    A recent outbreak of

    Legionnaires' disease in New York City has led to seven deaths and over sixty hospitalizations. The bacterial

    infection is generally found in water, but can also be present in soil is commonly spread

    through mist including that

    from air conditioning and showers.

    Luckily, the disease can not be

    transmitted from person to

    person. However, that poses an increased challenge of determining the cause of the outbreak.

    The latest outbreak in New

    York has led investigators to a cluster of five buildings, including a hotel and a hospital, that have all

    tested positive for the legionella bacteria. Appropriate measures are being taken to ensure the bacteria is fully depleted.

    The legionella bacteria typically thrives in temperatures between 25 and 45 C (77 to 113 F). With the

    recent heat wave, the temperatures have given the bacteria an ideal environment to continue to replicate. However, the higher temperatures are also leading the buildings in New York to generally use more air conditioning and water consumption, leading to potential human contact.

    Symptoms of Legionnaires' disease are similar to those of influenza, including respiratory symptoms such as chills, fever and cough. In the United States, between 8,000 and 18,000 patients are annually hospitalized from the disease.
