New York Cityhealth officials are urging anyone who has visited the east side of Central Park or Manhattan’s Upper East Side since late June to watch for symptoms.

Officials are investigating contaminated cooling towers as the likely source.They have emphasized that the illness is not spread person-to-person and is not linked to the city’s drinking water.

“Legionnaires’ disease is deadly but can be effectively treated if diagnosed early,” said NYC Health Commissioner Dr.Alister Martin in a press release.“New Yorkers at higher risk, including anyone who is 50 and older, those who smoke or people with chronic lung conditions should be especially mindful of their symptoms andseek careas soon as symptoms begin.”

What is Legionnaires’?

Legionnaires’ disease is a type of pneumonia caused byLegionella bacteria.

The bacteria is usually found in lakes, streams and other freshwater environments, but can grow in any area where water sits for a long time, according to the CDC.

That can include shower heads, sink faucets, hot tubs, water features/fountains, plumbing systems and other water systems.

When people swallow or breathe in droplets of water that contain Legionella, they can potentially become ill.

Although human transmission is possible in rare cases, the disease is not typically transmitted among people, per the Centers for Disease Control and Prevention.

Symptoms of infection

Infections can lead to severe pneumonia in older people and those with compromised immune systems, according to Dr.Andrew Handel, a pediatric infectious diseases expert at Stony Brook Children’s Hospital onLong Island, New York.

Symptoms of Legionnaires’ disease usually show up between two and 14 days after exposure.

“Legionella infections cause symptoms that are similar to other forms ofpneumonia— fever, coughing, difficulty breathing, shortness of breath and chest pain,�

Some patients may also experience nausea, diarrhea and confusion, the CDC noted.

Diagnosis, treatment and prevention

A medical professional can diagnose the infection with laboratory tests and chest X-rays.

The condition is typicallytreated with antibiotics.In cases of severe infection, hospitalization may be required for breathing support and IV hydration.

Around 10% of people who contract Legionnaires’ disease will die from those complications — and the mortality risk rises to 25% for those who get Legionnaires’ while staying in ahealthcare facility, according to the CDC.

“Treatment needs to be early and aggressive,” Dr.“Legionella infection is an intracellular infection that requires antibiotic treatment.”

Antibiotics that are appropriate for Legionella infection include Levofloxacin and Azithromycin.

“Therapy can be prescribed orally in healthy individuals… but intravenous antibiotics often prove to be the initial option for treatment secondary to the pathogenicity of the disease,” Goodyear said.

Currently, there are no vaccines for Legionnaires’ disease.

The best strategy to prevent infection is to reduce the growth and spread of the Legionella bacteria.The CDC recommends that building owners and managers use a water management program to reduce the risk.

“New Yorkers at higher risk, including anyone who is 50 and older, those who smoke or people with chronic lung conditions should be especially mindful of their symptoms and seek care as soon as symptoms begin,” city officials stated.(iStock)

To prevent serious illness from Legionnaires’, Goodyear recommends that all smokers kick the habit, and also emphasizes the need to “aggressively support” chronic pulmonary disease.

“Increasing immune support (vitamin D3, vitamin C, Zinc) is required to counter the immune dysfunction associated withadvancing age.”

Obesity is another foundational risk factor for all chronic inflammatory diseases, the doctor added.
