There's A New Subvariant. How Concerned Should We Be?

Health experts are warning an even more contagious subvariant of Omicron, known as BA.2, could soon lead to another surge in Covid cases here in the U.S. The variant has already driven cases to skyrocket in China and Europe, which has historically served as a preview to the pattern the U.S. has seen throughout the pandemic. This comes at a time when protection from booster shots is waning for most people who got them. Dr. Jen Caudle, Family Physician & Associate Professor at Rowan University, explains what we can do to protect ourselves against the new variant and how we should act as warnings of another surge rise.
