Abstract:A 7-day-old male neonate was admitted due to testing positive for SARS-CoV-2. The neonate was born through cesarian section at 40 weeks and 2 days of gestation. His mother was diagnosed with coronavirus disease 2019 (COVID-19) caused by Omicron variant infection 1 day before delivery. The neonate was separated from his mother after birth and was taken care of by his father. Three days after the neonate was born, his father was also diagnosed with COVID-19. The neonate was diagnosed with COVID-19 on day 7 of life. The neonate presented with hyperpyrexia, dyspnea, hypoxia, and feeding difficulties, and the chest CT showed the coexistence of consolidation and ground glass-like changes mainly located below the posterior pleura. He was given symptomatic support treatment such as low flow oxygen therapy and posture management after admission. He was cured and discharged after 10 days of hospitalization. This is the first reported case of neonatal severe COVID-19 caused by Omicron variant infection in China. It is necessary to take appropriate protective measures for the neonate to prevent infection when the mother or caregiver of the neonate is a suspected or confirmed cases of COVID-19.
