What are the symptoms of a second positive result?

Generally, a second positive result (secondary positive) refers to a recurrence of a positive reaction after infection with the novel coronavirus. Symptoms include fever, cough, fatigue and tiredness, difficulty breathing, diarrhea, or vomiting. If necessary, timely medical attention is recommended. The specific analysis is as follows:

1. Fever: After the novel coronavirus invades the body, the immune system activates its defense mechanisms, releasing pyrogenic factors that cause an increase in body temperature, possibly reaching above 37.5°C, or even higher.

2. Cough: If the virus infects the respiratory tract, it may irritate the respiratory mucosa, triggering a cough reflex to expel viruses and secretions from the respiratory tract, often accompanied by symptoms such as sore throat and dryness in the throat.

3. Fatigue and Tiredness: The novel coronavirus may affect the body's metabolic functions and nervous system, causing a sense of fatigue, leading to physical tiredness, weakness, and a significant decrease in exercise tolerance.

4. Difficulty Breathing: Due to damage to lung tissue and worsening inflammation, shortness of breath may reoccur in cases of secondary positivity, possibly accompanied by chest tightness and breathlessness.

5. Diarrhea or Vomiting: This may be caused by the virus affecting the digestive system. Some patients infected with the coronavirus may experience gastrointestinal symptoms such as diarrhea and vomiting. In severe cases, it may lead to problems such as loss of appetite.

Patients can use antiviral oral liquids, Lianhua Qingwen capsules, Ganmaoling granules, and other medications for treatment under a doctor's guidance. At the same time, it is important to maintain good indoor air circulation, practice personal hygiene, and avoid excessive fatigue in daily life.
