Two new cases of Rat Lungworm Disease confirmed on the Big Island Wednesday.

According to the Department of Health, two adults have contracted the disease, one is a visitor who was on vacation last year.

The visitor became sick in late December and was diagnosed and hospitalized after returning home. That person has since recovered. 

The second was a East Hawaii resident who became ill in January then was hospitalized in early February.

The Department of Health is conducting an investigation into the possible sources of infection.

The disease is spread by ingesting a snail or slug infected with the parasite. 

The Department recommends avoiding handling them without gloves, and washing all fruits and vegetable thoroughly before eating.
