Omicron is more transmissible than Delta variant: CDC Director

United States Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky said that Omicron is more transmissible than Delta variant. “Early data suggest that Omicron is more transmissible than Delta, with a doubling time of about two days. At least 36 states and over 75 countries have reported confirmed cases caused by the Omicron variant. And yesterday, CDC released data that estimate the prevalence of the Omicron variant based on our national genomic sequencing analysis,” she added.
