Penemuan Mikrofilaria Brugia malayi di Wilayah yang Telah Lulus Transmission Assesment Survey (TAS-3) di Kabupaten Kotawaringin Barat Provinsi Kalimantan Tengah

Abstract

Kotawaringin Barat is a filariasis endemic area and has been undergoing mass drugs adminstration (MDA) for 5 years. The district passed third phase of Transmission Assesment Survey (TAS-3) in 2016. In the TAS-3, we found 4 children with filariasis antibodies. In this study, we performed microscopic examination of microfilaria to confirm the results of TAS-3, as well as the measurement of knowledge, attitudes, and behavior towards the treatment of filariasis. The study was conducted in Dawak Village and Sungai Bakau Village, with a total sample of 620 respondents. The results of microscopic examination are 5 respondents with Brugia malayi in their blood, consisting of 4 respondents in Dawak Village and 1 respondent in Sungai Bakau Village. The percentage of respondents who know the causes and symptoms of filariasis is very small. Although most respondents have a positive attitude towards treatment, the right treatment behavior is still very low. One respondent was found to be reinfected with B. malayi. In addition, it is suspected that there is transmission from animals to humans, but it still needs further investigation.

Prevalensi Wuchereria bancrofti Paska Pemberian Obat Pencegahan Massal Filariasis Limfatik di Wilayah Endemis Rendah Kota Pekalongan

“…Bangka Barat paska TAS-2 (B. malayi), 9 Kota Waringin Barat paska TAS-3 (B. malayi). 10 Beberapa wilayah juga melaporkan bahwa masih ditemukan positif antigenaemia pada siswa pada saat evaluasi TAS, baik yang nilainya di bawah cut of point (lulus TAS) maupun yang melebihi cut of point (gagal), di Kabupaten Agam Sumatera Barat TAS-1 (B. malayi), 11 dan di negara lain seperti Bangladesh ditemukan positif pada wilayah endemis tinggi (W. bancrofti). 12 Faktor yang mempengaruhi terjadinya penularan kembali LF (re-transmission) pada wilayah yang telah menyelesaikan POPM diantaranya adalah cakupan POPM yang rendah, 13,14,15,16 penolakan masyarakat karena reaksi efek obat, 17 metode surveilans, lingkungan (agen, vektor, dan reservoar), 18,19,20 faktor sosial demografi, serta perilaku masyarakat (perilaku berisiko dan kepatuhan minum obat).…”

“…Beberapa wilayah yang telah menyelesaikan POPM dan paska evaluasi TAS masih ditemukan nyamuk positif LF. 7,10,32 Hal ini menunjukkan bahwa keberadaan nyamuk vektor harus dikendalikan melalui kegiatan surveilans vektor. Keberlangsungan surveilans vektor dalam pre-paska POPM LF sangat dibutuhkan.…”
