If a child's cold is considered to be caused by a viral infection, it is important to monitor the baby's temperature and mental response, among other factors. If the child does not have a fever, or only has a low fever and is in good spirits, simply monitoring the baby’s condition and ensuring they drink plenty of warm water and eat light, easily digestible foods is sufficient, with no other special requirements needed. However, some colds, such as those with persistent high fever, lethargy, and poor responsiveness, are more serious and require immediate attention. It is crucial to visit the hospital for further diagnosis and treatment in these cases. Sometimes, the impact of a cold should not be underestimated, as diseases like myocarditis and intracranial infections can initially be triggered by a cold. Therefore, a comprehensive analysis is necessary to make a judgement, and treatment should proceed under the guidance of a doctor.
