Legionnaires' at Lehman HS disinfected

Trace amounts of Legionella bacteria were found in a cooling tower at Lehman High School in the Bronx. Crews worked through the night to disinfect the self-contained tower. Classes resumed as usual Wednesday morning. It is the latest case of the potentially deadly bacteria in the Bronx that killed 12 people over the summer.

"The water in the cooling tower is self-contained and is separate from the water used by the school," said NYC Health Commissioner Dr. MaryT. Bassett.

Ten people were hospitalized in recent weeks following a new outbreak in the Morris Park section of the borough. Nine people remain hospitalized. All had underlying medical conditions, according to Health Dept. officials.

Legionnaires' disease is treatable with antibiotics.

Symptoms include fever, chills, cough, muscle aches and difficulty breathing.
