Brugia is a genus of parasitic worms belonging to the family Onchocercidae. These filarial nematodes primarily infect humans and are transmitted through the bites of infected mosquitoes. The most notable species within this genus is Brugia malayi, which is a major cause of lymphatic filariasis, a disease that can lead to severe swelling and disability. Infection with Brugia can result in a range of symptoms, including fever, swelling, and inflammation of the lymphatic system. Preventive measures focus on controlling mosquito populations and administering medications to affected individuals. Effective treatment can help manage symptoms and reduce the risk of transmission.
