For the first time in a long time, the Northeast is hearing about Legionnaire’s again, after a resurgence in the Bronx, N.Y. has led to the deaths of two people. Legionnaire’s is a form of pneumonia, which usually spreads through the condensation in air-conditioning ducts (it is not airborne, but carried by contaminated water). The disease got its name from an American Legion convention in Philadelphia in 1976 in which several people were infected. While Legionnaire’s cannot be passed from person to person, and is much more likely to breed in complex water systems (such as those in hotels and schools) than private homes, it never hurts to be careful, especially if you live in an affected area. Stay on the watch for flu-like symptoms, confusion, and a slowed heartbeat in combination with fever. Treatment with appropriate antibiotics can deliver a survival rate of up to 95% if medicine is started quickly. Do you think we get too worked up about communicable diseases, or not concerned enough? Do you panic when you hear about outbreaks such as this one? Share your reactions in the comments.
