The Omicron variant of Covid-19 may have fewer long-term effects, Long Covid, than Delta did previously. This is what emerges from a study by King’s College London, published in ‘The Lancet’, with data monitored by the ‘Zoe Health Study’ platform. The research has been peer-reviewed and is the first on the differences in Long Covid between different variants.
The work analyzed 56,003 cases of adults in the UK who first tested Covid-positive between December 20, 2021 and March 9, 2022, when Omicron was the dominant strain. The researchers then compared these data to 41,361 positives between June 1, 2021 and November 27, 2021, with Delta prevailing. Well, the analysis showed that 4.4% of Omicron cases had also had a Long Covid, while with Delta it was 10.8%. However, the absolute number of positive people who had consequences from the infection was higher when Omicron was the dominant variant.
According to Claire Staves, lead author of the study, “the Omicron variant appears to be substantially less likely to cause Long Covid than previous variants, but we still have one in 23 people who contract the disease and continue to have symptoms for more than 4 weeks. . It is therefore important to continue to support these people at home, at work and within public health. ”
