Endemic diseases include dengue fever, filariasis, leishmaniasis, malaria, meningitis, schistosomiasis, and sleeping sickness. These included helminthiasis, schistosomiasis, dengue, and lymphatic filariasis. Lymphatic filariasis is also known as elephantiasis. Loa loa is the filarial nematode (roundworm) species that causes "Loa loa" filariasis. Secondary bacterial infection is often observed with lymphatic filariasis. Infections with parasitic filarial worms cause disease conditions generically known as filariasis. Other possible causative infections include aortitis, histoplasmosis, and filariasis. The antibiotic doxycycline is also effective in treating lymphatic filariasis. They are among roundworms that cause the parasitic disease filariasis. If left untreated, the infection can develop into a chronic disease called Lymphatic filariasis. The present objective of prevention is the eradication of lymphatic filariasis. Around 120million people globally are believed to be infected with lymphatic filariasis. Recently, 120 million worldwide cases of lymphatic filariasis were estimated. There is currently no licensed vaccine to prevent lymphatic filariasis. This filarial nematode is one of two that causes serous cavity filariasis in humans.
