Abstract

Since 2002 Indonesia has implemented the Mass Drug Administration (MDA) in regencies/cities that are endemic for lymphatic filariasis. The success of regencies/cities in MDA after 5 years of implementation can be known through the TAS (transmission assessment survey). In 2017 an evaluation study was conducted to determine the failure and success of elimination of filariasis from epidemiological aspects (host, agent, environment) in 12 regencies endemic to zoonotic malayi filariasis who have passed TAS-1, TAS-2, and TAS-3. Evaluation study was carried out using finger blood sampling methods for residents, blood collection in reservoirs (long-tailed monkeys, cats and dogs) and vector mosquito capture. Finger blood test results on residents in 12 regencies: 3 regencies that have passed TAS-1 still found positive microfilaria populations, namely: Pasaman Barat (0.9%), Kuantan Singingi (0.2%), and Hulu Sungai Utara (0, 2%). As well in the 3 regencies that have passed TAS-3, namely: Bangka Barat (0.6%), Belitung (1.2%), and Kotawaringin Barat (0.8%). Results of blood tests on the reservoir, were found to be positive for B. malayi in house cats in the regencies of Pasaman Barat, Pelalawan, and Kotawaringin Barat; long-tailed monkeys in Belitung and Kotawaringin Barat regencies; and dogs in Kotawaringin Barat regency. The mosquito vectors that were caught and tested positive DNA for microfilaria larvae based on PCR examination were Culex vishnui, Culex quinquefasciastus, Mansonia dives, Mansonia uniformis, Anopheles karwari, Anopheles karwari, Aedes aegypti, Aedes cancricomes, Aedes linneatopenis, and Armigeres kucingensis in the Pesisir Selatan, Pasaman Barat, Kuantan Singingi, Bangka Barat, Belitung, and Hulu Sungai Utara regencies. From the results of the study, even though an area has passed the TAS, transmission of the disease still occurs because of the presence of microfilaria in the reservoir and filaria larvae in mosquitoes. It is recommended that regencies that have passed the TAS continue to carry out active surveillance of vulnerable populations exposed in endemic villages.
