People who are vaccinated and received a booster vaccine against Covid-19 recover from symptoms of the Omicron variant earlier than those who have been infected with the Delta variant of coronavirus. Specific, more than three days According to a study published in The Lancet.
Research has also seen that Omicron infected people are significantly less likely to lose sense of smell and confirmed earlier research that it is less serious.
To discover the differences in how Omicron and Delta make patients sick, researchers at King’s College London used a free smartphone app called ZOE in which more than 63,000 vaccinated people in Britain between the ages of 16 and 99 reported their Covid symptoms between June 2021 and January 2022.
For those with two doses of vaccine plus a booster, symptoms for Omicron lasted 4.4 days, compared to 7.7 for Delta, a difference of 3.3 days.
Also, in people who received only two doses but not the third booster, symptoms with Omicron lasted up to 8.3 days, compared to 9.6 days with Delta.
This faster recovery suggests “that the period of infectiousness could be shorter, which in turn would affect public health policies,” the researchers said.
The study, which is presented in the European Congress of Clinical Microbiology and Infectious Diseasesalso found that only 17% of people with Omicron lost their sense of smell, compared to 53% with Delta.
However, people on Omicron had a 55% increased risk of having a sore throat.
The author of the study, Cristina Menni points out that it was the first peer-reviewed article with a large number of participants who analyzed the different symptoms of the two variants.
