Numbers of COVID cases likely to be the #OmicronVariant are increasing rapidly in England
SGTF data indicate 994 likely cases, including 2% of swabs from 4th December
This gives a worst case scenario of ~2500 cases so far and an R-value of 3.47 (CI 2.75 - 4.40)
Detail in thread Image This is based on “Spike Gene Target Failure” (SGTF) in the qPCR assay used on approximately 40% of samples. Data provided by UKHSA, but analyses not endorsed by them.
Since 20th November, we have this information for 256k cases. 994 of these (0.4%) are likely to be Omicron.
