Lymphatic filariasis
Einstein Health Glossary
ICD 10 - B74
What is lymphatic filariasis?
Elephantiasis, also known as lymphatic filariasis, is a tropical parasitic disease that affects the lymph nodes and lymphatic vessels. It is transmitted by mosquitoes infected with the Wuchereria bancrofti worm, which is passed on through the bite of a Culex mosquito carrying its larvae.
Symptoms
Most cases of lymphatic filariasis are asymptomatic. Rare and severe cases may cause swelling in the legs, arms, and genital organs, as well as increase the risk of frequent bacterial infections that harden and thicken the skin.
Causes
Lymphatic filariasis is caused by the Wuchereria bancrofti worm, which is transmitted through the bite of an infected mosquito.
Diagnosis
In addition to analyzing symptoms, the diagnosis of lymphatic filariasis involves blood tests to identify the presence of the parasite in the body.
Prevention Method
Lymphatic filariasis is prevented by controlling its vectors—mosquitoes—in areas where the disease is endemic. This should be done using insecticides, mosquito nets, and by eliminating standing water deposits.
Treatment
Lymphatic filariasis is treated with medications that kill the parasite responsible for the disease. Any complications may require specific care.
Duration
Since many cases of lymphatic filariasis are asymptomatic, the disease may go undiagnosed for years. Once identified, treatment lasts about two weeks.
Is it contagious?
Lymphatic filariasis is not contagious between humans. Transmission occurs through the bite of infected mosquitoes, which are currently limited to a few regions in Brazil.
Can it be contracted more than once?
It is possible to contract lymphatic filariasis more than once.
