Temperature has to be around 100.4F for fever. Monitor temperature regularly. Could be viral orenvironmental factors. If temperature is above 100F you can give paracetamol , do tepid sponging. Look for cough cold,Vomiting. Maintain hydration.

Greetings temperature between 99°F and 99.8°F is generally considered a normal daily fluctuation or a very mild elevation rather than a true medical fever. In children, a true clinical fever is typically defined as a thermometer reading of 100.4°F (38°C) or higher, which is why they may have no other symptoms. Minor temperature shifts can occur naturally due to physical activity, warm clothing, excitement, or simply a warmer room environment. Sometimes, a slight elevation can also be the early incubation phase of a minor viral infection before standard cold or cough symptoms appear. Keep your child well-hydrated with plenty of fluids, dressed in lightweight clothing, and continue to monitor their temperature over the next few days. Please consult a pediatrician if their temperature rises above 100.4°F, if the elevation persists beyond 5 days, or if they become unusually lethargic.
