Bird (Flu) is the word.
The Ministry of Foreign Affairs of Russia has put out a statement alleging they found evidence of bioweapon creation in labs in Ukraine. They claim that it is a weaponized zoonotic version of bird flu.. This is not entirely unexpected and seemed inevitable after Russia’s outbreak of bird flu and the subsequent killing of chickens at poultry farms. The death rate for bird flu is around 40%
