In this area, the disease is considered endemic. A study conducted by the Research Foundation in Tropical Diseases and Environment in 2002 had a sample of 1458 persons, spanning 16 different villages, and found Loa loa presence in these villages ranging from 2.22 to 19.23% of the population. The disease was found to be slightly more prevalent ...
