ATLANTA — The Sheraton Atlanta has closed while the Georgia Department of Health, along with the Fulton County Board of Heath investigates reported cases of Legionnaires' disease there.

Legionnaires' disease is a serious type of pneumonia caused by bacteria known as Legionella.

According to the Centers for Disease Control and Prevention, Legionnaires' disease can cause pneumonia symptoms including cough, shortness of breath, muscle aches, headache and fever. 

People can catch the disease by inhaling the bacteria in a public place. It can't be passed by skin from person to person 

"It’s usually in the air, in water droplets like a mist that you might come across from air conditioner, the shower, a spa, something like that," said Dr. Sujatha Reddy.

Doctors use chest x-rays or physical exams to check for pneumonia. 

While Legionnaires' disease is serious, it can be treated with antibiotics. Most people who get sick need hospitalization, but make a full recovery.
