Introduction
After turning from positive to negative, if coughing persists, it is recommended to receive symptomatic treatment under the guidance of a doctor. Meanwhile, drink plenty of water, get adequate rest, and closely monitor any changes in your condition. Persistent coughing after recovery from a COVID-19 infection may not only be due to the aforementioned reasons, but could also result from conditions such as bronchitis. Therefore, as causes vary, treatment methods may differ accordingly, and medication should be taken strictly as prescribed by a physician.

Following a COVID-19 infection, variants such as Omicron primarily affect the upper respiratory tract, where the virus replicates extensively, causing damage to mucosal cells in the airways. Meanwhile, immune cells gather in the area to eliminate the virus. After completing their task, these immune cells naturally die off through metabolic processes, along with the virus-damaged cells, becoming waste materials within the body. The airways cannot accommodate such accumulation, so they must be cleared out. As a result, the respiratory tract secretes mucus, forming phlegm that is expelled through coughing.
After contracting COVID-19, some individuals' coughs disappear within two or three days, while others may take three to five days. In fact, coughing is part of the recovery process—a sign of airway repair. People recovering more slowly need not worry excessively; based on clinical experience, nearly everyone recovers within 14 days. For yellow phlegm, traditional Chinese patent medicines that clear the lungs and resolve phlegm are recommended, such as Compound Fresh Bamboo Extract Liquid, Lingyang Qingfei Pills, Feili Ke, and Jizhi Syrup. Those experiencing sore throat may take Qingyan Drop Pills or Liu Shen Pills.
Persistent coughing after testing negative for the novel coronavirus, aside from the reasons mentioned above, could also be due to bronchitis or other conditions. Therefore, because causes vary, treatment approaches will differ accordingly, and medication should be taken strictly according to medical advice.
