A fever for one day is often due to a viral infection and may not need antibiotics. Paracetamol can help control fever, and improvement is a good sign. Antibiotics are only needed for bacterial infections and should not be given routinely. Consult a doctor if fever persists, worsens, or new symptoms appear.

A mild fever of 99.1F with a cold in a 7-month-old is usually viral. Antibiotics are not needed unless a doctor finds a bacterial infection. Consult a paediatrician if the fever rises or persists beyond 2-3 days
