Omicron may cut future severity of Coronavirus, study shows

A strong wave of coronavirus infections driven by the Omicron variant could hasten the end of pandemic disruptions as it appears to cause less severe illness and provides protection against the delta variant, South Africa-based researchers said.

Results among the unvaccinated were unclear, as was whether they had been previously infected.While Omicron is significantly more infectious than delta, hospital and mortality data in countries including South Africa — the first country to experience a wave of omicron infections – appears to show that it causes less severe disease.

The study – an update to one conducted last year – suggests that Omicron can displace Delta, the researchers led by Alex Sigal of the Africa Health Research Institute said.“The implications of such displacement would depend on whether Omicron is indeed less pathogenic than Delta,” the researchers said. “If so, then the incidence of Covid-19 severe disease would be reduced and the infection may shift to become less disruptive to individuals and society.”

A laboratory study that used samples from 23 people infected with the Omicron variant in November and December found that while those who previously caught the Delta variant could contract Omicron, those who get the Omicron strain couldn’t be infected with Delta, particularly if they have been vaccinated, the researchers said.Australian Prime Minister Scott Morrison.18 January 2022 - 08:30 File photo: GALLO IMAGES/ER LOMBARD A  new study  has shown that the Omicron wave in the Western Cape was much less deadly than previous waves, owing to vaccination, high rates of past infection in the community, and reduced risk of severe disease and death owing to the variant itself.18 January 2022 - 08:30 File photo: GALLO IMAGES/ER LOMBARD A  new study  has shown that the Omicron wave in the Western Cape was much less deadly than previous waves, owing to vaccination, high rates of past infection in the community, and reduced risk of severe disease and death owing to the variant itself.

While Omicron is significantly more infectious than delta, hospital and mortality data in countries including South Africa — the first country to experience a wave of omicron infections – appears to show that it causes less severe disease. Australian voters are losing confidence in Morrison and his Liberal-National Party coalition government on the economy, jobs, health and the response to a fast-moving Omicron wave, according to a poll done by research company Resolve Strategic for the Sydney Morning Herald newspaper. The study – an update to one conducted last year – suggests that Omicron can displace Delta, the researchers led by Alex Sigal of the Africa Health Research Institute said. The study was led by Prof Mary-Ann Davies, director of the Centre for Infectious Disease Epidemiology & Research at the University of Cape Town, working in collaboration with 46 others from the Western Cape department of health; the national department of health; the National Health Laboratory Service; the Universities of Cape Town, Stellenbosch, the Witwatersrand, and KwaZulu-Natal; the Francis Crick Institute; and Imperial College London. “The implications of such displacement would depend on whether Omicron is indeed less pathogenic than Delta,” the researchers said. 11 to 15, before an Australian court upheld a government decision to cancel unvaccinated tennis star Novak Djokovic's visa just ahead of the Australian Open. “If so, then the incidence of Covid-19 severe disease would be reduced and the infection may shift to become less disruptive to individuals and society. According to the authors, this is “the first study from a setting of high prior seroprevalence to demonstrate less severe disease in wave four”, adjusted for vaccination and prior diagnosed infection.

” We have an update to our study which found enhancement of Delta immunity with . 1 to enter the country without being vaccinated against Covid-19 sparked fury in Australia, and became a political issue for Morrison. The study sought to answer if past infection or vaccination still protected people exposed to Omicron, and the extent to which this protection was causing milder cases – or if Omicron is inherently less dangerous.
