An outbreak of Legionnaires’ disease in New York City has killed two people and sickened 58 since late July.

Fifty-eight people in New York City have been diagnosed with Legionnaires’ disease, a serious bacterial lung infection, and two people have died, according to the city health department.

There is no vaccine for Legionnaires’ disease. If diagnosed with the disease, you may need to go to the hospital. Medical staff may be able to give patients antibiotics or administer oxygen through a face mask or a breathing machine.
