II. Symptoms

1. What are the symptoms of COVID-19?

Based on current epidemiological research, the COVID-19 has an incubation period of 1 to 14 days, mostly 3 to 7 days.The main symptoms of COVID-19 are fever, dry cough and fatigue. Some patients may have symptoms such as nasal congestion, runny nose, sore throat, myalgia and diarrhea. Severe patients often have dyspnea and/or hypoxemia one week after the onset of the disease. In severe cases, it can quickly develop into acute respiratory distress syndrome, septic shock, metabolic acidosis, coagulation disorder and multiple organ failure. It should be noted that severe and critical patients may only have moderate to low fever, or even no obvious fever.

Some children and newborns may have "atypical" symptoms, such as vomiting, diarrhea and other digestive system symptoms, or show only weakness and shortness of breath.

Mild infections showed only low fever, slight fatigue, and no pneumonia.

According to the current cases admitted, most of the patients have a good prognosis and a few are in critical condition. Older people, and those with underlying medical problems have poor prognosis.The clinical course of maternal women with COVID-19 are similar to that of the same age group. The symptoms of children are relatively mild.
