Symptoms of being infected with a new crown include asymptomatic infections, mild cases and severe cases, with asymptomatic infections having no obvious symptoms. Mild cases may present with symptoms such as low-grade fever and mild malaise, while severe cases may present with symptoms such as respiratory distress.
Mild cases may simply present with low-grade fever, mild malaise, and disturbances in the sense of smell and taste, with no signs of pneumonia. Some patients have no symptoms and are considered asymptomatic infected persons.
Severe patients may develop respiratory distress or hypoxemia one week after the onset of the disease, and severe cases may rapidly progress to respiratory failure, or even shock, coagulation disorders, and multiple organ failure.
In daily life, we should maintain good personal hygiene habits, try to avoid close contact with people with respiratory symptoms, avoid crowded or confined places, and wear disposable masks when going out.
