of 52%. Recent cases in Europe and the United States have sparked fears of transmission to humans, although current cases remain rare. Efforts are underway to develop vaccines and therapies for H5N1, with a focus on strengthening monitoring and ensuring equitable access to medical resources.
Farrar emphasized the importance of understanding the potential for human infections and the need for immediate response measures if human-to-human transmission were to occur. As the virus continues to seek out new hosts, global health authorities are urged to stay vigilant and prepared for any potential outbreaks.
