When children suffer from runny nose and cough, there is a certain tendency for them to heal themselves. The reason why children have runny nose and cough is that most of the symptoms are caused by respiratory infections. In children with respiratory infections caused by viral infections, the symptoms of runny nose and cough are not particularly intense. In particular, children who do not have a high fever and are not in a particularly poor mental state, and whose appetite for food is not affected, have a tendency to heal on their own. In this case, parents only need to give the child appropriate more warm water, and pay attention to the appropriate clothing thick wear can be, most of the children’s disease will slowly heal in about a week, this is the general situation. If a child has a high fever that does not subside and a particularly high white blood cell level, the likelihood of self-healing is poor and medication should be administered promptly.
