BackgroundTo assess the comprehensive dynamics of outcomes during the SARS-CoV2 B.1.617.2 (Delta variant) compared to the Alpha variant outbreak in the United Kingdom.MethodsIn this observational study of the cases reported by Public Health England for confirmed (sequencing and genotyping), SARS-CoV2 cases Delta variant (n=592,692) and Alpha variant (n=150,934) were used. Outcomes were analyzed by age groups and compared with all reported weekly cases in the UK.ResultsThe Delta variant surge is associated with a significantly lower case fatality rate (0.43% vs 1.07; RR 0.39; 95% CI 0.37-0.42; PConclusionsThe Delta variant surge is associated with significantly lower mortality and hospitalizations than the Alpha variant. As the Delta variant surge progressed, ≥50 years old had a significant increased percentage of cases, hospitalizations and a significant increased COVID-19 deaths occurred among ≥70 years old age group. |
