ATLANTA (AP) - Atlanta's largest hospital is investigating an
unusual increase in cases of Legionnaire's disease.
Grady Memorial Hospital diagnosed four cases of the illness in
since January 1.
Officials are investigating the possibility that the disease spread through the hospital's water or air.
A hospital spokeswoman says preliminary test results should come back Monday.
Legionnaires' disease is a bacterial infection that can cause
potentially deadly pneumonia.
The bacteria do not spread from person to person. Instead, people get it from breathing in contaminated mist or vapor.
Tainted air conditioning systems or the contaminated whirlpool spas are some of the ways the bacteria can get in the air.
Officials say about 80 beds on the hospital's 11th and 12th
floors have been taken out of service pending tests of the hospital
