Fever in two-month-old babies is caused by various infections, such as rhinovirus, respiratory syncytial virus and other viruses, which can cause fever, cough, nasal congestion and runny nose in children. Infection with bacteria such as Streptococcus pneumoniae and Catarrhella can also cause fever in children. For children with fever, physical cooling can be used to reduce the fever in a timely manner. Because the thermoregulatory center of the two-month-old baby is not well developed, the effect of physical cooling is better, and the child can be given a warm wet towel to wipe the body. If the fever is caused by a bacterial infection, penicillin or cephalosporin antibiotics can be applied.
