"On October 27, we learned from the Orange County Health Care Agency of increased Legionnaires' disease cases in Anaheim".

Disneyland in Anaheim have shut two water towers following Legionnaires' cases. Jessica Good, a spokeswoman for the Health Care Agency confirmed, Wednesday, that Disney provided updated test results to the agency showing that there was no bacteria in the cooling towers after the water in them was sanitized November 4.

Legionella bacteria can cause a respiratory illness and pneumonia, especially in older individuals with prior health conditions.Typical sources of the bacteria are improperly sanitized spas, indoor and outdoor fountains, showers, and cooling towers - used commonly as part of air conditioning systems in large spaces. Eleven of those visited Disneyland in September.

The bacteria are common in natural water systems, such as lakes, as well as cooling towers.

'Negative results mean that the towers do not pose a current ongoing risk for transmission of Legionella, ' said Jessica Good, a spokeswoman for the Orange County Health Care Agency.

The infection is not spread person to person and those with the disease are not considered infectious. The Los Angeles Times reports that two patients have died, but neither of these visited Disneyland.

Acute bilateral pneumonia (legionnairesÕ disease caused by Legionella pneumophila), seen on a frontal chest x-ray.

Symptoms generally develop within 2 to 10 days of exposure and include fever, chills, muscle aches, and headaches. Good told the Orange County Register the agency is working with Disney on procedures to bring the towers back into operation. Health officials said two of the three new cases involved individuals who visited Disneyland.

But officials are also focusing on the four patients who didn't visit the park as they track the source of the outbreak.

All contracted Legionnaires' disease while staying at the hotel and there are more than two dozen other possible cases being investigated.

But a key question remains unanswered: How did four people who had not visited Disneyland become infected?
