At least 19 cases of typhoid have been reported in South Africa this month alone but City Press reports that despite the increase in confirmed cases almost every day, health experts have assured South Africans there is no typhoid outbreak.
Professor Lucille Blumberg, head of the epidemiology division at the National Institute for Communicable Diseases, explained that it is a seasonal increase that happens every January. “We see a number of typhoid cases every month, and those reported thus far neither represent an unexpected increase nor an outbreak. The distribution of cases across the provinces is also in keeping with expected trends,” she said.
“Typhoid is endemic to South Africa and about 100 cases are reported every year. An increase in typhoid cases can be expected at this time of year, on account of seasonal changes or after people have acquired typhoid during their travels in December.”
Typhoid fever is an illness caused by a bacteria called salmonella. It is transmitted when a person comes into contact with food or water that is contaminated with faecal matter, or comes into contact with someone infected with typhoid.
Cross-contamination usually occurs where there is poor sanitation and poor hygiene related to food preparation, or where drinking water is drawn from informal water sources.
Symptoms include fever, nausea, loss of appetite, headache, constipation or diarrhoea, small rose-coloured spots on the chest and an enlarged spleen or liver.
The report says of the 19 confirmed cases of typhoid, 10 have been reported in Gauteng. An investigation by the National Institute for Communicable Diseases has found that these cases are not linked to each other – except for two siblings who contracted the disease. At least half of the sufferers travelled to an area where typhoid is endemic, like southern Africa, within the month preceding their diagnosis.
Blumberg commended the Gauteng department of health for its swift reaction in identifying and treating typhoid. However, she noted it was likely that more cases would be reported in the next few weeks as more people return to South Africa from their festive travels in other countries. “Every case reported will be investigated timeously by health officials to confirm the likely source and ensure the health of the public,” she is quoted in the report as saying.
“Healthcare workers at clinics and hospitals are on the lookout for cases of typhoid. They will also ensure other conditions that present with similar signs and symptoms (such as malaria) are appropriately diagnosed and treated.”
Three cases of typhoid fever have been reported in the Western Cape, the provincial health department said, reports The Times. Two of the patients were children, both girls aged 9 and 10, in the Cape Town area. The third patient was a 52-year-old man from the Cape Winelands, said department spokesperson Mark van den Heever.
Some of them had travelled to affected areas including Zimbabwe. The first case was identified on 10 January and the latest one on 20 January.
