Health officials say a 5-year-old New York City boy who tested negative for Ebola has a respiratory infection.

The boy returned from Guinea with his family Saturday and felt sick Sunday, so his parents called 911. Emergency responders in protective gear took him and his mother to Manhattan’s Bellevue Hospital.

Health officials said Tuesday that further testing confirmed he does not have Ebola. He will remain hospitalized but has been removed from isolation. His mother is doing fine.

A doctor who also was in Guinea remains in serious but stable condition after testing positive for Ebola last week. He had been treating patients with the virus.

Four people have been diagnosed with Ebola in the U.S.
