A fifth person has died in connection with a Legionnaires' disease outbreak on Manhattan's Upper East Side, according to health officials. 

Legionnaires' disease is a severe type of pneumonia caused by inhaling water droplets contaminated with Legionella bacteria.

Health officials announced in announcing the deaths Tuesday also said culture tests came back positive for the Legionella bacteria in 34 cooling towers at 33 buildings in New York’s Upper East Side. Nine cooling towers came back negative, and the remaining results for 140 cooling towers are anticipated to come in over the next week.

Those towers have since been drained, cleaned, and disinfected. Officials stated there have been no cases reported in six days, no new symptoms reported in more than 10 days, and they still believe the threat of exposure has been eliminated.

Overall, the city has reported 82 total cases since the outbreak started in early July; 56 people have been discharged from the hospital while eight remain hospitalized. The cluster of cases has been reported in ZIP codes: 10128, 10028, and 10075.

This outbreak comes as health officials monitor another disease outbreak spreading across the country. More than 6,000 people have been affected by the Cyclospora outbreak, a parasite that can cause severe gastrointestinal illness, though no deaths have been reported.

New York City reports hundreds of Legionnaires' disease cases each year. Last year, a separate outbreak in Harlem killed seven people and hospitalized dozens more. The cases, which were also linked to cooling towers, prompted the city to require more frequent inspections of equipment.

The disease is not contagious and can be easily managed with antibiotics. Most people who are exposed to the bacteria do not become dangerously ill. However, older adults, smokers, and those with pre-existing conditions are at a higher risk of severe illness.
