COVID-19: Are you ready for the next normal?


Two people developed Legionellosis in Ocean City, Maryland

At least two people have developed Legionnaire’s disease while recently vacationing in a hotel in Ocean City, Maryland, according to the Worcester County Health Department.  Health officials determined there were low levels of Legionella bacteria after testing water samples from the hotel’s potable water system.

Legionnaire’s disease (LD) is a form of pneumonia caused by exposure to the aquatic bacteria known as Legionella pneumophila.  You can be exposed to Legionella by inhalation of aerosolized Legionella contaminated water droplets or by aspiration or choking on Legionella contaminated drinking water.  LD develops 2-14 days after exposure and symptoms include fever, cough, shortness of breath, flu-like symptoms such as chills and body aches, and confusion or other mental changes.  LD is diagnosed by a medical provider and antibiotics are required for treatment. Fortunately, not everyone who is exposed to Legionella will develop the illness and the disease is not spread from person to person.

Typically, if building related LD is confirmed, a full scale investigation should commence. The many steps include determining if your building has water systems contaminated with Legionella by conducting a building investigation, risk assessment and causation analysis.  The expert response team of medical and environmental specialists can identify areas susceptible to the growth of Legionella, manage the incident, perform medical evaluations or surveillance activities (if necessary), conduct town hall meetings, and help create a remediation and preventive maintenance plan if Legionella source is found.
