Coughing symptoms in babies after a fever are most often caused by respiratory infections. In the early stages of respiratory infections, the lesions are limited to the upper respiratory tract and may be feverish, with discomfort in the throat and sore throat. With the development of the disease and the medication, the body’s defense mechanism is enhanced, and although the body temperature is controlled, the infection still persists in the body and is not completely cleared, or even continues to spread to the lower respiratory tract, or is repeatedly cold and infected, leading to coughing and irritation of the respiratory tract causing coughing. Coughing is a defensive neural reflex of the body that facilitates the removal of secretions and harmful factors. Cough symptoms are mild after fever in upper respiratory tract infections, and the cough gradually decreases and slowly heals in 3-5 days. If the cough persists, note whether there is a combination of bacterial infection as well as bronchitis. If the cough continues to worsen, coughing up sputum is obvious, or even wheezing, and the child becomes mentally ill, be alert to the presence of bronchitis or pneumonia. If your baby has a cough after a fever, it is important to seek medical attention and take medication in a timely manner. Care should pay attention to respiratory protection, do not get cold repeatedly, pay attention to rest, drink more water, and keep your child’s bowels open.
