U.S. Surgeon General Murthy: COVID variant presents 'unusual challenge' to CT Julia Bergman FacebookTwitterEmail In this July 15 photo, Surgeon General Dr. Vivek Murthy speaks during the daily briefing at the White House in Washington.Susan Walsh / Associated Press Connecticut residents should feel hopeful about the state’s progress in combating COVID-19, including its successful vaccination campaign, but the most transmissible version of the virus to date presents an “unusual challenge” to that progress here and elsewhere, U.S. Surgeon General Dr. Vivek Murthy said Tuesday. If “significant increases” in new Covid-19 cases occur in Connecticut in the future, and if over time those new cases are among vulnerable populations like children, who don’t have the ability to be vaccinated yet, “those would be circumstances where I would consider whether or not we need to take some additional mitigation measures,” Murthy said in an interview with Hearst Connecticut Media.
