The COVID-19 pandemic is affecting Thanksgiving holiday plans for many American families. The Associated Press reports that coronavirus cases are rising at a worrying speed across the United States. The Johns Hopkins Coronavirus Resource Center says the virus has killed over 250,000 people nationwide. Many people are getting infected every day. The U.S. Centers for Disease Control and Prevention (CDC) last week released guidelines on the safest way to celebrate Thanksgiving. The CDC is advising Americans not to travel over the holiday this year. And it is urging them against spending time with people from outside their immediate household. The warning is some of the firmest guidance yet from the CDC on how to limit the spread of the virus.
