If the growth rate and doubling time continue, at least 50% of coronavirus (COVID-19) cases to be caused by Omicron variant by mid-December One million by end of December 1% = 10,000 Omicron displays a reduction in protection offered by having had a previous infection or vaccination. There is insufficient data to make any assessment of protection against severe disease, or to assess the severity of illness caused by Omicron. Further studies are underway in the UK and abroad. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1039644/Omicron_SGTF_case_update_FINAL.pdf https://www.gov.uk/government/publications/investigation-of-sars-cov-2-variants-technical-briefings Graph refs https://ourworldindata.org/coronavirus SA.

Though there remain some important uncertainties, Early verbal reports indicate that hospitalisations due to Omicron are now increasing in South Africa. The doubling time for new Omicron infections is currently around 3 days in England It is unlikely to be any slower than a 5-day doubling time (high confidence) Household studies show higher secondary attack rates (high confidence). Why is omicron more transmissible? Combinations of transmissibility and immune escape Some early indications from South Africa suggest less severe disease in those hospitalised A modest reduction in severity would not avert high numbers of hospitalisations if growth rates remained very high. One thousand per day be end of month The peak is highly likely to be higher than 1,000 to 2,000 Omicron hospital admissions per day without intervention For it to be below this level there would need to be only a small degree of immune escape and very high protection from boosters against Omicron With very rapid doubling times a large wave could occur leading to synchronous absences from work.
