Child fever/rash: home-care and safety net

If your baby is 90 days old or younger and has a rectal temperature of 38.0 C or higher, seek urgent medical assessment even if they seem well. A fever measured at home still counts. Contact a clinician for fever in any baby younger than 6 months.

Offer frequent fluids, monitor urine output, and use fever medicine only at the dose recommended by your clinic.

Get urgent care now for trouble breathing, child difficult to wake, stiff neck, seizure, purple/non-blanching rash, repeated vomiting, no urine for many hours, or signs of dehydration.

Contact your clinic if fever lasts more than 48-72 hours, sooner if your child is worsening or you are worried. If measles is suspected, call before arriving so the clinic can protect other patients.
