A recent outbreak of Legionnaires’ disease in Central Harlem, a neighborhood in New York City, has led to a number of illnesses and some deaths. So far, five people have died, and over 100 people have been confirmed to be sick. The city's health department has been tracking the outbreak since it began in late July. They've found that the number of new cases is going down, which suggests their efforts to clean up the source have been working. Still, they are continuing to investigate and monitor the situation. The outbreak was traced back to cooling towers in the area. Cooling towers are a part of a building's air conditioning system that uses water to help cool it down. The city health department tested all the cooling towers in the affected areas and found that 12 of them had the bacteria. They have all since been cleaned and treated. Health officials have said that the issue is with the cooling towers, not with the regular hot or cold water in the buildings, and that it's safe for people to continue using their air conditioners. Can It Spread From Person To Person Contact? Legionnaires' disease is not contagious, so you can't get it from another person. The disease is mainly spread when someone breathes in tiny water droplets (called aerosols) that are contaminated with the Legionella bacteria. While it's not common, you can also be exposed by breathing in contaminated soil or, in rare cases, by accidentally breathing in water while drinking it. Whether a person gets sick after exposure depends on a few things: their overall health, how much of the bacteria is in the air they breathe, and how contaminated the source of the bacteria is. What Caused The Sudden Surge In Numbers? As of Monday, 14 people were hospitalized according to the health department. However, within the span of 5 days the number of infections has jumped to 108 people. Harlem City Councilmember Yusef Salaam, in a press conference last week urges people to visit the doctor if they exhibit any flu-like symptom to visit the doctor. "This is the time for you to actually go and seek medical attention. That's how serious this is." How Long Does It Take For Legionnaires Symptoms To Appear? Legionnaires’ disease is a serious type of lung infection, or pneumonia. People can get sick by breathing in tiny water droplets that contain the bacteria. The symptoms can take up to two weeks to appear and often feel like a bad case of the flu, including a cough, fever, chills, headaches, and muscle aches. The disease got its name from an outbreak in 1976 among a group of veterans at a convention. While the disease is not very common, it is becoming more of a concern nationwide, with research suggesting that hotter, more humid weather might be a reason for the increase in cases.
