If the baby is in good spirits during the fever, it proves that the illness is mild and that the baby is in good health, but it is also important to treat it promptly, otherwise it is likely to worsen. Fever-reducing medications, such as acetaminophen syrup, can be used to relieve mild fever symptoms. In case of recurrent fever, oral anti-inflammatory drugs such as cephalexin, for example, cefaclor pellets, can also be taken and are very helpful in relieving fever. Anti-viral medications, such as ribavirin, can also be used. For babies with mild disease, the fever can be completely controlled through systematic treatment in about 3 days. During the treatment period, pay attention to a light diet, do not eat too much food, and pay attention to drinking more plain water, which is conducive to rapid improvement of the disease.
