The estimates suggest that Omicron cases have, on average, a 15-20 per cent reduced risk of any hospitalisation and an approximately 40-45 per cent reduced risk of a hospitalisation resulting in a stay of one or more nights, they said. (File Photo) Covid-19 infections with the Omicron variant of coronavirus are less likely to result in hospitalisation compared to the Delta strain, according to early results from a study conducted in the UK. The yet-to-be peer-reviewed study suggests that Omicron cases are 15-20 per cent less likely to attend hospital, and 40-45 per cent less likely to be hospitalised for a night or more, compared to Delta. The researchers from the Imperial College London, UK, noted that these estimated reductions in severity must be balanced against the larger risk of infection with Omicron, due to the reduction in the protection provided by both vaccination and natural infection. For example, at a population level, higher num...
