Is Omicron as serious a health risk as other variants? Is it more or less contagious?

Health officials are collecting data to be able to answer these questions. In the meantime, it is important to remember that any coronavirus infection can be life threatening especially in people with underlying medical conditions. The best way to prevent the spread of this new variant or any other variant is to get vaccinated, get a booster if you are eligible, and to wear a mask in indoor public settings or in a crowded environment. In most places, masking is also required for air, train and bus travel and other forms of public transportation.
