Lassa fever is spread primarily by rats. Rats that carry the Lassa fever virus live in homes and areas where food is stored. People usually become ill with Lassa fever after direct contact with rat droppings or urine and through touching objects or eating food contaminated with rat droppings or urine.

Lassa fever may also spread when a person comes into contact with an infected person’s blood, tissue, or body fluids, especially when that person is seriously ill.
