SOUTH AFRICA PLACES LIPTERIOSIS ON HIGH SURVEILLANCE OF NUMBER OF CASES INCREASE

PRETORIA, The Department of Health has put the Listeriosis outbreak on high surveillance as 119 new cases have occurred since Dec 5, 2017 and 61 patients have died, says South African Health Minister Dr Aaron Motsoaledi.

By 5 December 2017, there were 36 people who were traced and were found to have died. “Now out of the total of 727 laboratory-confirmed cases which we know about, we were only able to trace 134 actual patients. Out of this 134 traced patients, 61 had passed on, he told a media briefing here Monday.

Since Dec 5, the department has amended the lists of notifiable diseases to include Listeriosis to allow it to track the outbreak. Prior to this outbreak, Listeriosis was not a notifiable condition. The inclusion of the disease as notifiable means health workers must report all cases of Listeriosis in terms of the reporting procedures and complete case investigation forms for patients with the disease. These forms must then be submitted to the National Institute for Communicable Diseases (NICD), said Motsoaledi.

He said the outbreak had been declared a notifiable disease it met some of the the five set criteria — the disease is contagious/communicable; rapid spread; unusual or unexpected behaviour; risk of spilling across borders; and risk of restriction to business or travel across borders.

It is now evident that Listeriosis does qualify in at least two of the criteria, which are rapid spread and unusual or unexpected behaviour.” he said, adding that the Department of Health introduced a new policy of making Listeriosis notifiable and this appeared in a Government Gazette.

The Centre for Disease Control and Prevention describes Listeriosis as a serious but treatable and preventable disease caused by the bacterium Listeria monocytogenes. It is found in soil, water and vegetation. Animal products and fresh produce such as fruits and vegetables can be contaminated from these sources.

Although anyone can get Listeriosis, those at high risk of developing the disease include newborn babies, the elderly, pregnant women, persons with weak immunity such as HIV, diabetes, cancer, chronic liver or kidney disease patients.

The age groups that are most affected are neonates � those in the first 28 days of life – and the age group 15 – 49 years. These two groups comprise 70 per cent of all cases.

The World Health Organization (WHO) South Africa representative, Rufaro Chatora, said while this outbreak is the largest recorded, he commends the government’s response.

Let me congratulate South Africa on its openness in sharing detailed information on Listeriosis. This helps South Africa and the global community at large to protect health, identify, respond and control outbreaks when they occur, in keeping with the provisions of international health regulations.

Listeriosis outbreaks have happened in many countries including the likes of France, United States and Denmark. This is, however, one of the largest recorded, said Chatora.

He said the disease is a real challenge in the health sector because of its long incubation time of between three and 70 days and cuts, across different sectors such as agriculture, farming and the food industry.

As far as the distribution in the country is concerned, Gauteng Province still has the highest reported number of cases, followed by Western Cape Province. Of the 727 cases, Gauteng has 447 (61 per cent), Western Cape 92 (13 per cent) and KwaZulu-Natal Province 51 (7.0 per cent). The remaining 19 per cent is distributed in the remaining six provinces.

Infection with listeria may result in: Flu-like illness with diarrhoea including fever, general body pains, vomiting and weakness;

Infection of the blood stream, which is called septicaemia; and Meningoencephalitis (infection of the brain).

The Health Department has advised all South Africans to practise basic food hygiene principles as outlined by the WHO which are: Keep clean. Wash your hands before handling food and often during food preparation. Don’t get tired of washing your hands. If you are handling or storing raw food, don’t touch already cooked food unless you have thoroughly washed your hands and food preparation utensils. In other words, separate raw from cooked food.

Cook food thoroughly. Never eat half cooked or uncooked food, especially meat products. Food that does not usually need cooking before eating needs to be thoroughly washed with clean running water. Families with no source of clean running water need to boil their water before domestic use. Keep food at safe temperatures. Food that should be kept cold should be refrigerated and food to be served hot should be served hot.

Use safe water for domestic use at all times and use pasteurised milk products. In situations where pasteurisation is not possible, for own domestic consumption, please boil the milk prior to use.
