What are the symptoms of COVID-19?

COVID-19 refers to novel coronavirus. Symptoms of novel coronavirus infection include fever, dry cough, fatigue, decreased sense of smell and taste, poor breathing, diarrhea, conjunctivitis, headache, dizziness and chest pain. 1, Fever: Fever symptoms are the most important symptoms of COVID-19 infection, because COVID-19 causes lung inflammation in the body and stimulates the body temperature center, which leads to fever symptoms. 2, dry cough: lung tissue was infected by novel coronavirus, resulting in inflammation, irritation and cough. 3, fatigue: mainly due to the performance of systemic fatigue caused by inflammatory reaction. 4, sense of smell and taste decline: some patients' sense of taste and smell will be disordered, leading to functional decline. 5, poor breathing: inflammation in the lungs, alveolar function decline, more likely to lead to patients with dyspnea, chest tightness and shortness of breath and other symptoms. 6. Diarrhea: novel coronavirus produces too many toxins in the body, which makes the gastrointestinal function worse and makes it easier to have diarrhea. 7. Conjunctivitis: Conjunctiva comes into contact with novel coronavirus, so it is infected. This symptom is often manifested as itchy eyes, tears and dryness. 8. Headache: Fever symptoms will cause vasodilation of the cerebral vessels, which will stimulate the peripheral nerves and lead to headaches. 9. Dizziness: Symptoms such as fever, dyspnea, chest tightness and shortness of breath make the patient's brain lack oxygen for a short time, leading to dizziness. 10, chest pain: Severe and persistent cough symptoms can induce chest pain, which may lead to chest lesions.
