Introduction
In general, turning from positive to negative indicates recovery from a novel coronavirus infection, with test results changing from positive to negative. If the patient continues to cough at this stage, it may be due to the recovery phase or complications caused by the disease. This condition is usually difficult to treat, so patients should promptly go to the hospital and, under a doctor's guidance, take appropriate medications for treatment.
After turning from positive to negative, it means that the patient has recovered from a SARS-CoV-2 infection, with test results changing from positive to negative. If the patient continues to cough at this stage, it may be due to being in the recovery phase or caused by other conditions such as the common cold. Coughing during this period is usually difficult to resolve quickly, so patients should promptly visit a hospital and take appropriate medications under a doctor's guidance.
1. Recovery Phase
SARS-CoV-2 infection is a contagious disease that damages physical health, commonly causing symptoms such as fatigue, fever, and dry cough. Generally, after turning negative, discomfort gradually subsides. However, if small amounts of the virus remain in the body—particularly in the respiratory tract—they may irritate the airways, leading to persistent coughing. It is recommended that patients take medications such as Lianhua Qingwen Capsules or Ambroxol Hydrochloride Oral Solution under medical supervision.
2. Common Cold
SARS-CoV-2 infection can reduce the patient’s immune function, thereby weakening the body’s resistance to diseases. If the patient fails to stay warm and becomes chilled after testing negative, it may lead to frequent coughing. It is recommended that patients take medications such as Sangju Cold Tablets or Dextromethorphan Hydrobromide Tablets under a doctor’s guidance to relieve symptoms.
3. Allergic Cough
Allergic cough may be triggered by allergens such as pollen, indoor dust, dust mites, mold, viruses, or animal dander. If SARS-CoV-2 affects the respiratory tract and triggers this condition, it can cause persistent coughing, often worsening at night or in the early morning, with seasonal patterns typically seen more frequently in spring and autumn. Patients may take medications such as Loratadine Tablets or Cetirizine Hydrochloride Syrup under medical supervision to alleviate discomfort.
