Every year in the autumn and winter, the flu starts to rage, some children repeatedly cough phlegm fever and runny nose, parents are at a loss, thinking that the baby’s resistance is low, fear of pneumonia, and keep running to the hospital, in the end, is this helpful? In fact, in the season of flu outbreak, in general, after children are infected once, they already have a certain degree of immunity, but because the flu virus mutates quickly, so, if you are not careful, there will be re-infection, and the chance of cross-infection in the family is also very high. Moreover, hospitals are mixed with various viruses and bacteria, each occupying its own base, and although medical disinfection is more diligent than at home, it still does not prevent patients from checking each other’s cross-infection pathways. According to the child’s condition, generally the flu symptoms are heavy, but the signs are light, so if the fever is effective with oral antipyretic drugs and the fever does not exceed 3 times a day, there is no need to rush to check the peripheral blood, but if there is a high fever that does not subside or too many times a day, it is necessary to consult a doctor immediately. Complete blood tests, such as routine blood tests, to clarify the pathogen and treat the cause. Next is the case of coughing and phlegm. If the cough is obvious in the morning and at bedtime, or if the cough is occasional during the day with a short interval, there is no need to be nervous, you can take a little oral cold medicine containing paracetamol and other ingredients to help you sleep, and there is no need to intervene excessively for coughing and phlegm that does not affect sleep. It is normal for babies with influenza to have a reduced appetite, so don’t worry about being hungry. It is normal for the intestinal tract to be weakened at this time, so drink more water to replenish body fluids and stimulate humoral and cellular immunity, which is very helpful to shorten the course of the disease. There are also symptoms such as nasal obstruction, runny nose, runny eyes, etc. The treatment of these symptoms also needs to be analyzed on a case-by-case basis, generally speaking, khat symptoms may last for a while, but not too long. If the runny nose does affect sleep at night, oral antihistamines can be taken immediately. Finally, if your child has a cough with wheezing, or hoarseness, and a cough that shortness of breath after sleeping at night, you should consider seeking immediate medical attention to avoid acute laryngitis, wheezing bronchitis, pneumonia, and other more dangerous respiratory infections that can affect your baby’s development. All in all, the flu is not under your control, but we can respect and stay away from it. Opening windows and ventilation is the only way to reduce the concentration of virus at home, washing hands diligently can block the means of transmission, wearing a mask after falling ill is a means of mutual protection and care, drinking more water to replenish body fluids can regulate the mobilization of the body’s own immune function, which is more effective than any drugs. Last but not least, sufficient sleep can keep adults and small people away from the nightmare of influenza. Well, I wish you all good dreams every day and don’t let the cell phone tablet occupy our sight before going to bed.
