The clinical manifestations of filariasis caused by the two filarians are very similar. The acute stage is recurrent lymphangitis, lymphadenitis and fever, and the chronic stage is lymphedema and elephantiasis, which seriously endanger the health and economic development of residents in the epidemic area.

It is better to use mosquito net in mosquito season; When working outdoors, pay attention to apply anti mosquito oil, mosquito repellent and other repellents on the exposed skin, and use cotton thread to soak 701 anti mosquito oil to make anti mosquito net on the head. 2. In summer, more than 95% residents were required to take blood; Early detection of patients and carriers, timely cure, not only to ensure people's health, but also reduce and eliminate the source of infection. In winter, the patients with positive microfilariae or negative microfilariae but with history and signs of filariasis were given general treatment.
