Angiostrongyliasis due to Parastrongylus cantonensis: A Rare but Serious Disease

Angiostrongyliasis, also known as rat lungworm disease, is a rare parasitic infection caused by the roundworm Parastrongylus cantonensis. This disease primarily affects humans and animals, particularly rodents and mollusks. While cases of angiostrongyliasis are relatively uncommon, it is essential to understand the risks and preventive measures associated with this condition.

Symptoms and Transmission

The symptoms of angiostrongyliasis can vary depending on the severity of the infection. In mild cases, individuals may experience headaches, mild nausea, and abdominal pain. However, in severe cases, symptoms can include a stiff neck, high fever, blurred vision, and even neurological complications.

The primary mode of transmission for angiostrongyliasis is through the consumption of infected intermediate hosts, such as snails, slugs, or freshwater shrimp. These hosts become infected by ingesting the larvae of P. cantonensis, usually found in contaminated vegetation or water sources. Humans can become infected by consuming raw or undercooked intermediate hosts or by accidentally ingesting tiny snails or slugs present on fruits, vegetables, or other food items.

Prevention

1. Avoid eating raw or undercooked intermediate hosts, including snails, slugs, and freshwater shrimp.
2. Thoroughly wash fruits and vegetables before consumption, especially those that may have come into contact with snails or slugs.
3. Properly store food to prevent contamination by snails, slugs, or their larvae.
4. Be cautious while handling and cleaning snails or slugs, as direct contact can lead to infection.
5. Ensure proper hygiene practices, such as washing hands thoroughly after working in the garden or handling potentially contaminated items.
6. Be aware of the risk factors associated with angiostrongyliasis, particularly in regions where the disease is prevalent.

Conclusion

Angiostrongyliasis due to Parastrongylus cantonensis is a serious disease that requires attention and preventive measures to avoid infection. By following the necessary precautions, such as cooking food thoroughly, properly washing produce, and practicing good hygiene, individuals can significantly reduce their risk of contracting this rare but potentially severe illness. If you suspect you may have angiostrongyliasis or experience any concerning symptoms, it is crucial to seek medical attention promptly.
