ABSTRACT
The global malaria situation remains a massive public health crisis. There are over 280 million cases and roughly 610,000 deaths annually worldwide. In 2018, Malaysia achieved a monumental public health milestone: zero local cases of human malaria. This success was hard-won through decades of relentless entomological surveillance, vector control and community cooperation Despite this achievement, a comprehensive spatial risk stratification framework integrating vector receptivity and population vulnerability remains unavailable. This study aims to geographically map areas based on their Malaria Re-introduction Risk (MRR). Data from 2,775 locations across Malaysia between 2019 and 2023 were analyzed using the Ministry of Health's MyEntoPest database. By assessing each area's receptivity, R (the presence and abundance of competent Anopheles vectors) and vulnerability. V (the influx of potentially infected populations), we calculated the specific MRR for each site (MRR=Rx V) Locations were then categorized and mapped as Low (MRR-12), Medium (MRR=3.4), or High (MRR-63) using GIS software. Over the five-year period, the vast majority of evaluated locations remained at Low risk for re-introduction. Furthermore, temporal mapping revealed a consistent, nationwide decline in High-risk areas. This reduction demonstrates that Malaysia's angoing vector control and surveillance strategies are effectively mitigating transmission risk. Ultimately, sustained entomological surveillance and vector control remain critical to prevent malaria re-introduction despite low risks
