Evaluating Thailand’s malaria reactive surveillance and response strategies for malaria elimination: a mixed-method study

Abstract

Background: Thailand aims to eliminate malaria in all provinces by 2030, where 37 out of 77 provinces have been verified as malaria-free by 2021. Thailand is accelerating its elimination activities and preventing re-establishment of malaria through implementation of the 1-3-7 reactive surveillance and response (RASR) strategy, which entails case notification within one day, case investigation within three days and case investigation survey within seven days after detecting an index malaria case. This study aimed to assess how this 1-3-7 malaria RASR strategy was implemented to understand how it may be optimised to achieve national malaria elimination goals. Methods: A cross-sectional mixed-m..
