The review was aimed at exploring models across Africa that could best help Lesotho succeed in its efforts to establish a case-based surveillance (CBS) system for their HIV program. Research involved looking through several sources and databases including EBSCOHOST, Google Scholar, Science Direct and PubMed. The insights of suitable models were from the following Africa countries: South Africa, Kenya, Guinea, Tanzania, Ghana, Mozambique and Zambia. The researched models focused on infectious diseases such as measles, HIVand COVID-19. The key takeaway is that setting up electronic medical records systems (EMRs) is critical as a first step for any effective CBS. Also, using unique identifiers, establishing clear data governance policies and building strong infrastructure is a necessity in making CBS work. For a successful establishment of CBS, Lesotho should adopt these strategies that can be sustainable, improve disease tracking, response and ultimately health outcomes for Basotho.

The review aims at exploring models for case-base health programs across Africa that could best help Lesotho succeed in its efforts to establish a case-based surveillance (CBS) system for their HIV program. The review involves looking through several sources and databases including EBSCOHOST, Google Scholar, Science Direct and PubMed. The insights of suitable models were from the following Africa countries: South Africa, Kenya, Guinea, Tanzania, Ghana, Mozambique and Zambia. The study articles were published within the last 10 years, specifically from 2014 to 2024. This range was used as part of their inclusion criteria to ensure relevance of the articles.
