The coronavirus might be receding in much of the United States, but it continues to spread in communities with low Covid-19 vaccination rates, where highly contagious virus variants pose a threat to those who have not had shots. In Smith County, Tenn., where only 20 percent of people are fully vaccinated, there has been an almost 700 percent increase in hospitalizations for Covid-19 over the past two weeks, according to a New York Times database.
