Why young people are not safe from Covid-19 — Dr. Wen explains

There has been a worrisome trend emerging in recent weeks: Cases among younger people are rising. In Michigan, hospitalizations among people in their 30s have climbed by over 600%, and those in their 40s by 800%. Average daily cases for children have also risen by over 200%. In Massachusetts, the largest increase in Covid-19 infections has been in children and teens.

What accounts for these trends? We discuss with 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 the author of the upcoming book "Lifelines: A Doctor's Journey in the Fight for Public Health."
