*Number of malaria service points, CHWs, and facilities reflects the status in December each year, or in May 2020. Total malaria admissions and deaths reflect the totals across all 83 study districts for the whole calendar year, or January to May (peak transmission season) for 2020. Note that since IRS is usually completed during October-January, the proportion of population receiving IRS during 2020 appears artificially low due to restriction of 2020 data to January-May only
a2020 data for January to May only, corresponds with peak transmission season
