Operational strategies to achieve and maintain malaria elimination.
Bottom Line: However, many countries considering elimination nowadays have high intrinsic transmission potential and, without the support of a regional campaign, have to deal with the constant threat of imported cases of the disease, emphasising the need to revisit the strategies on which contemporary elimination programmes are based.This approach needs appropriate treatment of both clinical cases and asymptomatic infections, combined with targeted vector control.Elimination will thus additionally need identification and treatment of incoming infections before they lead to transmission, or, more realistically, embarking on regional initiatives to dry up importation at its source.

Mentions: Passive case detection involves a system in which data are routinely received by a central health authority based on a set of rules and laws that need a health-care provider or health facility to report some diseases or disorders on an ongoing basis and at specific intervals (weekly, monthly, yearly).29 During the GMEP, health systems were generally considered to have little geographical coverage and thus generally to be insufficient for surveillance for elimination.27,30,31 Additionally, apart from limitations related to the precision of the diagnostic methods and completeness of treatment, passive case detection has other inherent weaknesses in detection of all new infections in the population (figure 1). For Zanzibar, taking into account the factors shown in figure 1, passive case detection is estimated to identify at best 40% of all new infections.14
