Bronchitis with recurrent fever for 6 days may be due to a more intense inflammation. It is recommended to first go to the hospital for a routine blood test, and in addition to take a chest X-ray. If the blood picture is more significantly elevated, then there must be a bacterial infection, and the degree of thickened and disordered lung texture on the chest X-ray is also directly related to the inflammation in the lungs. If the inflammation is heavy, then antibiotic drugs should be used promptly, and only by bringing the inflammation under control can the fever be changed. As well as the application of cough expectorant and wheezing drugs, during the treatment period more rest, drink more water, and avoid excessive exertion with a light diet. After recovery, strengthen physical exercise, enhance physical fitness and try to prevent colds. Improve the living environment and avoid contact with substances that may cause allergies.
