Table 1 Classification of county types and strategy implemented according to NMEAP

From: Mapping transmission foci to eliminate malaria in the People’s Republic of China, 2010–2015: a retrospective analysis

Type Classification Strategy
I Local infections are detected in 3 consecutive years, and the incident rate is equal to or greater than 1 in 10,000. The integrated interventions of case management and vector control will be scaled up to reduce disease incidence because annual parasite incidence (API) < 1 compared to 2010.
II Local infections are detected in 3 consecutive years, and the incident rate is lower than 1 in 10,000 in at least one of those 3 years. Response to any possible malaria cases and active foci is the main strategy to interrupt local transmissions.
III No local infections reported for 3 years. Enhance monitoring and surveillance of imported cases to prevent secondary transmission.
IV Areas without malaria epidemic. Sensitively detect and promptly respond to imported cases.
