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.
