Diagrams of malaria control stratification areas and strategies for a malaria-affected province of Thailand. Malaria transmission area (perennial A1 and periodic A2) regularly occurs with indigenous malaria cases, while in transmission risk area (high-receptive B1 and low-receptive B2) introduced cases with a known infection orgin. With the absence of vectors and incidence for >3 consecutive years of control, the malaria-free zone targeted by the NMCP becomes pre-integrated and integrated into the basic health services in the province. Vector control strategies include IRS (regular and special spraying for A1/A2 as focal for B1/B2) and ITNs)/LLINs. Malaria chemotherapy focuses on both active (ACD) and passive (PCD) case detections, radical treatment (RT), follow-up treatment (FT), case investigation (CI) and foci investigation (FI). The ACD includes mobile malaria clinics (MMC), mass blood surveys (MBS), special case detection (SCD), case investigation surveys (CIS), rapid diagnostic testing (RDT) and ACT through malaria posts, as in the PCD, location and personnel aid the effort, such as the malaria clinic (MC), hospital (H), health center (HC), village health volunteer (VHV) and village malaria volunteer (VMV). For the behavior objective, strategic approaches employ public relations (PR), health education (HE) and community participation (CP). This NMCP management encompasses supervision (S) and monitoring and evaluation (ME) systems, both epidemiological (EP) and entomological (ET). At the household level, such malaria villagers (A) inhabiting transmission risk areas on rubber plantations (B) in Prachuap Khiri Khan Province that were covered by IRS (2007–2010) and ITNs/LLINs (2008–2010) were recruited into the study.
