“South Africa has recorded 5,306 laboratory-confirmed measles cases between 29 December 2025 and 20 September 2026, according to the latest National Institute for Communicable Diseases (NICD) surveillance report published on 2 October. The report says measles cases are increasing nationwide, with 269 additional cases detected since the previous report and health authorities calling for stronger surveillance, rapid investigation of suspected infections and continued vaccination efforts.”
South Africa’s measles cases continue to rise
South Africa is facing a sustained measles challenge, with the latest national surveillance figures showing that more than 5,300 laboratory-confirmed cases have been recorded since the beginning of the current reporting period. The National Institute for Communicable Diseases (NICD), which publishes weekly surveillance information on measles and rubella, reported on 2 October 2026 that 5,306 laboratory-confirmed measles cases had been identified nationally between 29 December 2025 and 20 September 2026.
The latest figures provide an important snapshot of the country’s continuing disease burden. According to the NICD, the national surveillance system has detected an increase in measles cases nationwide. Since the previous report, 269 additional cases were detected. However, the institute cautions that the numbers can be affected by the timing of laboratory testing and the arrival of specimens from suspected cases.
The latest report is particularly significant because measles is a highly contagious vaccine-preventable disease. The continued increase in confirmed infections highlights the importance of maintaining strong childhood immunisation programmes, identifying suspected infections quickly and ensuring that people who may have been exposed receive appropriate medical attention.
Free State records the largest number of new cases
The distribution of the newly detected cases shows that transmission is occurring across all nine provinces. Of the 269 additional cases reported since the previous surveillance update, the Free State recorded the highest number, with 57 new cases.
Limpopo followed with 50 additional cases, while the Northern Cape recorded 47. KwaZulu-Natal reported 35, North West recorded 24, Gauteng 20, Mpumalanga 19, Western Cape 15 and Eastern Cape two.
These figures demonstrate that the current measles situation is not restricted to one geographical area. Instead, confirmed infections are being detected throughout South Africa, reinforcing the importance of nationwide surveillance and immunisation activities.
The latest data also follow reports from individual provinces about vaccination gaps. On 1 October, SABC News reported that the Northern Cape had recorded 767 laboratory-confirmed measles cases between October 2025 and September 2026. Provincial health authorities said investigations had linked many cases to children who had not been immunised.
The provincial experience illustrates one of the major challenges facing measles control: maintaining high vaccination coverage across communities so that the virus has fewer opportunities to circulate.
Why measles surveillance matters
Measles surveillance is an important part of South Africa’s infectious-disease monitoring system. The NICD says health professionals and public health officials should strengthen surveillance, laboratory confirmation, case reporting and contact tracing to support the country’s measles elimination goals.
Suspected measles and rubella cases should be investigated promptly. Healthcare professionals are expected to collect blood specimens for laboratory confirmation and report cases through the Notifiable Medical Conditions Surveillance System.
This process allows health authorities to establish where infections are occurring and identify potential transmission chains. It can also help authorities determine where additional public-health interventions may be necessary.
The significance of laboratory confirmation is particularly important during an outbreak because symptoms of measles can overlap with those of other infections. Confirming cases helps public-health teams understand the actual scale and geographical distribution of transmission.
Vaccination remains central to prevention
The latest surveillance report places renewed emphasis on vaccination and public awareness. The NICD says awareness campaigns should be intensified to build confidence in vaccines and address hesitancy by working with community leaders, healthcare workers and other stakeholders.
Routine childhood immunisation is one of the key tools available to prevent measles. South Africa’s public health system provides childhood vaccines through the Expanded Programme on Immunisation. Municipal health information lists measles vaccination among routine childhood immunisations, including doses during infancy and at 12 months.
The importance of maintaining vaccination coverage has also been highlighted by provincial health authorities. In September, Gauteng health officials urged parents and caregivers to ensure children remained up to date with routine vaccinations after health teams found that significant numbers of children had missed immunisations.
The concern is that gaps in immunisation can create opportunities for measles transmission. When fewer children are protected, a contagious infection can spread more easily through schools, households and communities.
