Understanding Intestinal Angiostrongyliasis: Causes, Symptoms, and Prevention

Intestinal angiostrongyliasis is a rare parasitic infection caused by the nematode Angiostrongylus cantonensis, commonly known as the rat lungworm. This debilitating condition primarily affects the intestinal tract and can lead to various health complications. In this article, we will explore the causes, symptoms, and preventive measures associated with intestinal angiostrongyliasis.

Causes:

Intestinal angiostrongyliasis occurs when humans consume contaminated food or water containing the infective larvae of A. cantonensis. This parasite primarily infects rats, which act as intermediate hosts. Snails and slugs consume the larvae from rat feces, and humans become infected when they inadvertently ingest these infected mollusks or consume raw vegetables contaminated with them.

Symptoms:

1. Abdominal pain: One of the most common symptoms of intestinal angiostrongyliasis is abdominal pain, which can range from mild discomfort to severe cramping.
2. Nausea and vomiting: Individuals infected with intestinal angiostrongyliasis may experience nausea and vomiting, often accompanied by a loss of appetite.
3. Diarrhea: Infected individuals may develop diarrhea, which can be watery or bloody in some cases.
4. Headaches: Some patients may experience persistent headaches, which can range from mild to severe.
5. Fever: In certain cases, a low-grade fever may be present, indicating an inflammatory response to the parasite.
6. Neurological symptoms: In rare instances, intestinal angiostrongyliasis can cause neurological complications like tingling or numbness in the extremities, facial paralysis, or even meningitis-like symptoms.

Prevention:

1. Thoroughly wash and cook vegetables: Properly washing fruits and vegetables helps remove any potential snails, slugs, or their larvae. Additionally, cooking vegetables thoroughly can destroy any remaining parasites.
2. Avoid eating raw or undercooked snails and slugs: It is crucial to avoid consuming raw or undercooked snails or slugs, as they can carry the infective larvae.
3. Practice good hygiene: Regularly washing hands before meals and after handling soil or raw vegetables can help prevent infection.
4. Avoid drinking untreated water: Ensure that drinking water is safe by using filtration or boiling methods.
5. Control rodent populations: Reducing the presence of rats around human settlements can help minimize the risk of infection.
