Under normal circumstances, children with viral colds and fevers take about 7 days. Generally, the symptoms of fever will be more obvious in 1-3 days of the child’s viral cold, and the child will have repeated high fever, and the body temperature will usually reach about 39℃. During the period of viral cold and fever, the child must pay attention to drink more water to replenish the body’s moisture, and drink more water can also help relieve the symptoms of high fever. Parents should also take the child’s temperature regularly. If the child has a high fever, acetaminophen should be given to reduce the fever, which can be repeated after 4-6 hours, but the fever-reducing medication should not be given more than 4 times in 24 hours.
