This disease is borne by rodents and is effecting several West African countries. In the past this disease was considered rare but there have been 353 confirmed cases in 18 states. There are 700 cases suspected and 110 people have died. The disease is difficult to diagnose and often goes unreported.

The virus was isolated when a third nurse was infected and rushed to a New York City hospital. A pathogen borne by rodents called arenavirus has been isolated as the cause. The disease is contracted when the droppings and urine of rodents searching for food come in contact with people. This can be caused by touching a contaminated surface, ingesting contaminated food or through the bodily fluids of an infected individual.
