Dear User,
Thank you for your question. In 2013 there were two surveys conducted in Sierra Leone, a Demographic and Health Survey (DHS) and a Malaria Indicator Survey (MIS). If you applied for dataset access on The DHS Program website you are looking at the DHS dataset which did not collect parasitemia data. The DHS Program only offered technical assistance to the MIS survey and is not authorized to distribute the dataset. If you would like to analyze the MIS dataset you will need to contact the National Malaria Control Program (NMCP) or Catholic Relief Services (CRS) directly to obtain dataset access.
