The Bronx has seen an uptick in Legionnaires’ disease during the past month, and now city health officials think they may have pinpointed one of the sources. Co-Op City, a sprawling residential complex in the borough, has a cooling tower that has tested positive for the bacteria that causes the illness, says the Department of Health. Eight of the 12 people who’ve been diagnosed with Legionnaires’ — a severe and sometimes fatal form of pneumonia — live in the complex. Decontamination efforts are now under way in the tower, which supplies water for cooling and heating and not, thankfully, for drinking.
