Marburg virus kills 10 in Rwanda. What to know about the Ebola-like outbreak and symptoms

Ten people have died in Rwanda from the highly contagious Marburg virus, and 29 cases have been confirmed, the country's health ministry reported Tuesday, just days after the country declared an outbreak of the deadly hemorrhagic fever that has no authorized vaccine or treatment.

"Marburg is a rare disease," health minister Sabin Nsanzimana said Sunday. "We are intensifying contact tracing and testing to help stop the spread."

He said the source of the disease has not been determined yet.
