As at 13 April 2017, the number of cases of typhoid in Auckland remains unchanged. There are 20 confirmed cases, one probable case and no cases under investigation connected with this outbreak.
The data continues to reinforce the view of the Auckland Regional Public Health Service (ARPHS) that the outbreak may have plateaued. All cases are connected to the same church group, and there is no evidence of people from outside this group becoming infected.
The incubation period of typhoid means cases associated with an outbreak often emerge over the course of several weeks as testing continues. APRHS continues to work with the families and church congregation most affected by the outbreak, ensuring all members are receiving appropriate testing, advice and treatment.
Clarification of how typhoid spreads
It is important to understand typhoid is only spread by eating food or drinking water that is contaminated with faeces or urine from a person who has the illness, or who may be a carrier of the bacteria.
Casual social contact, such as hugging and kissing a person, is not a significant risk. People can go about their daily activities as normal, including attending church and other gatherings.
Good hygiene and food safety is always important when sharing and handling food. Wash hands with soapy water for 20 seconds, then dry well with a clean cloth or paper towel every time:
- after going to the toilet
- before preparing food, eating or drinking
- after changing babies’ nappies
Once people are being effectively treated in hospital, the risk of them spreading the disease is significantly minimised. It can take a number of days of monitoring before they are fully cleared by public health. Once cleared, there is no risk of them spreading the disease.
Typhoid has a typical incubation period of 8-14 days but incubation can be up to 80 days. This means cases associated with an outbreak may emerge over the course of several weeks.
