+Outcome measures

Primary outcomes

Coinfection [from admission to 7 days after admission]: The investigators defined coinfection as coinfected bacteria, fungi, or other viruses with SARS-CoV-2 that occurred from admission to 7 days after admission. If a diagnosis was at the time of or within the first 48 hours of COVID-19 hospital admission, these infections were defined as community-acquired infections. If diagnosis occurred ≥48 hours to 7 days after admission for COVID-19, these infections were defined as early-onset hospital-acquired infections.
