Lymphatic Filariasis is a mosquito-borne disease caused by parasitic filarial nematodes Wulchereria bancrofti, Brugia malayi and Brugia timori.In Tanzania,Wulcheleria Bancrofti is the common nematode causing disability in infected people.
The clinical manifestations of the disease are horrific, including hydrocoele, lymphoedema, orchitis, adenolymphangitis and elephantiasis. Such acute and chronic pathologies impose a significant impediment to socio-economic development, and an extremely poor quality of life.
The threshold above which mass treatment for lymphatic Filariasis is indicated in a community is Mf prevalence of above or equal to 1%. In 2004 rapid mapping for LF was completed across the whole country. Results indicated that all districts in the country are endemic. Five regions along the coast were most affected with the highest endemicity. The circulating filarial antigen (CFA) prevalence rates in these regions were up to 69%. However, in 2015,LF remapping was done in nine regions where interventions have not started. Results of this evaluations indicated that these regions would not require MDA for LF.
LF elimination efforts started in 2000 in Mafia region with mass drug distribution by using Ivermectin and Albendazole. The eligible population is all community members with the age of five years and above. These efforts were then scaled up to other endemic regions.
Up to date (2014) 16 regions have been treated with Ivermectin and Albendazole to prevent and treat against LF.
There are 6 districts of Mkuranga, Newala, Tandahimba, Lushoto, Bumbuli and Muheza where MDA for LF has been stopped. This was a result of Transmission Assessment survey conducted in these districts following more than five rounds of MDA and good coverage.
