Human and Simian Malaria in the Greater Mekong Subregion and Challenges for Elimination
In recent years malaria initiatives have increasingly shifted from malaria control to a focus on achieving malaria elimination in the Southeast Asia region. However, this region experiences unique challenges in this transition due to its distinctive malaria ecosystem (mainly related to forests) and high volume of population movement (both within and between countries). These bioenvironmental factors increase the exposure of populations at higher risk due to their close association with forest, and contributes to outdoor and residual transmission. Given that this region has also historically been the source of resistance to anti-malarial drugs, the potential spread of artemisinin resistance via global transportation routes would pose a major threat to malaria control and elimination efforts worldwide. In addition, other factors also hinder the malaria elimination goal such as importation of parasite infection, uncontrolled monkey malaria (Plasmodium knowlesi), or the fact that many countries in this region experience mixed infections where P. vivax becomes a more predominant species as overall malaria transmission decreases. This chapter addresses these challenges in detail and provide recommendations and key priorities to overcome these obstacles to accelerate efforts for achieving malaria elimination.

The Role of Adaptive Surveillance as a Core Intervention to Achieve Malaria Elimination
Adaptive surveillance systems are essential for national programmes to achieve their malaria elimination goals. Core principles of surveillance systems including accurate diagnosis and reporting of malaria cases, integration of health data across administrative levels and the need to link data to a response are well defined by international guidelines. Nevertheless, while the requirements of surveillance systems along the transmission continuum are clearly documented, the operationalization remains challenging for national programmes. Firstly, because the multi-level increase of surveillance efforts demanding real-time and case-based data as well as the capacity of the health force to trigger locally customized responses, is resource intensive and requires substantial investment. Secondly, because there is a gap in international alignment on best tools and practices on how to operationally implement these requirements. Recently, several initiatives have started to address this gap in international coordination, aiming to establish the operational guidance for elimination programmes to successfully implement adaptive surveillance systems.
