Myrtle Beach has the issue of young groups hanging out en mass at the local shopping centers and hot spots, that is recipe for COVID infections. Two youth groups from WV went down there and brought it back to WV. Horry Co. has a big time issue in the long term care facilities as well.
Wear a mask, social distance, don't put yourself or family in situations that might compromise everyone and things will be fine. I know two doctors families that just came back from the MB area and they are fine. Common sense stuff.
