The outbreak in New York City began in July, which affected dozens of people with severe Legionnaires' disease. The health department confirmed that 17 others are hospitalized as of Friday.

Dr. Toni Eyssallenne, Deputy Chief Medical Officer, in a statement previously suggested that anyone in New York who has flu-like symptoms must immediately visit a healthcare professional. He said, "Legionnaire's disease can be effectively treated if diagnosed early. But New Yorkers at higher risk, like adults aged 50 and older, those who smoke or have chronic lung conditions, should be especially mindful of their symptoms and seek care as soon as symptoms begin."

What Is Legionnaires' Disease?

Legionnaires' disease is a type of pneumonia, but a more severe form, caused by a bacterium called Legionella. According to the Centers for Disease Control and Prevention (CDC), anyone can contract this waterborne pneumonia illness when they breathe in the mist that contains the Legionella bacterium.

The World Health Organization (WHO) explains, "The most common form of transmission of Legionella is inhalation of contaminated aerosols from contaminated water. Sources of aerosols that have been linked with transmission of Legionella include air conditioning cooling towers, hot and cold water systems, humidifiers and whirlpool spas.

"Infection can also occur by aspiration of contaminated water or ice, particularly in susceptible hospital patients, and by exposure of babies during water births."

Signs And Symptoms Of Legionnaire's Disease

The signs and symptoms of Legionnaire's disease are similar to other types of pneumonia, which include cough, fever, headaches, muscle aches, shortness of breath, and individuals in severe cases may experience confusion, diarrhoea, or nausea.
