A model of dengue transmission: determination of the threshold of transmission using ovitrap surveillance data in Sarawak, Malaysia

Abstract

Weekly ovitrap surveillance of Aedes vectors was conducted continuously in three urban areas in Kuching, Sarawak to monitor their populations. The possible application of sequential sampling technique to analyse the ovitrap data was examined. The Aedes eggs/larvae were found to exhibit a clumped distribution fitted to a negative binomial distribution model without a common K value. The sample size of ovitraps required for decision to control Aedes vectors was determined using techniques of sequential sampling and its use in dengue vector control in Malaysia was examined.
