Size estimation and service mapping in Zambia

Harm reduction is new in Zambia. Mainline was asked to estimate how many people inject drugs in the country and to map the already existing harm reduction and HIV services for people who use drugs. Based on this information, we drafted practical service guidelines.

In doing so, Mainline hopes to have contributed to the introduction of harm reduction in Zambia.  

The assignment

In the past four months, Mainline has:

  • estimated the number of people who inject drugs in the cities of Kabwe, Kitwe and Solwezi
  • mapped the existing harm reduction and HIV services available to people who inject drugs
  • designed guidelines to facilitate the introduction of harm reduction services
The results
The results of the size estimate and the service mapping are summerised in a Factsheet. The service guideline is available upon request.
