It is a disease caused by bacteria called “Legionella”. This disease got its name in 1976. It occurred when a group of people at a convention of the American Legion in Philadelphia contracted it.

How Many People Are Infected Annually?

In the United States alone 8,000-18,000 people are infected with Legionnaires’ disease each year. It is unknown whether this is an accurate account because a lot of cases go unaccounted for.

When Are Cases of This Disease Common?

The majority of Legionnaires’ cases occur during summer and the beginning of autumn. However, this disease can be contracted any time of year.

What Are the Symptoms of Legionnaires’ Disease?

The symptoms of Legionnaires’ disease are often similar to pneumonia, which is why it often goes undiagnosed. Some of the signs and symptoms are:

  • High fever
  • Chills
  • Coughing
  • Muscle aches/weakness
  • Headache

In order to perform Legionella testing services, doctors sample phlegm, urine, and blood to find evidence of the bacteria.

How Does a Person Contract It?

This disease can be contracted by breathing in the warm mist which carries the bacteria. It is not transmitted person-to-person. Usually, 2-14 days prior to exposure, symptoms will show up. In 5% to 30% of all cases, it is fatal.
