Dear Mayor Arakawa,

Q: The reports about Rat Lungworm Disease are very scary because the parasite-based disease can cause permanent damage. Since there are a lot of rats near where I live, I wanted to know—is it possible to contract the disease through contact with rat feces?

A: Thank you for asking this question, as we all need to stay informed about this very serious disease.

From what scientists currently know, humans do not get sick from contact with rats or their feces; instead, they can contract the disease from the third larval stage of the parasite when it is present in the bodies of slugs, snails, frogs, freshwater prawns and land crabs that are eaten raw or under-cooked.

People can become infected accidentally by eating raw produce that contains a small snail or slug or part of one, so wash, cook or freeze produce and foods carefully.

Rat Lungworm, or angiostrongyliasis, can affect the brain and spinal cord with symptoms ranging from very mild or none at all, to life-altering pain, skin tingling and sensitivity, severe headache, sensitivity to light, hallucinations, nausea and vomiting and other debilitating symptoms.
