Many countries around the world have put in place stronger measures meant to control the spread of the new coronavirus.But these new restrictions are causing tensions because they affect holiday observances and traditions.In some places, celebrations of Christmas and other upcoming holidays are being limited or even canceled.Health officials in the United States worked hard to urge people to stay home over Thanksgiving, held on November 26.But many Americans chose to travel and gather anyway.On Twitter, Dr. Tatiana Prowell of the Johns Hopkins School of Medicine blamed the way the American people think.She wrote: "The U.S. ‘each person for himself' mindset is killing hundreds of thousands of us."In recent weeks, three drugmakers have announced promising results for effective vaccines against the new coronavirus.But an approved vaccine is unlikely to be widely available to the public for months.
