“South Africa is grappling with a growing measles outbreak, with thousands of confirmed cases across multiple provinces, primarily affecting children. The Department of Health and NICD are intensifying vaccination efforts to achieve 95% coverage and prevent further spread.”
South Africa is currently experiencing one of its most significant public health challenges in recent years: a rapidly escalating measles outbreak. The National Institute for Communicable Diseases (NICD) has confirmed 2,476 laboratory cases between December 2025 and June 2026, with additional infections reported since late June. This surge has prompted urgent calls for expanded vaccination campaigns, particularly in provinces with historically low coverage.
Epidemiological Trends
- Most affected age group: Children aged 5–9 years, followed by those under five.
- Adult cases rising: Over 17% of infections occurred in people older than 15, highlighting immunity gaps in older populations.
- Provincial hotspots: Free State reported the highest number of new cases, followed by Western Cape and Gauteng.
This distribution underscores the uneven vaccination coverage across provinces, with rural and underserved communities bearing the brunt of the outbreak.
Symptoms and Transmission
Measles is a highly contagious viral infection spread through airborne droplets when an infected person coughs or sneezes.
- Early symptoms: High fever, cough, runny nose, red eyes.
- Rash: Appears 7–18 days after exposure, spreading from the face to the rest of the body.
- Complications: Pneumonia, diarrhoea, and rare but fatal brain inflammation.
The severity of these complications makes measles particularly dangerous for children under five and immunocompromised individuals.
Public Health Response
The Department of Health has launched emergency vaccination drives targeting children and vulnerable groups, with the goal of achieving 95% vaccination coverage nationwide.
- Challenges: Outbreaks often occur in areas with low vaccination rates, where children are unvaccinated or under-vaccinated.
- Recent outbreaks: Reported in Free State (Fezile Dabi, Xhariep), KwaZulu-Natal (eThekwini, King Cetshwayo, uMkhanyakude), and Northern Cape (Pixley Ka Seme).
Healthcare workers are conducting door-to-door campaigns, setting up mobile clinics, and partnering with schools to reach children who missed routine immunisations.
International Context
Globally, measles remains a major health threat despite being preventable. The World Health Organization (WHO) warns that declining vaccination rates worldwide have led to resurgences in several countries. South Africa’s outbreak reflects this global trend, underscoring the importance of sustained immunisation campaigns.
Risks and Implications
- Healthcare strain: Rising cases increase demand for hospital care, especially for children with complications.
- Economic impact: Outbreaks disrupt schooling and productivity, particularly in affected communities.
- Immunity gaps: Adults contracting measles suggest lapses in historical vaccination coverage.
Expert Opinions
Dr Aaron Motsoaledi, South Africa’s Health Minister, emphasised that vaccination remains the most effective tool against measles. He urged parents to ensure their children are immunised and called on communities to support vaccination campaigns.
Conclusion
The measles outbreak in South Africa is a stark reminder of the consequences of declining vaccination coverage. With thousands of cases already confirmed and more expected, urgent and sustained public health action is critical. The success of the current vaccination drive will determine whether South Africa can contain the outbreak and prevent future resurgences.
