First detected last month in South Africa, the new Omicron strain of the coronavirus has been designated a “variant of concern” by both the World Health Organization and the Centers for Disease Control. Dozens of countries have detected Omicron infections, and in the United States, at least 16 states have reported cases. While scientists are still in the early stages of researching the new variant, early reports suggest that while Omicron may have greater transmissibility than other variants due to its unique set of mutations, it causes less severe symptoms than other forms of the virus.
