Malaria testing and treatment of organized or identifiable groups arriving or returning from malaria-endemic areas: In areas approaching elimination or post-elimination settings preventing re-establishment of transmission, organized or identifiable groups arriving or returning from malaria-endemic areas can be tested and treated soon after entry to reduce importation of malaria. Relatively easy access to these groups within a short time after entry is required for this strategy to be feasible and acceptable. This strategy may be particularly critical to areas in post-elimination that are working to prevent reestablishment of transmission.
