The WHO has voiced 'enormous concern' about the spread of the H5N1 avian flu strain to new species, including a potential risk to humans.

Millions of poultry have died from an outbreak in 2020, and the virus has affected several mammal species, including domestic cattle in the US.

A recent outbreak in Texas cattle has escalated concerns due to previous assumptions that cattle were not susceptible to H5N1.

The virus's presence in dairy cattle across eight states has led to demands for more government transparency and information sharing.

There are worries about the safety of milk disposal and the virus spreading due to the government's perceived lack of data transparency.

The WHO cautions that the H5N1 virus could mutate to infect humans more easily and potentially transmit between humans.

Bird flu was found to be the cause of illness in dairy cattle in Texas, with the virus now present in multiple states and confirmed to transmit cow-to-cow and to at least one human.

Increased monitoring, development of vaccines, and equitable access to health resources are urged by the WHO to mitigate the threat of H5N1.
