Avian influenza viruses have evolved to infect birds, but the current H5N1 outbreak is also infecting a wide range of mammals. This suggests that it could mutate into forms that threaten humans.
It’s likely a combination of the incidence of viral outbreaks increasing, and the fact we’re getting better at detecting them.
Marburg virus spreads through close contact with infected body fluids.
The Marburg virus, a close cousin of Ebola, currently has no approved treatments or vaccines to protect against it.
Wild birds like pelicans and ducks are getting infected with – and dying from – a new strain of avian influenza and have spread it to farm animals around the world.

Fossil evidence of how the earliest life on Earth came to be is hard to come by. But scientists have come up with a few theories based on the microbes, viruses and prions existing today.
Communal bathing can get pretty disgusting.
Relaxing in filth – you may never want to use a hot tub again after reading this.

Ruth Itzhaki has spent more than 30 years researching whether certain common viruses play a role in the development of Alzheimer’s. But for years her research was greeted with hostility.
Genetic research is big business and has yielded life-saving treatments. But experts are warning of caution about ‘gain of function’ research that has the pandemic potential.
