Spring infection warning

The number of tummy bugs has been low during the winter, but health authorities warn of an increase in the spring, and to be vigilant over measles.

South Canterbury medical officer of health Daniel Williams said the number of gastrointestinal infections was generally lower during the winter months but rose during spring as contact between people and young animals increased.

"Campylobacter, salmonella, cryptosporidium, giardia and yersinia live in the gut of animals and birds, and may be present in large numbers in their faeces.

"People can swallow the organisms by eating contaminated food, drinking contaminated water or milk, or by transferring bugs from their hands to their mouth. Bugs may also be passed from person to person in household or other settings. People who work with animals are at particular risk of developing gastrointestinal infections," Dr Williams said.

During August Timaru had four cases of campylobacter, and one case each of yersinosis, cryptosporidium, giardia and one case of whooping cough.

"Although there have not yet been confirmed cases of measles in South Canterbury, the number of cases around the country continues to increase, with the majority of cases in Canterbury.

"Measles is a highly infectious and potentially serious disease. Over 10 per cent of Canterbury cases in the current outbreak have been hospitalised."

Measles is preventable by immunisation with MMR vaccine. Two vaccinations are required for full protection.
