Many children have a low-grade to moderate fever, but some can run higher temperatures, especially in the first couple of days. Parents often search for how long fever lasts with hand, foot, and mouth because the timing can vary, but fever commonly improves within 1 to 3 days. The bigger concern is not just the number on the thermometer, but whether your child is drinking, staying alert, and breathing comfortably.
