SARS-CoV-2 seroconversion in children with acute psychiatric symptoms versus controls

Since the beginning of the pandemic, studies reported an increase of children’s mental health issues, and question the impact of SARS-CoV-2 on psychiatric symptoms. We questioned if children with acute psychiatric symptoms (n=52), hospitalized from December 2020 to April 2021 (second lockdown period in France) would have been more infected by the SARS-CoV-2 and thus more seroconverted than general population sex-, age- matched controls admitted to the emergency department for non-psychiatric and no history of apparent infection (n=52).
