The dazzlingly spreading Omicron variant now accounts for nearly three-quarters of new COVID-19 cases in the United States, data released Monday by the Centers for Disease Control and Prevention (CDC) said.
According toCDC, the proportion of new cases attributable to this new variant has now reached 73.2%, compared with only 26.6% for the Delta variant.
A sign of its phenomenal transmissibility, it only took 19 days after the first case of Omicron detected on American soil for the variant to become the dominant strain in the country.
By way of comparison, the Delta variant, which had become dominant in early July, had been identified for the first time in the United States in the spring. It was considered twice as contagious as the previous variants.
