Filarioidea is a superfamily of parasitic roundworms, commonly known as filarial worms. They primarily infect mammals, including humans, and are transmitted through the bites of infected insects, such as mosquitoes and blackflies. These worms can cause various diseases, including lymphatic filariasis and river blindness. The life cycle of Filarioidea involves multiple stages, including larval and adult forms. Once inside a host, they can reside in tissues, blood, or lymphatic systems, leading to significant health issues. Effective prevention and treatment strategies are essential to control the diseases caused by these parasites.
