The first field-friendly test for CFA (the ICT Filariasis Test, produced by ICT Diagnostics, Balgowah, NSW, Australia) was marketed in 1997 .
Filariasis is an infection caused by a parasitic worm and is transmitted by insect-bites. Treatment of lymphatic filariasis in adults and children > 18 months of age involves either a 1 day or 12 day treatment course of DEC (6mg/kg/day). The worms transferred from the mosquito, move through the skin, and travel to lymph vessels, where they grow into adults. For increased sensitivity, concentration techniques can be used.Serologic techniques provide an alternative to microscopic detection of microfilariae for the diagnosis of lymphatic filariasis. Other symptoms include fever, pain and swelling of lymph glands, headache, and inflammation of the lymph drainage areas, swelling of the scrotum, skin rashes and blindness. Filariasis is a disease group affecting humans and animals, caused by filariae; ie, nematode parasites of the order Filariidae. Avoiding mosquito bites is another form of prevention. Saving Lives, Protecting People FIL : The filariae are parasitic nematodes (roundworms) that cause significant human morbidity in tropical regions worldwide. Copyright NDTV Convergence Limited
The standard method for diagnosing active infection is the identification of microfilariae in a blood smear by microscopic examination. Circulating filarial antigen is a standard test for diagnosing Wuchereria bancrofti infections. There are eight different types of this worm, out of which three are responsible for causing the disease: Wucheria bancrofti and Brugia malayi cause lymphatic filariasis, and Onchocera volvulus causes onchocerciasis (river blindness). These mosquitoes usually bite between the hours of dusk and dawn. One day treatment is generally as effective as the 12-day regimen. When a mosquito bites an infected person, microscopic worms circulating in his blood enter and infect the mosquito. The finger prick test draws blood from the capillaries of the finger tip; larger veins can be used for blood extraction, but strict windows of the time of day must be observed. DEC (Diethylcarbamazine) provocative test (2mg/Kg): It is somewhat impractical to obtain sample blood from a patient at late night. The adult worms mate and release millions of microscopic worms into the blood. This disease spreads from person to person by mosquito bites. Use mosquito repellents on the exposed skin. CDC twenty four seven. An adult worm lives for about seven years. The skin becomes thick and rough and the increase in the size and weight of the affected parts lead to disability.

These worms then pass to the other person when this infected mosquito bites him. Filariasis is usually diagnosed by identifying microfilariae on Giemsa stained, thin and thick blood film smears, using the "gold standard" known as the finger prick test. The test is a qualitative, point-of-care diagnostic tool that detects Wuchereria bancrofti in human blood serum or plasma. In case of elephantiasis, one needs to take a yearly dose of medicine that kills the microscopic worms in the blood. Antihistamines or corticosteroids can decrease allergic reactions. It is more prevalent in the tropical areas of Africa, Asia, Central and South America. The treatment of filariasis consists of using medicines that kill the worms combined with the treatment to relieve the symptoms. After consuming DEC, microfilariae enter into the peripheral blood in … Filariasis is an infection caused by a parasitic worm and is transmitted by insect-bites. Filariasis can be diagnosed by conducting a blood test that directly shows the presence of worms. Patients with active filarial infection typically have elevated levels of antifilarial IgG4 in the blood and these can be detected using routine assays.Because lymphedema may develop many years after infection, lab tests are most likely to be negative with these patients.For more information about laboratory diagnosis of filariasis, see the DPDx website:To receive email updates about this page, enter your email address:For Healthcare Providers, Emergency Consultations, and General Public.Centers for Disease Control and Prevention. One may keep the swelling from getting worse by: Progression of the disease often causes enlargement of the legs resulting in a condition called elephantiasis or lymphatic filariasis.
