According to the CDC, approximately one out of 10 people with severe disease die. Approximately half of the people who survive severe disease have long-term health problems. These can include recurring headaches, loss of muscle mass and strength, or memory problems
Anyone can develop severe illness, but the CDC says older adults, children, and people with weakened immune systems are at the highest risk
