Background: PCR screening for COVID-19 has a significant false-negative rate and requires several hours to complete. A fever clinic was set up at Shekou Hospital, Shenzhen, China to rapidly identify high-risk patients.

Methods: A total of 5,710 patients were screened on the basis of (1) epidemiological history and symptoms, (2) pneumonia on chest CT scan, (3) white blood cell count, and (4) evaluation by a senior physician. Confirmative diagnosis was based on two positive PCR tests.

Results: A total of 247 patients were quarantined pending confirmative diagnosis. Nine had confirmed COVID-19. Of those, all had COVID-19–related symptoms, and eight had positive epidemiological history. Chest CT scans for pneumonia were positive in seven confirmed cases and indeterminate in two confirmed cases. The sensitivity, specificity, positive predictive value, and negative predictive value of the rapid screening were 100%, 93.39%, 3.64%, and 100%, respectively.

Conclusion: Rapid screening helped to quickly identify and isolate patients with COVID-19.
