angiostrongyliasis的意思|示意

Angiostrongyliasis is a vector-borne parasitic disease caused by an infection of Angiostrongylus cantonensis or other closely related species of Angiostrongylus. It is also known as rat lungworm infection or eosinophilic meningitis. The disease is found in areas where rodents are abundant, especially in tropical and subtropical regions.

Angiostrongyliasis is primarily a zoonotic disease, meaning it is spread from a non-human animal to a human. It is typically transmitted by rodents, such as rats, but can also be spread through other carriers, such as snails and freshwater shrimp. The disease can also be contracted from infected humans.

The most common symptom of angiostrongyliasis is a headache that may be accompanied by nausea and a stiff neck. Other symptoms may include fever, fatigue, muscle and joint aches, and eye pain. Some people may also experience confusion, loss of balance, and difficulty walking. Severe cases may lead to seizures or coma.

Diagnosis of angiostrongyliasis is typically made through a combination of clinical and laboratory tests. Blood tests may be used to look for antibodies specific to the parasite, and to rule out other diseases. Imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) may be used to look for inflammation in the brain or spinal cord.

Treatment of angiostrongyliasis usually involves the use of antiparasitic medications, such as albendazole and mebendazole. Antibiotics may also be prescribed. In severe cases, the patient may require hospitalization and management of symptoms.

Prevention of angiostrongyliasis is based on avoiding exposure to the parasites. People should avoid consuming raw or undercooked snails, freshwater shrimps, and rodents. Proper sanitation and rodent control is also important. People should avoid swimming in infested water and use insect repellent when outdoors.
