Omicron Becomes Dominant Variant
The Centers for Disease Control and Prevention (CDC) declared yesterday that cases of the Omicron variant now make up 73% of new COVID-19 infections in the United States, making it the leading variant in only three weeks since it was first identified in the U.S. on December 1. In certain parts of the country, the Omicron strain constitutes over 90% of new infections. Also yesterday, officials from the Harris County Public Health Department in Texas announced what is believed to be the first Omicron-related death in the U.S. The unvaccinated man, who had previously contracted the coronavirus, was over 50 with other underlying conditions. Health officials continue to caution that while Omicron initially appears to cause less-severe illness, its ability to evade human health defenses and high transmissibility are still reasons for concern.
