Roundworm Infections

Filariasis is a group of parasitic infections caused by thread-like nematodes (roundworms) belonging to the Filarioidea superfamily. Lymphatic filariasis, caused by Wuchereria bancrofti, Brugia malayi, and Brugia timori, is a major contributor to the global burden of neglected tropical diseases. The parasites are transmitted through the bites of infected mosquitoes, which deposit larvae into the bloodstream. The larvae mature into adult worms that reside in the lymphatic vessels, leading to chronic lymphatic damage and lymphedema. Clinical manifestations of lymphatic filariasis include swelling of the extremities, scrotal swelling (hydrocele in males), and recurrent skin infections. The diagnosis involves detecting microfilariae in blood samples. Mass drug administration with antifilarial drugs like diethylcarbamazine (DEC) or ivermectin, combined with albendazole, is the primary strategy for controlling and eliminating filariasis. Vector control measures, such as insecticide-treated bed nets and environmental management, also play a crucial role in preventing transmission. Research efforts in roundworm infections focus on developing new antiparasitic drugs, improving diagnostic tools, and exploring novel strategies for vector control. Additionally, public health initiatives aim to integrate filariasis control into broader health programs to achieve sustainable disease elimination.
