Concerned I may have been exposed to whooping cough


Q: I had dinner at a friend's house last night and his 10-year-old son had a deep chest cough that would start and stop at regular intervals. The kid covered his mouth with his hand most of the time. Apparently he has been coughing for about 1 week and is taking children's cough medicine every night. I have not experienced any symptoms of my own since last night and no one else in my friend's family has gotten sick yet, but I read that it sometimes takes a week or 2 for symptoms to develop. What can I do in the meantime?

Symptoms:  Coughing
