The Lassa fever death of a man in New Jersey exposed weaknesses in the public health surveillance meant to catch Ebola cases.
The man was undergoing routine monitoring for Ebola after returning from Liberia 2 weeks ago, according to the CDC. But when he developed a fever, instead of checking in with county health officials he went to a hospital—where he says no when asked whether he had traveled to West Africa. They initially sent him home with antibiotics. He returned 3 days later, was found to have Lassa fever, and died several days later.
