A mystery disease in Congo has led to over 50 deaths. Here's what to know about its potential to spread.

A mystery illness has caused over 50 deaths amid multiple outbreaks in the Democratic Republic of Congo, doctors say.

At least 431 cases have been reported across at least two villages in a northwest region of the central African nation, according to the most recent bulletin from the World Health Organization's Africa office on Feb. 16. 

Preliminary investigations traced the first outbreak to three children who became sick and died after eating a bat carcass, the bulletin says.
