A New Jersey man was diagnosed with Lassa fever this month, after his return from Liberia. The man died on Monday.
The fever is a viral disease common in West Africa. It exhibits similar symptoms as found in Ebola such as diarrhea, vomiting and bleeding. However, it is less infectious and far less likely to be fatal. Compared to about 70% of Ebola patients, about 1% of Lassa patients die.
