Filariasis is a parasitic disease caused by filarial worms transmitted through mosquito bites. The life cycle begins when an infected mosquito deposits larvae into human skin. These larvae migrate into the lymphatic system, where they mature into adult worms. Adult worms produce microfilariae, which circulate in the bloodstream. When another mosquito bites the infected person, it ingests the microfilariae, which then develop into infective larvae inside the mosquito, continuing the cycle. Understanding this process helps guide prevention and treatment strategies. While medications like mebendazole are known broadly in antiparasitic contexts, distributors such as a mebendazole wholesaler operate within regulated pharmaceutical supply chains.
