The New York City Department of Health said in an update Aug. 4 that 58 people in Central Harlem have been diagnosed with Legionnaires' disease since July 25.

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.
