Micron is confirmed in 106 countries
According to the WHO report, the Celtic variant of the coronavirus is dominant among global virus samples, but the omicron variant is on the rise and poses a risk.
In a section of the report on the prevalence of worrisome variables, the organization said 96% of globally sequenced samples were delta, up from 99.2% the previous week, and 1.6% were omicron, compared to 0.4% from the previous week.
According to WHO data, the omicron variant has been confirmed in 106 countries.
“Recent evidence indicates that the omicron variant has a growth advantage over the delta variant and is spreading rapidly, even in countries with documented community transmission and high levels of population immunity,” the organization said.
Data on the risk is limited, but hospitalizations are increasing in the UK and South Africa.
“Given the rapid increase in the number of cases, health systems may be overwhelmed. Preliminary data indicate that there is a decrease in omicron neutralization in those who have received a series of primary vaccination or in those who have been previously infected with SARS-CoV-2, which may indicate A level of humoral immune evasion”.
Because of these factors, “the overall risk related to the omicron variant of concern remains very high.”
