On 1 September the National Institute for Communicable Diseases said the 2026 rotavirus season is running. Cases have risen sharply in Pretoria. One death is on the ledger. Principal medical scientist Prof Nicola Page described the pattern: sudden vomiting, then watery non-bloody diarrhoea, then dehydration that can kill an infant. Fever in about a third to half of cases. Most children meet this virus at least once by the age of two.
Rotavirus travels faecal-oral. It peaks in the cooler, drier months. The NICD watches it through Germs-SA sites at Pelonomi, Klerksdorp/Tshepong, Red Cross Children’s Hospital, Kabokweni Clinic and Kalafong. The death is confirmed. The name of the child is not public. Do not invent one.
The shot that stops the worst of this sits on the same Road to Health card as measles and the hexavalent. That card is the part of the system that is failing.
Foster Mohale at the Department of Health put the zero-dose share at 36.3% of infants between January and April 2026. In 2017 it was 12.1%. That is a triple. First-dose coverage under one year fell from 87% in 2021 to 67% in 2025. Hexavalent coverage fell from 87% to 60.5%. The department called it a public-health emergency. The Telegraph put that warning on a global page this morning. The clinics did not get more nurses from the headline.
Measles is the other receipt. The department’s circulating total is about 3,462 laboratory-confirmed cases since January, 70.9% in children aged 1–14. The NICD sitrep earlier in the year was already higher than the political figure. Outbreaks have been named in the Western Cape, Free State, KwaZulu-Natal, the Northern Cape and other districts. Diphtheria and whooping cough have been linked to the same coverage hole.
Herd immunity is not a slogan. It is a percentage. When first-dose measles and hexavalent fall together, the virus does not wait for a commission.
Rotavirus season plus a coverage collapse. One confirmed death. Unvaccinated infants tripled in a decade. The department has announced catch-up. It has not, in the briefing that produced 36.3%, published how many extra doses actually went into arms last month.
If you have a child under five, the useful document is the Road to Health card, not the group chat. Rotavirus is on the schedule. Measles is two doses. Missing one is not “almost covered.” Dehydration from diarrhoea is the emergency in the house: fewer wet nappies, no tears, sunken fontanelle, the child who will not drink. Clinics are where this is fixed or stalls — stock, queues, whether the nurse still has the antigen.
* How many rotavirus and measles catch-up doses were given in July and August, by district?
* Which of the 52 districts are still under 95% measles coverage?
* And when will the department reconcile its 3,462 measles figure with the NICD ledger that has already run ahead of it?
