Recommendations for public health interventions
Clinicians and public health officials are urged to strengthen measles surveillance nationally to improve case reporting, laboratory confirmation, and contact tracing to vaccinate those contacts at risk of being infected by the measles virus. All suspected measles cases should be investigated promptly, with blood specimens collected for laboratory confirmation and reported through the Notifiable Medical Conditions Surveillance System (NMCSS ).
Public awareness campaigns should be intensified to build trust in vaccines and address hesitancy by engaging with community leaders, healthcare workers, and other stakeholders to promote vaccine acceptance and participation in immunisation activities.
Update on the rubella outbreak in South Africa

The North West province continues to report a high number of cases, with 869 laboratory-confirmed cases reported from epi week 1-43 of 2025. The majority of laboratory-confirmed cases were reported in the Ngaka Modiri Molema District Municipality (753/869, 86.7%).
Recommendations for public health interventions
Rubella, also known as German measles, spreads easily through coughs and sneezes and can be dangerous for unborn babies if a pregnant woman becomes infected. The best way to prevent rubella is through vaccination with the MR vaccine that is given as part of the routine child immunisation schedule. Parents should ensure their children receive all recommended vaccine doses and take them for catch-up vaccination if any were missed.
Relevant resources, including the case definition, investigation form, and surveillance results, are available on the NICD measles page and the measles-rubella dashboard.
