The latest findings out of Singapore, published this week in the peer-reviewed medical journal Clinical Infectious Diseases, involve a comparison between 829 hospitalized patients infected with one of three variants of concern — including delta — and 846 patients admitted to hospitals with the original coronavirus strain in early 2020.
"After adjusting for age and sex, [delta] was associated with higher odds of oxygen requirement, ICU admission, or death," the research team wrote.
The findings of the study are similar to what was seen in both a broad analysis of Singapore's national-level data and a detailed study of patients with severe outcomes, the paper continued.
The conclusions also echo other international studies, including one out of Scotland and another from a team in Ontario, which both found a heightened risk of severe outcomes following infection with the delta variant.
