Malaria Micro Stratification Report 2018: Malaria risk stratification identifies geographical areas that are at a potential risk of malaria transmission based on the recent malaria burden, receptivity characteristics, and the potential vulnerability of the area to malaria. Malaria risk stratification is a prerequisite for a rational targeted intervention and an essential step for an effective and efficient resource mobilization. In the past, malaria risk stratification in Nepal was conducted at the district level and the population of the district was defined as the population at risk of malaria. But, with the substantial decline in the burden of malaria during the past decades, and the evidence that only few Village Development committees (VDCs) within the district reported malaria cases while other VDCs remained free of malaria; there was a need to conduct the study at a more basic level such as wards.
Malaria stratification was conducted in 2016 and the study provided the strategic evidence of malaria transmission at the wards level and the population of the ward was defined as the population at risk of malaria. The external malaria program review in 2016 recommended an annual updated malaria risk stratification based on the most recent data. Besides, the review recommended that since the country is moving towards elimination; the weightage allotted to disease burden should be allotted more weight. Malaria risk stratification 2018 was tailored to suit the changing epidemiology of malaria in the country and to ensure appropriate weightage is allotted to key determinants of malaria transmission as recommended by external malaria program review. Malaria data from last three years reveal that even within Rural Municipalities or Municipalities, malaria is concentrated within some wards while other wards remain relatively free of malaria. In these settings, transmission is typically sufficiently low and spatially heterogeneous to warrant a need for estimates of malaria risk at a community level, the wards.
In order, to refine the risk stratification at the community level and thereby define the total population at risk of malaria; malaria risk micro- stratification was conducted at the wards level of Rural Municipality or Municipalities. The methodology used recent malaria burden data supplemented by information on the spatial distribution of key determinants of transmission risk including climate, ecology, and the presence or abundance of key vector species and vulnerability in terms of human population movement.
