What causes a child to have a fever, cough, and runny nose?

The phenomenon of babies having fever, cough and runny nose is a problem that many parents will face in life. We all know that such a situation will indeed have a certain impact and harm on the healthy growth of children. So below we will introduce to you the reasons that are likely to cause children to have fever, cough and runny nose, as well as the most scientific and effective coping methods, so that children can grow up healthily.

Coughing is actually closely related to runny nose. Nasal mucus is the inflammatory substance secreted by the inflamed area of ​​the nose. What flows out from the nostrils becomes snot, and when it is transported to the throat it irritates the throat and causes coughing. If it is spit out from the mouth, it becomes phlegm. If you want to stop a cough quickly, just clean the child's snot. Without the irritant in the child's throat, the cough will stop quickly. It would be best if the child can use the following method to wash the snot directly. If you can't, use a nasal aspirator to suck out your snot at any time to relieve the symptoms of coughing. It is best to take precautions in the future and avoid catching a cold, including people who come into contact with children, because the common cold is also contagious.

The air we breathe every day contains a large number of bacteria, viruses, fungi and other pathogens, and these pathogens continuously enter our nasal cavity through our breathing. But under normal circumstances, the nasal cavity's own detoxification system can transport pathogens to the nasopharynx within 15 to 30 minutes, and eventually enter the stomach for digestion. At this time, the number of viruses remains within the range that the nasal immune system can tolerate, so we will not get sick. However, when inducing factors such as catching a cold, getting caught in the rain, or being overly tired occur, the detoxification function of the nasal cavity is reduced, and the virus can remain in the nasal cavity for a long time.

At this point, the virus can multiply to a number that the nasal immune system cannot withstand, and the virus then invades the human body on a large scale, causing us to catch a cold. (The symptoms are more obvious during menstruation, during pregnancy, and in patients with rhinitis, which means they are more susceptible to colds.) Later, the base number of viruses in the nasal cavity is larger and the number of viruses grows faster, so a large number of viruses begin to spread to other parts of the body, and then the systemic symptoms of a cold begin to appear.
