ANAHEIM, Calif. — Three new cases of Legionnaires’ disease have been identified in Southern California and officials are looking at the possibility there may be a source outside Disneyland, where at least 11 of the patients visited in September, according to reports.
Legionnaires’ has sickened a total of 15 people, two of whom have died. The four not connected to Disneyland lived in or had visited Anaheim, suggesting that there could be sources of infection not yet discovered, the Los Angeles Times reported on Thursday.
The disease can be spread through inhaling droplets from contaminated water sources. While many people have no symptoms, it can cause serious pneumonia and prove dangerous to those with lung or immune system problems.
Disneyland said it learned about the Legionnaires’ cases on Oct. 27 and shut down and disinfected two cooling towers where health officials believe the exposure might have occurred.
Water samples taken last week from the towers, which are part of air-conditioning systems, tested negative for the bacteria, officials at the theme park said on Wednesday.
