Sébastien Calvignac-Spencer studied the origins of Ebola virus that caused an outbreak in West Africa in 2014 .

He obtained the oldest known measles genome from a lung preserved in 1912 .

From this genome, he learned that our seasonal H1N1 influenza virus is likely a direct descendant of that pandemic-causing pathogen.

Scientists have found a complete genome of Spanish influenza in a German museum's pathology collection.

They used formalin-fixed lung samples to study the 1918 Spanish flu pandemic virus.

The researchers say they use complete personal protective gear to protect the specimen.

Their findings could help us better prepare for future outbreaks, they say.

Measles cannot persist unless a critical population size of about a quarter to a half-million people has been reached.

The more we let measles circulate in human populations, the more chances it has. Eradication is the only safe way to go. Now our study shows we have a tool that is almost perfect..
