Angiostrongyliasis

Angiostrongyliasis parasite primarily resides in rodents, particularly rats, but can also infect snails, slugs, and other intermediate hosts. Human infection occurs through ingestion of contaminated intermediate hosts or food items, such as raw vegetables or fruits, contaminated with the parasite's larvae. Once ingested, the larvae migrate to the central nervous system, causing neurological symptoms ranging from headaches and stiff neck to more severe complications such as meningitis or encephalitis. Diagnosis is often challenging due to nonspecific symptoms, but can be confirmed through laboratory tests or imaging studies. Treatment typically involves supportive care and antiparasitic medications, although severe cases may require hospitalization. Prevention focuses on proper food hygiene practices and avoiding consumption of raw or undercooked intermediate hosts. Public awareness and education are crucial in endemic regions to minimize the risk of infection and improve early detection and management of angiostrongyliasis.
