Introduction
"Turning from positive to negative" refers to the recovery from a novel coronavirus infection, with test results changing from positive to negative. Persistent cough after turning negative may be due to incomplete recovery, or could result from pharyngeal disorders, allergic cough, recurrence of illness, and other causes. Patients should promptly visit a hospital and, under medical guidance, take appropriate medications for treatment. It is important to avoid crowded places and practice personal protective measures when going outdoors.
Turning from positive to negative refers to the recovery from a SARS-CoV-2 infection, with test results changing from positive to negative. Persistent cough after turning negative may result from incomplete physical recovery, or could be due to pharyngeal disorders, allergic cough, or disease recurrence. Patients should promptly visit a hospital and receive appropriate medication under medical guidance.
1. Incomplete Physical Recovery
SARS-CoV-2 infection is a serious illness that significantly impacts health. Common symptoms include fatigue, fever, and dry cough. Even after turning negative, patients' bodies often cannot recover immediately. Residual symptoms from the acute phase, such as coughing, may persist. It is recommended that patients take medications such as ambroxol hydrochloride oral solution under medical supervision.
2. Pharyngeal Disorders
After recovering from SARS-CoV-2 infection, if the body has not fully regained optimal health, exposure to cold air or other external stimuli may irritate the throat and trigger coughing. In such cases, prompt medical evaluation is essential. Relevant examinations should be completed to identify the exact cause, and treatment for throat-related conditions should be actively pursued under a doctor's guidance.
3. Allergic Cough
After SARS-CoV-2 invades the body, it may damage the respiratory tract, leaving it weakened and hypersensitive. Exposure to allergens in the environment can then trigger allergic cough, which typically worsens at night or in the early morning and often occurs seasonally, especially during spring and autumn. Under medical advice, patients may take medications such as loratadine tablets or cetirizine hydrochloride syrup to relieve discomfort.
4. Disease Recurrence
After apparent recovery from infection, incomplete recovery may lead to recurrent coughing. Patients may follow medical advice to take medications such as Feining Granules or antitussive and expectorant granules for treatment.
In daily life, avoid crowded places and practice personal protection when going out. If respiratory symptoms develop, seek medical attention promptly.
