Abstract
INTRODUCTION: Measles incidence per million populations for Marudi district was 266 in 2018. We aim to describe the Measles outbreak investigations performed at rural village of Marudi district in September 2018. No Measles cases reported from the village for past five years. METHODS: A cross-sectional study of the village population was performed. Case definition was any individual with fever and rash and either cough or coryza or conjunctivitis from Long Banyok Village, Marudi from 28 August until 02 October 2018. Active case detections and mopping up activity were performed. Clinical samples were taken for laboratory analysis. RESULTS: The overall attack rate is 1.48%.100% of the cases were children ranging from five months old to 17 years old. 67% were males and 33% were female. Symptoms were fever (100%), maculopapular rashes (100%), cough (67%), coryza (67%) and conjunctivitis (67%). 100% of the cases were categorised as lab-confirmed measles. Total 212 contacts were identified, and none had symptoms. 100% coverage for mopping up activity achieved within 1km radius. No defaulters found. The primary case from Miri urban town centre was positively identified. Transmission occurred during a funeral gathering at the village. DISCUSSION: The cases were contained within the visitors as the herd immunity among children in the rural village was strong. There is high risk of disease transmission to rural areas due to population mobility. CONCLUSION: The strategy for Marudi district is to focus on intensified vaccination activity among high risk groups.
