The worst wave of bird flu to date has been raging worldwide for three years. The virus has long been killing not only birds, but also seals, bears and foxes. Can it also be dangerous to humans?
The list of dead animals is long: cranes in Israel, pelicans in Peru, bears in Canada, minks in Spanish fur farms, domestic cats in Poland. Thousands of dead sea lions washed up on the beaches of Chile, and the USA experienced a mass death of seals. A total of more than 100 million wild and domestic birds died worldwide. A virus is to blame.
