Diagnosis
The main clinical manifestations are fever, fatigue, myalgia, dry cough, and shortness of breath. The diagnosis of COVID‐19 is based on comprehensive contact and travel history and precise laboratory tests. Currently the primary epidemiologic risk factors for COVID-19 include travel from mainland China (especially Hubei Province) or close contact with infected individuals within 14 days of symptom onset. Current diagnostic tools were the nucleic acid or virus gene tests. In a recent report, sensitivity of chest CT in diagnosing COVID-19 was shown to be greater than that of RT-PCR (98% vs 71%)7. As the risk of radiation to the fetus is very small, chest CT scan is considered to be the most useful test to confirm or exclude pregnant women with viral pneumonia.
