Abstract: The patient had several close contacts with friends from Wuhan, the epicenter of the epidemic. His mother and father had close contact with him. His father was later diagnosed with COVID-19 infection after a positive reverse transcription PCR test for SARS-CoV-2 RNA. The patient and his mother were diagnosed as suspected cases of COVID-19 based on a history of exposure, clinical manifestation, and imaging examination. However, the patient was tested more than three times with the reverse transcription PCR test for SARS-CoV-2 RNA, and the results were negative each time. COVID-19 should be suspected, regardless of SARS-CoV-2 test negativity, for recent close contact with a confirmed case and respiratory symptoms.
