Symptoms of infection with NeoCoronavirus vary depending on an individual’s own constitution, whether he or she has been vaccinated against NeoCoronavirus, and the severity of the disease. 1. Mild cases: The main symptoms are typical symptoms such as fever, dry cough, and malaise, while atypical symptoms such as decreased sense of smell and taste, nasal congestion, runny nose, sore throat, conjunctivitis, myalgia, and diarrhea may also be present. 2. Severe patients: mostly seen in the elderly or patients with chronic underlying diseases. In addition to the above symptoms in patients with mild disease, respiratory distress or hypoxemia, as well as metabolic acidosis, coagulation dysfunction, sepsis, shock, multi-organ failure, etc., a very small number of patients may also have ischemic necrosis of limbs, central nervous system involvement and other manifestations. If you have the above symptoms and suspect that you are infected with the new coronavirus, or if you have been in contact with high-risk groups or traveled to high-risk areas, you should go to the hospital in time for nucleic acid testing to make a definitive diagnosis. The epidemic is still in the pandemic stage, do not go out unless necessary, wear masks when going out, do not go to crowded places, actively improve vaccination, pay attention to a healthy lifestyle, enhance physical fitness, and improve immunity.
