Abstract
Background: Globally, over 120 million people were infected with lymphatic filariasis (LF), with approximately 40 million people disfigured and incapacitated. In Asia, 63% population were at risk and 50% of people infected with LF live in Asia. India harbour 40% of the world's burden of disease. In Jerantut, Pahang, there was mass influx of Indian foreign workers to oil palm plantation in 2019. Thus, this study was done to determine the prevalence and outbreak investigation of LF among Indian immigrants in Jerantut, Pahang.
Materials and Methods: This study is a cross-sectional study done in Jerantut, Pahang between November to December 2020. The epidemiological investigations included mass night blood survey, detection of sector breeding places and entomological studies. Control measures were instituted concurrently and this included treatment of positive cases, sector control measures, personal protection and health education.
Result: A total of 12 microfilariaes (MF) positive cases were detected among 201 Indian immigrant's that undergone screening, given the prevalence of MF of 6.0%. The only MF species identified was Wuchereria bancrofti . Ranges of MF density was between 1-81 mf/60ul of blood. All positive cases were asymptomatic and 77.8% of the cases were in Jerantut for less than 2 years. All positive cases were from 5 states in India includes Bihar, Kolkatta, Telanggana, Maharashtra and Uttar Pradesh. Culex Quinquefasciatus were the majority of the vector spread in the locality. Dissection of the mosquitoes were found to be negative.
Conclusion: Considering low density of mf in blood of the cases, low density of vector mosquitoes, the transmission of LF in local community is low. However, our study stresses on the importance of close monitoring of the disease by night blood surveys and effective integrated vector control measures.
