Persistent cough and fever are manifestations of respiratory tract infections. At this time, it is necessary to actively treat the respiratory tract infections, find the pathogen to target and kill the pathogen, for example, if it is a virus, you need anti-viral, if it is a bacteria, you need antibiotics, not just to stop the cough or reduce the fever. This is because coughing is a function of expelling phlegm and garbage outward when there is an infection in the lungs. Fever mobilizes the body’s immune system. As the body is infected by pathogens, there are toxins that stimulate the body to cause fever, which is what mobilizes the body’s immune system to expel the cause of fever, and must be treated actively. If the cough and fever continue to worsen, it also means that the inflammation in the lungs is further aggravated, which means that the treatment is not enough at that time and needs to be strengthened or changed to find a more suitable method. In short, it is inappropriate to deal with this condition on your own, and hospitalization is usually required.
