Proper hand washing vital to guard against diseases

South Canterbury has endured 40 recent cases of campylobacter but health authorities do not believe they are linked.

Statistics for February and March show there has also been 13 cases of pertussis (whooping cough) 14 cases of salmonellosis and two cases of tuberculosis in the region.

South Canterbury medical officer of Health Dr Daniel Williams said campylobacter remained the most common infection.

"Rates are consistent compared to recent months. There is no evidence of any connection between the cases that could indicate a common source of infection.

"The symptoms of campylobacter are very unpleasant and can be very painful, with severe stomach cramps and diarrhoea that can persist for weeks."

Although it can be a food-borne disease, most commonly from undercooked chicken, campylobacter can be caught directly from animals, so people who work with farm stock in dairy and freezing works occupations are more at risk.

Young children who live in the country and are likely to come into contact with faeces from pet animals or chickens are also vulnerable.

Dr Williams said good personal hygiene was vital, particularly thorough hand-washing. "This means using soap, warm water, nail brush and drying on a clean towel."

There were four reported cases of giardiasis and five cases of cryptosporidiosis.

"Both (giardiasis and cryptosporidiosis) are parasitic infections and cause diarrhoea and abdominal discomfort, they are also animal diseases that humans become exposed to when in contact with stock or possibly food or water contaminated with faeces. Again, good personal hygiene is important to reduce risk."

There was also one case of hepatitis A and a single case of shigellosis, infections which are uncommon in South Canterbury and both were acquired overseas.
