Introduction
"Post-COVID positive" refers to testing positive for the novel coronavirus. If a patient experiences cough with yellow phlegm after testing positive, it may be caused by factors such as novel coronavirus infection, bacterial lung infection, or acute sinusitis. These conditions typically do not resolve spontaneously. Patients should promptly seek medical care at a hospital and, under a doctor's guidance, receive appropriate medication based on the underlying cause.

1. Novel Coronavirus Infection
Novel coronavirus infection is a highly contagious disease. The virus easily invades the upper respiratory tract, and when it stimulates the bronchial areas, it can trigger irritation leading to symptoms such as coughing and sputum production, with the sputum often appearing yellow. It is recommended that patients take medications such as Compound Liquorice Oral Solution, Powerful Loquat Cough Syrup, or Xingsu Zhike Granules under medical supervision.
2. Bacterial Lung Infection
After entering the body, the novel coronavirus may damage the tracheal mucosa, potentially causing inflammatory reactions and increased respiratory secretions, resulting in cough and phlegm. The sputum is usually white, mucoid, or frothy. However, if pulmonary infection develops and leads to suppurative inflammation in the lungs, the phlegm becomes yellow. In such cases, patients may take antibiotic medications such as Cefixime Capsules, Azithromycin Capsules, or Amoxicillin Capsules as directed by a physician.
3. Acute Sinusitis
Acute sinusitis causes acute inflammation of the sinus mucosa, leading to the production of yellow purulent nasal discharge. When this discharge flows into the pharynx, it irritates the throat mucosa, triggering cough and resulting in yellow sputum. Moreover, novel coronavirus infection, by damaging the tracheal mucosa, may trigger or exacerbate acute sinusitis, worsening the aforementioned symptoms. Patients can use medications such as Oxymetazoline Hydrochloride Nasal Spray or Ephedrine Nasal Drops under a doctor’s guidance for treatment.
