How is three-day-fever contracted?

The cause of the disease is unknown, but it's probably because of a virus that's transferred through the respiratory tract.
The incubation period - from infection to symptoms appearing - is 10 to 15 days. The child is probably infectious during the whole period of the disease and maybe even before the high temperature.

What are the symptoms of three-day-fever?

How is three-day-fever different from other childhood diseases?

It's important that parents of small children know the disease and its characteristic symptoms. It's necessary to distinguish it from other children's diseases, particularly measles.

How does the doctor make the diagnosis?

The typical course of a three-day-fever, followed by a rash, is so characteristic for this children's disease that it's not hard to recognise it from the above symptoms.

How is three-day-fever treated?

The child should be given medication – such as paracetamol (eg Calpol) and ibuprofen (eg Nurofen for children) – to control the fever and to help with any associated aches and pains. Make sure the child drinks plenty of fluids in the three days that the temperature lasts. The rash isn't particularly itchy. Children can go back to childcare when their temperature has returned to normal.

Future prospects

The disease follows the course described above. There are no known complications, and it's a self-limiting condition. Catching it once gives lifelong immunity.

Can children be vaccinated against three-day-fever?

There's no vaccine against this disease.
