There is an outbreak of typhoid in Auckland and 10 people are in hospital as a result.
The Auckland Regional Public Health Service is tracing people who have been in contact with the confirmed cases and is following protocols to control the spread of the disease.
It can be a serious illness and is potentially fatal but can be treated with antibiotics.
Medical Officer of Health Dr David Sinclair says typhoid is spread primarily through water and food but can be spread person to person.
Dr Sinclair says good basic hand-washing is one of the best ways people can protect themselves.
Symptoms include a high fever developing over several days, headaches, general weakness and muscle aches. Stomach pain and constipation are also common but some people get diarrhoea.
ARPHS has alerted the health sector to the outbreak.
Dr Sinclair urges anyone with those symptoms and is feeling very unwell to see their doctor or an after-hours clinic. NZME
