The recent wave of avian influenza or bird flu that is spreading in Asia and Europe could have a greater risk of spreading to humans.
According to Reuters on Wednesday, Monique Eloit, the Director General of the World Organisation for Animal Health, said that the current situation is more risky as more variants have emerged.
She said that there is a risk of mutation or mixing with a human flu virus that can be transmitted between humans.
Bird flu has been detected in fifteen countries between October and the end of December according to OIE data.
Most cases were the H5N1 strain, one of the few bird flu strains that is transmissible to humans.
The outbreaks have led to the culling of millions of birds.
