Objective To explore the clinical management and epidemiological measures to a second-generation patient with coronavirus disease 2019 (COVID-19) and her close contacts, so as to identify the asymptomatic cases earlier and stop the spreading of COVID-19.
Methods On February 5, 2020, a 49-year-old female patient was admitted to People's Hospital of Leshan, and she's the second-generation sufferer of COVID-19 and infected by her son-in-law. She was tested positive after 15 days' quarantine.
Results The patient remained asymptomatic during the whole medical observation, but the 2019-nCoV nucleic acid test of pharyngeal swab was positive before she was discharged. And her clinical symptoms gradually appeared.
