It's a Small World: A man in New Jersey has died of lassa fever, a virus that's common in West Africa, where he had recently travelled. He was asymptomatic on his flight home to New Jersey, however, so his fellow passengers should be safe:

We are comfortable that this case will remain an isolated case,'' Karabulut said.

Authorities said they were still trying to identify the flight the man was on, which landed in Newark, and that the CDC would attempt to contact those who were on the plane.

The man's family said he did not have symptoms of the disease, such as diarrhea, vomiting or coughing while on the flight, so there is little chance any other passengers were exposed, Bresnitz said.

Let's hope so.
