California officials probe source of Legionnaires' cases

ANAHEIM, Calif. (AP) — 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 there could be sources of infection not yet discovered, the Los Angeles Times reported 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.
