Overview
What are the symptoms of Filariasis?
What causes Filariasis?
Filariasis is caused by parasitic organisms called nematodes or round worms. They include:
- Brugia malayi
- Brugia timori
- Loa loa
- Mansonella ozzardi
- Mansonella perstans
- Mansonella streptocerca
- Onchocerca volvulus
- Wuchereria bancrofti
Who is at highest risk?
- Repeated mosquito bites over several months to years are needed to get lymphatic filariasis.
- People living for a long time in tropical or sub-tropical areas where the disease is common are at the greatest risk for infection.
When to seek urgent medical care?
Diagnosis
The standard method for diagnosing active infection is the identification of microfilariae by microscopic examination. This is not always feasible because in most parts of the world, microfilariae are nocturnally periodic, which means that they only circulate in the blood at night. For this reason, the blood collection has to be done at night to coincide with the appearance of the microfilariae.
Serologic techniques provide an alternative to microscopic detection of microfilariae for the diagnosis of lymphatic filariasis. Because lymphedema may develop many years after infection, lab tests are often negative with these patients.
