Is it effective to enhance immunity when the baby has a fever?

It is common for babies to have a fever. Fever can cause a disorder in the function of the body's temperature center, which will increase the body's heat production while dissipating very little. A normal person's body temperature will also change according to time, season, and environment. The fever is above 37 degrees. There are also many diseases that will have this symptom. So, is it effective to enhance the baby's immunity when he has a fever?

First, is it effective to enhance the baby's immunity when he has a fever? When the body temperature rises during a fever, the activity and reproduction of some pathogenic microorganisms will become less active. The responsiveness of the human immune system is significantly enhanced, including an increase in white blood cell count and enhanced bactericidal activity of phagocytes and neutrophils. Therefore, fever is a beneficial protective mechanism acquired by the human body through evolution to fight against the invasion of pathogenic microorganisms.

Second, fever is the first symptom of the common cold and influenza (commonly known as flu), but there are obvious differences between the common cold and influenza. Zhou Hua said that the common cold is usually caused by viral infection in the early stage, and the main symptoms include local symptoms such as sneezing, runny nose, cough, sore throat, etc., and may be complicated by bacterial infection in the later stage; influenza is caused by influenza virus, and the common cold symptoms may not be very severe, but systemic symptoms such as headache, fever, muscle aches, fatigue, etc. are more severe, and it is more likely to be complicated by bacterial infection.

Is it effective to enhance the baby's immunity when he has a fever? Because the main symptoms of influenza are fever, general fatigue, and poor spirits. Especially for children, their immune systems are imperfect and their resistance is low. Once they get influenza, depending on the subtypes of the influenza virus, the probability of developing severe pneumonia is higher than that of adults, and it can be life-threatening in severe cases. Therefore, early detection and early intervention are necessary. Go to the hospital to check routine blood tests and C-reactive protein (CRP). In the early stages of influenza, the total white blood cell count in a routine blood test is low, only 4,000 to 5,000, and CRP is generally normal. The best effect is achieved when the antiviral drug oseltamivir is used promptly in the early stages of influenza, especially within three days of onset. The latest research has found that the chance of secondary bacterial infection after influenza infection is much higher than the common cold, so antibiotic treatment is also necessary after a doctor's clear diagnosis.
