Malaria stratification in China has not been updated since 1958.
Significant changes in malaria epidemiology necessitate a revised stratification.
Purpose:
To redivide China's malaria endemic areas based on current data.
To provide a scientific basis for future malaria control strategies.
Summary:
A new malaria stratification divides China into four regions: Western (largely non-endemic), Northern (malaria eliminated/sporadic), Central (hypo- to meso-endemic), and Southern (hypo- to meso-endemic).
Mosquito vector species, malaria incidence, and geographical divisions were key indices.
Demarcation lines for non-endemic and eliminated areas were established.
Impact:
Facilitates targeted and effective malaria control interventions.
Supports resource allocation for public health initiatives.
Improves understanding of current malaria distribution in China.
