If you think your child has typhoid fever, see a doctor urgently.
Typhoid fever (typhoid) is a disease caused by the bacteria Salmonella typhi. Most people with typhoid fever in New Zealand have caught the disease while travelling overseas, especially countries in the Pacific.
Paratyphoid fever is a similar illness to typhoid fever. It is caused by Salmonella paratyphi.
Typhoid fever is rare in New Zealand, with about 40 known cases a year. Children are more at risk of getting typhoid fever.
Typhoid bacteria is found in the poo of infected people. People catch typhoid fever if they come in to contact with this poo.
Your child can get typhoid fever from drinking water or eating food that has been contaminated by the typhoid bacteria.
This can happen if food or drink is handled by someone with typhoid fever or who is a carrier of the bacteria.
Eating shellfish from beds that are contaminated with raw sewerage can cause typhoid fever.
Typhoid fever easily passes from one person to another if people don't wash their hands properly.
You can get the bacteria from changing nappies of a baby with typhoid fever.
Some people who have typhoid fever do not get sick but they can still carry the bacteria and make others sick.
Once your child is infected, it usually takes 1 to 3 weeks for symptoms to develop. It can take from 3 days to over 60 days to develop symptoms.
The illness starts slowly with fevers, chills (feeling cold and shivery). Your child could have a temperature of up to 39 to 40 degrees Celsius.
Other symptoms include:
If you think your child has typhoid fever, see your family doctor urgently.
Typhoid fever is often severe and children can die from the disease. Most children and adults have to spend time in hospital.
Tell your doctor if you have been overseas recently. If your doctor suspects typhoid fever, they will also ask your child to do a blood test and provide a poo sample. They may refer your child to the hospital.
Don't stop antibiotics when your child starts to feel well as they might get sick again.
The treatment for typhoid fever is antibiotics. Make sure your child takes all of their antibiotics. Don't stop when they start to feel well as they might get sick again.
If your child's symptoms are milder, they can recover at home and they should feel better in a few days. If your child's symptoms get worse, see your doctor urgently.
If your child has severe symptoms, such as vomiting that doesn't stop, severe diarrhoea or a swollen tummy, your child needs to go to hospital.
If you don't seek help urgently and get treatment, your child could have serious complications or even die.
Complications include:
See information about typhoid fever in Samoan at the Auckland Regional Public Health Service website [1]. The information is about typhoid fever in both adults and children.
Your health professional will contact the public health unit if your child has typhoid fever. The public health unit will give you instructions about isolating and when your child can go back to daycare or school.
Some children get sick again about a week after they finish their antibiotics. If your child starts to feel sick again, see your doctor as soon as possible.
Yes, if you are travelling to one of the countries where the rates of typhoid are high, talk to your doctor about immunisation for your child before you go. Typhoid immunisation is only for children over 12 months and there will be a cost for this. Talk to your family doctor, or a travel medicine doctor for more information.
Visit the Safe Travel website before you travel [2] - it provides information about the latest outbreaks.
