Ntchisi Maps

Population, PLHIV and Travel Times

Malawi Overview Map

Each pixel on the map corresponds to an area of 1km x 1km. Below we display a map of Malawi with some general information:

  • Population: population density using the WorldPop population density map, adjusted to the 2018 census numbers.
  • PLHIV: gridded prevalence estimates of the number of people living with HIV (“PLHIV density estimates”).
  • HIV Prevalence: estimated gridded HIV prevalence.
  • Geographical distance: direct distance (in km) to the closest ART facility.
  • Walking time: estimated travel time (in minutes) to the closest ART facility at a given pixel.

Additionally, it is possible to add markers with facility locations to the map:

  • ART Facilities: health facilities that provide ART services and had at least one patient on ART in 2020 (based on the DHA-MIS database).
    • “Private for profit” facilities are excluded from the analysis.
    • The number of ART patients in Q3/2020 is provided in the brackets.
  • Non-ART Facilities (Static): other (nonprofit) health facilities that do not currently provide ART facilities. (These include facilities that have indicated that they have capacity to provide ART services).

Time Thresholds

By comining the travel time maps with the gridded PLHIV prevalence, the number of PLHIV that is not reached within a certain time limit or distance (km) is computed. This is visualised in the below two maps, stratified by geographical distance and walking time.

Example interpretations:

  • Walking 15 minutes: this gives a map of the regions with PLHIV for which the closest facility is more than 15 mintues (walking time) away.
  • 5km distance: this gives a map of the regions with PLHIV for which the closest facility is more than 5km (geographical distance) away.

TA analysis

To support the analysis, we have computed the proportion and number of PLHIV that are not reached within a given time or distance. Higher percentages correspond to a larger proportion of PLHIV that is not reached within the relevant area.

Candidate Facilities (60 Minutes)

Below we provide proposed facilities for scaling-up activities, illustrated on the maps. Green areas indicate additional PLHIV that can be reached through the proposed facilities within 60 minutes. Note: facility labels were aligned to district reports that were disseminated.
