Omicron has a higher rate of asymptomatic carriage, according to latest research
“Omicron may have a much higher rate of asymptomatic ‘carriage’ than earlier variants of Covid-19,” says Dr Lawrence Corey, from the SA Medical Research Council (SAMRC) and lead author of a preliminary study on the subject. “Since so many people may be asymptomatic, we cannot always know who is carrying the virus, but we do know what we can do to protect ourselves and to help prevent further spread: wear a mask; wash hands; avoid large, indoor gatherings; and get fully vaccinated as soon as possible,” Corey told Business Live (11 January 2022)
“SAMRC president Professor Glenda Gray said the findings are preliminary - part of a paper posted on the medrxiv.org website before peer review and publication - but they appear to be in line with the bigger picture coming together about Omicron’s high transmissibility.”
Prof LindaGail Bekker, director of the Desmond Tutu HIV Centre at the University of Cape Town, said the data also strongly supports the need to reach global equity with primary vaccination and to develop second-generation vaccines that may be even more protective against acquisition.
