Implementation of the 1-3-7 surveillance strategy for malaria elimination in Thailand
Objectives
The overall goal of the ‘Inform Asia: USAID’s Health Research Program’ is to promote the generation and use of evidence-based strategic information to achieve malaria elimination.
The specific objectives with regard to the 1-3-7 surveillance strategy are:
- To assess the effectiveness of the 1-3-7 approach and identify factors associated with presence of active foci.
- To outline Thailand’s experience adapting and implementing the 1-3-7 strategy, including lessons learned and success factors, in the hope that this information may be helpful for other countries considering strengthening surveillance for malaria elimination.
Thailand’s success in reducing malaria burden is built on the efficient “1-3-7” strategy applied to the surveillance system. The strategy is based on rapid case notification within 1 day, case investigation within 3 days, and targeted foci response to reduce the spread of Plasmodium spp. within 7 days. However, autochthonous transmission is still occurring in the country, threatening the goal of reaching malaria-free status by 2024.
Data from the national malaria information system were extracted from fiscal years 2013 to 2019; after data cleaning, the final dataset included 81,012 foci. A Cox’s proportional hazards model was built to investigate factors linked with the probability of becoming an active focus from 2015 to 2019 among foci that changed status from non-active to active focus during the study period.
