Moving toward Malaria Elimination in Botswana

elimination countriesThe just concluded 2015 Global Health Conference in Botswana, hosted by Boitekanelo College at Gaborone International Convention Centre on 11-12 June provided us a good opportunity to examine how Botswana is moving toward malaria elimination. Botswana is one of the four front line malaria elimination countries in the Southern African Development Community and offers lessons for other countries in the region. Combined with the 4 neighboring countries to the north, they are known collectively as the “Elimination Eight”.

The malaria elimination countries are characterised by low leves of transmission in focal areas of the country, often in seasonal or epidemic form. The pathway to malaria elimination requires that a country or defined areas in a country reach a slide positivity rates during peak malaria season of < 5%.

pathwayChihanga Simon et al. provide us a good outline of 60+ years of Botswana’s movements along the pathway beginning with indoor residual spraying (IRS) in the 1950s. Since then the country has expanded vector control to strengthened case management and surveillance. Particular recent milestones include –

  • 2009: Malaria elimination policy required all cases to be tested before treatment malaria elimination target set for 2015
  • 2010: Malaria Strategic Plan 2010–15 using recommendations from programme review of 2009; free LLINs
  • 2012: Case-based surveillance introduced

The national malaria elimination strategy includes the following:Map

  • Focus distribution LLIN & IRS in all transmission foci/high risk districts
  • Detect all malaria infections through appropriate diagnostic methods and provide effective treatment
  • Develop a robust information system for tracking of progress and decision making
  • Build capacity at all levels for malaria elimination

Botswana like other malaria endemic countries works with the Roll Back Malaria Partnership to compile an annual road map that identifies progress made and areas for improvement. The 2015 Road Map shows that –

  • 116,229 LLINs distributed during campaigns in order to maintain universal coverage in the 6 high risk districts
  • 200,721 IRS Operational Target structures sprayed
  • 2,183,238 RDTs distributed and 9,876 microscopes distributed
  • While M&E, Behavior Change, and Program Management Capacity activities are underway

Score cardFinally the African Leaders Malaria Alliance (ALMA) provides quarterly scorecards on each member. Botswana is making a major financial commitment to its malaria elimination commodity and policy needs. There is still need to sustain high levels of IRS coverage in designated areas.

Monitoring and evaluation is crucial to malaria elimination. Botswana has a detailed M&E plan that includes a geo-referenced surveillance system, GIS and malaria database training for 60 health care workers, traininf for at least 80% of health workers on Case Based Surveillance in 29 districts, and regular data analysis and feedback.

M&E activities also involve supervision visits for mapping of cases, foci and interventions, bi-annual malaria case management audits, enhanced diagnostics through PCR and LAMP as well as Knowledge, Attitudes, Behaviour, and Practice surveys.

Malaria elimination activities are not simple. Just because cases drop, our job is easier. Botswana, like its neighbors in the ‘Elimination Eight’ is putting in place the interventions and resources needed to see malaria really come to an end in the country. Keep up the good work!
