Among the unvaccinated, Delta variant more than doubles risk of hospitalization

LA Times  

A doctor examines a hospital patient with COVID-19. New research from England’s public health service has confirmed a suspicion spawned by bursting hospital wards across the United States: The Delta variant of the coronavirus not only spreads 50% more readily than the Alpha variant it rapidly overtook, it’s also making unvaccinated people sicker. In addition, unvaccinated people infected with Delta were more likely than those infected with Alpha to seek care in a hospital’s emergency department, the new study found. The findings not only confirm that surges involving the Delta variant will drive more people into hospitals and strain medical resources: By implication, they suggest that when the variant attacks a population with large numbers of unvaccinated people, its victims become more acutely ill. Its results may help explain why the United States is now admitting an average of 12,285 patients to hospitals each day — a rate that has climbed steadily since late July. Among vaccinated people, an infection with the Delta variant was no more likely to lead to hospital admission than a so-called breakthrough infection involving the Alpha variant.
