November 28, 2021 "It is not yet clear whether the Omicron variant of Covid-19 is more transmissible (for example, more easily transmitted from person to person) than other variants, including Delta": this is what the WHO reports, in a new update on the pandemic situation.
"It is still unclear whether Omicron infection causes more serious disease than infections with other variants, including Delta."
"Preliminary data suggests that there are increasing hospitalization rates in South Africa, but this could be due to the increase in the overall number of people infected, rather than a specific infection with Omicron."
And "there is currently no information to suggest that symptoms associated with Omicron are different from those of other variants. The infections initially reported were among college students, younger individuals who tend to have milder disease, but understanding of the severity level of the Omicron variant will take "more time" from days to several weeks ".
