There is some preliminary evidence suggesting the omicron variant is more infectious than the delta variant, says Bollinger. Some variations allow the virus to spread more easily or make it resistant to treatments or vaccines. We are not closing up shop. Neither are we closing down the management systems and the order of battle against the virus. We still have a lot to learn about omicron, Ray says, but we have tools at hand that enable individuals to manage risk, including wearing a high-quality mask, or respirators. I have not seen any data so far, Bollinger says, that would suggest that these drugs would work less well for omicron than for any of the other variants. Currently, the Centers for Disease Control and Prevention (CDC) has identified one variant of the virus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) as a variant of concern: In April, the CDC downgraded the delta variant from a variant of concern to a variant being monitored.
