Halzoun is a term used in the Middle East, particularly in Lebanon, to describe a throat infection caused by the parasite Angiostrongylus cantonensis. This parasitic infection, also known as eosinophilic meningoencephalitis, is characterized by inflammation of the brain and spinal cord, leading to a range of neurological symptoms.
Symptoms of Halzoun
Symptoms of halzoun typically begin within a few days to weeks after consuming infected snails or slugs. Common symptoms include:
- Headache
- Neck stiffness
- Fever
- Nausea and vomiting
- Dizziness
- Seizures
- Paralysis
Transmission of Halzoun
Halzoun is transmitted through the consumption of raw or undercooked snails or slugs that are infected with the parasite Angiostrongylus cantonensis. The parasite's life cycle involves a rat as the definitive host, and snails or slugs as intermediate hosts. When a rat consumes the parasite's larvae, they mature into adults in the rat's lungs. The adult female parasite then lays eggs, which are passed out in the rat's feces. These eggs hatch into larvae that are ingested by snails or slugs. When a human consumes an infected snail or slug, the larvae enter the human's body and travel to the brain and spinal cord.
Prevention of Halzoun
The best way to prevent halzoun is to avoid consuming raw or undercooked snails or slugs. It is also important to wash fruits and vegetables thoroughly before eating them, as they may have come into contact with infected snails or slugs.
Treatment of Halzoun
Treatment for halzoun typically involves medication to reduce inflammation and control symptoms. In some cases, surgery may be necessary to remove the parasite from the brain or spinal cord.
