- A sudden rise in temperature can cause febrile fits
- Rash, usually small reddish spots and lasting 12-14 hours (once temperature has dropped)
Treatment for three-day fever
There are no known complications of three-day fever and the condition usually eases after the three day period. Ensure your child drinks plenty of fluids during outbreak of a high temperature. The rash is very rarely itchy and won’t require any medications.
