Toxocara canis (Visceral larva migrans)

Toxocara canis is a parasitic helminth that infects humans through egg ingestion from dog fur, soil, or undercooked lamb or rabbit. Children are at higher risk of infection due to their tendency to play in soil or sand and put their hands in their mouths.

Symptoms may include fever, cough, wheezing, abdominal pain, and rash. In severe cases, the parasite can cause damage to the liver, lungs, or central nervous system. Treatment involves antiparasitic medications, such as albendazole or mebendazole, to kill the larvae. Corticosteroids may also be used to reduce inflammation and alleviate symptoms.
