Background SARS-CoV-2 was first identified in December 2019 in samples obtained from a 61 years old man who died of acute respiratory failure in the city of Wuhan, China with a subsequent outbreak in China. Till now, there were rare reports about childhood patients with SARS-CoV-2 infection.
Methods We report 37 children diagnosed with SARS-CoV-2 infection admitted in the Third People’s hospital of Shenzhen from December 11, 2019 to February 11, 2020.
Results There were 9 mild cases, 20 ordinary cases and 1 severe case and 7 cases with asymptomatic infection. The age ranged from 7 months to 17 years old and the median age was 7 years old. The median length of hospital stay is about 14 days. The time from illness onset to diagnosis ranged from 0.5 to 10 days (median time: 2 days). The common clinical features were fever (29.7%, 11/37) and cough (32.4%, 12/37). No death occurred among our patients. 86.5% (32/37) children were infected with SARS-CoV-2 after their family members (parents or grandparents). 1 child was identified with SARS-CoV-2 infection after 3 times testing. The majority (78.4%) of cases occurred in those children who travelled to Hubei Province.
Conclusions The majority of childhood cases with SARS-CoV-2 infection was mild or ordinary COVID-19 and had travelled to Hubei Province. Family cluster transmission of SARS-CoV-2 was suspected in 86.5% of patients. Timely continuous SARS-CoV-2 pathogen testing is recommended. Key words: SARS-CoV-2; infection; children
