DEAR ABBY: Harry C. Williams Jr. of Nashville, Tenn., is right to be concerned about shaking hands with hospital patients. Some years ago as a journalist, I was assigned at the Centers for Disease Control in Atlanta. Once I went into an area where research was in progress. As I was introduced to the doctor I was to interview, I offered to shake hands. He drew away and explained, "We don't shake hands at the CDC." -- JACK STILLMAN, JASPER, GA.
DEAR JACK: How about touching elbows?
