As Covid-19 cases are surging across the United States again, daily infection rates are at their highest levels since February, due in large part to the very contagious Delta variant.
The US Centers for Disease Control and Prevention has once again urged a return to indoor mask-wearing, citing that even vaccinated people can get infected and pass Covid-19 to others.
Meanwhile, many people have travel plans for the rest of the summer and the upcoming Labor Day holiday weekend. Should they cancel their vacations? Is air travel safe? What if they are getting together with extended family or friends over the holiday — what precautions need to be taken? And what about families with children too young to be vaccinated?
To help answer our many questions about travel and Covid-19 safety, we turned to CNN Medical Analyst Dr. Leana Wen. Wen is an emergency physician and visiting professor of health policy and management at the George Washington University Milken Institute School of Public Health. She’s also author of a new book, “Lifelines: A Doctor’s Journey in the Fight for Public Health,” and the mother of two young children.
