The chances of becoming infected with COVID-19 while hospitalized increased as the pandemic progressed, according to recent Canadian research.
In fact, significantly more Canadians became infected with hospital-acquired COVID-19 during the fifth and sixth waves of the pandemic — the first two Omicron waves from late 2021 until the spring of 2022 — than during earlier waves, according to the study published in the journal JAMA Network Open. Researchers looked at cases of patients hospitalized with COVID-19 between March 2020 and May 2022.
