Malaria in South Africa is seasonal and primarily occurs in the Limpopo, Mpumalanga, and KwaZulu-Natal Provinces. Malaria risk and receptivity are dependent on the presence and density of vector mosquito populations. Consequently, this report provides a concise overview of the vector surveillance conducted in 2022 by the provincial malaria control entomology teams, in collaboration with various partner institutions.
Routine surveillance in 2022 revealed the presence of four malaria vector species with varying relative densities in the malaria-endemic provinces. These contribute to ongoing residual malaria transmission in South Africa. The surveillance data by province and district/municipality supports the ongoing implementation of an insecticide-based vector control strategy in conjunction with other techniques.
The Public Health Bulletin South Africa (PHBSA) is a quarterly publication that provides information on surveillance activities that enable effective monitoring of rates and distribution of diseases, detection of outbreaks, monitoring of interventions, and predicting emerging hazards.
