 Filariasis | AHealthyMe.com
Filariasis is characterized by fever, chills, headache, and skin lesions in the early stages and, if untreated, can progress to include gross enlargement of the limbs and genitalia in a condition called elephantiasis.
Filariasis is occasionally found in the United States, especially among immigrants from the Caribbean and Pacific islands.
In cases of lymphatic filariasis, the most common form of the disease, the disease is caused by the adult worms actually living in the lymphatic vessels near the lymph nodes where they distort the vessels and cause local inflammation.

Among the other species, Loa loa and Mansonella streptocerca are found in Africa; Mansonella perstans occurs in both Africa and South America; and Mansonella ozzardi occurs only in the American continent.

Part of problem you're facing is that filariasis is often used as a synonym for lymphatic filariasis.
"Loa loa" and "river blindness" (onchocerciasis) and a bunch of other human filariasis that can also be categorized under "filariasis." But in terms of global distribution and amount of disability that it causes in other countries, lymphatic is much greater global health problem than the others.

Background: Filariasis is a disease group affecting humans and animals that is caused by nematode parasites of the order Filariidae, commonly called filariae.
Returning missionaries and Peace Corps volunteers are at particular risk for lymphatic filariasis and onchocerciasis because of the long prepatent period and relatively high intensity of exposure required between exposure to infective insect bites and the development of sexually mature adult worms.

It should be possible to exploit this fact to develop tools to monitor the progress of the global program to eliminate lymphatic filariasis (LF); however, assays based on parasite extracts suffer from a number of limitations, including the paucity of parasite material, the difficulty of assay standardization and problems with assay specificity.
For mapping the distribution of lymphatic filariasis, rapid antibody tests may provide acceptable sensitivity, depending on the geographic area where the mapping is to be done, but the potential for problems with specificity (both in distinguishing past exposure from present infection as well as differentiating filarial from non-filarial infection) still remains.
At this point, it is not clear what antibody prevalence should be considered an indication to initiate mass treatment; no attempt was made in this study to distinguish between antibody responses associated with active infection and those triggered by exposure [24,25].
