Scientists' portrait of Omicron is still blurry and it will take weeks before they can fully assess its properties. That means that, in addition to staying up-to-date with their vaccines, people were advised to practice such strategies as washing hands, wearing masks, and maintaining a physical distance from one another, especially when indoors in places where there was substantial or high transmission.
