Angiostrongyliasis, also known as rat lungworm disease, is a rare and potentially serious infection caused by a parasitic worm. The parasite is most commonly found in rats, but can also be found in snails, slugs, and other animals.

Humans can become infected by consuming undercooked or raw snails, slugs, or contaminated produce, or by accidentally ingesting contaminated soil or water. Symptoms of angiostrongyliasis may include fever, headache, neck stiffness, nausea, and vomiting, although some people may not experience any symptoms at all.

Treatment for angiostrongyliasis typically involves managing symptoms while the body fights off the infection. In severe cases, hospitalization may be required. Prevention is key, and measures such as thoroughly washing produce and properly cooking food can help reduce the risk of infection.
