Nearly a dozen cases of the omicron coronavirus variant have now been detected around the United States, with many of them confirmed in New York on Thursday.

New York and Hawaii are the latest to announce infections, and officials in both states said there is evidence of “community spread.” Cases have also been detected in California, Minnesota and Colorado. The Minnesota patient recently attended a New York City convention that drew thousands of people.

Health officials have been bracing to discover more infections since the first reported U.S. case was announced Wednesday.

“This is not a cause for major alarm,” New York Gov. Kathy Hochul (D) said at a news conference, urging people to wear masks, get vaccinated and get booster shots.

  • People will be required to wear masks on airplanes, trains, buses and other transportation through March 18, according to senior Biden administration officials.
  • All international travelers must take a coronavirus test one day before their flight to the United States, starting Dec. 6.

Coronavirus: What you need to know

Vaccines: The CDC recommends that everyone age 5 and older get an updated covid booster shot. New federal data shows adults who received the updated shots cut their risk of being hospitalized with covid-19 by 50 percent. Here’s guidance on when you should get the omicron booster and how vaccine efficacy could be affected by your prior infections.

New covid variant: The XBB.1.5 variant is a highly transmissible descendant of omicron that is now estimated to cause about half of new infections in the country. We answered some frequently asked questions about the bivalent booster shots.

Guidance: CDC guidelines have been confusing — if you get covid, here’s how to tell when you’re no longer contagious. We’ve also created a guide to help you decide when to keep wearing face coverings.

Where do things stand? See the latest coronavirus numbers in the U.S. and across the world. In the U.S., pandemic trends have shifted and now White people are more likely to die from covid than Black people. Nearly nine out of 10 covid deaths are people over the age 65.
