"If you yourself have a cold or if other members in the family have a cold, they should wash their hands," said Dr. Jon Abramson, who was interviewed for the ABCNews.com OnCall+ Cold & Flu resource center.
"Also, when you're coughing or sneezing, you should cover your face with either your hands or your elbow," said Abramson, chairman of the department of pediatrics at Wake Forest University Baptist Medical Center.
Hendley has similar advice: "When somebody at my house has a cold, I'm not prepared to treat the surfaces, but I sure as hell wash my hands before I stick them in my nose or eye."