Rubella remains part of the wider surveillance picture
The latest NICD report also provides an update on rubella, another contagious viral infection monitored through South Africa’s fever-and-rash surveillance system.
Between 29 December 2025 and 6 September 2026, 595 laboratory-confirmed rubella cases had been reported nationally. Unlike the measles figures, however, the latest report says no additional rubella cases had been reported since the previous update.
Rubella is often relatively mild, but it can have serious consequences during pregnancy. Infection during pregnancy can result in congenital rubella syndrome, which can cause health problems in an unborn child.
The NICD therefore says healthcare professionals should strengthen surveillance and laboratory confirmation of suspected rubella cases. For communities, the institute highlights vaccination as the main preventive measure.
The connection between measles and rubella surveillance is important because both diseases can cause fever and rash and can circulate within communities when immunity gaps exist.
Children remain an important focus
Measles prevention is particularly important for children because outbreaks can affect large numbers of young people when vaccination coverage falls.
Recent South African reports have repeatedly highlighted missed childhood vaccinations. In the Northern Cape, provincial officials said many of the children affected by the province’s measles outbreaks had not received immunisations.
Similarly, health officials in Gauteng have previously raised concerns about children missing routine vaccinations. The provincial government reported first-quarter 2026/27 immunisation coverage of 72% among children under one year, while coverage for the second dose of the measles-rubella vaccine at one year was reported at 70.7%.
These figures provide context for the national surveillance findings. Vaccination coverage varies across communities and provinces, and pockets of lower coverage can create conditions in which preventable diseases spread.
The role of early detection
Early recognition of suspected measles cases is another important element of disease control. Health professionals are encouraged to investigate suspected cases quickly, collect appropriate samples and report cases through the national surveillance system.
For communities, the latest public-health message is centered on awareness and timely engagement with healthcare services. People who develop symptoms that could indicate measles should seek professional medical assessment rather than relying on self-diagnosis.
Because measles is highly contagious, identifying cases promptly can help public-health officials investigate contacts and monitor potential transmission.
The NICD’s recommendation for stronger surveillance therefore extends beyond laboratories. It involves healthcare workers, public-health officials, communities and families working within the national disease-monitoring system.
A continuing national health challenge
The latest figures show that South Africa’s measles situation remains an important public-health issue as the country moves through the latter part of 2026.
The 5,306 confirmed cases reported through 20 September represent a substantial increase compared with earlier surveillance updates. For example, the NICD’s week-37 report recorded 5,037 laboratory-confirmed cases through 13 September. That report itself had identified 458 additional cases compared with the preceding update.
The figures demonstrate why disease surveillance needs to continue even when public attention shifts to other health concerns. Measles transmission can change geographically, and delays between specimen collection and laboratory reporting can mean that surveillance figures are subsequently updated.
The NICD therefore continues to publish weekly surveillance reports, allowing health authorities and the public-health sector to follow the national situation.
What happens next
The immediate priorities identified by the latest report include stronger disease surveillance, laboratory confirmation, contact tracing and public awareness.
For healthcare professionals, this means maintaining vigilance when patients present with symptoms consistent with measles or rubella and ensuring suspected cases are appropriately investigated and reported.
For communities, the focus is on strengthening confidence in routine childhood immunisation and ensuring eligible children receive recommended vaccines.
The latest report does not indicate that measles transmission is confined to one province. Instead, confirmed additional cases were reported in all nine provinces, with the largest numbers in the latest reporting period coming from Free State, Limpopo and Northern Cape.
That national distribution means responses must also operate across the country.
South Africa’s continuing measles challenge illustrates the importance of maintaining vaccination programmes even after diseases become less common. When vaccination coverage declines or children miss scheduled doses, communities can become more vulnerable to outbreaks.
For now, the latest NICD surveillance provides a clear picture: measles transmission remains active across South Africa, and confirmed cases continue to accumulate. Health authorities are calling for stronger surveillance and public-health action, while vaccination remains a central tool for preventing further spread.
