About 10% to 20% of Covid sufferers have reported to have long Covid. This is when the patients take longer than 12 weeks to get full recovery. In one July report from the U.K.’s Office for National Statistics, more than 4% of vaccinated and boosted adults in the U.K. who were infected by Delta, Omicron BA.1, or BA.2 still had symptoms at least 12 weeks later.
