Cold and Flu

Is there any way to prevent a cold?

DEAR DOCTOR K: Is there any way to prevent a cold?

DEAR READER: The typical cold is a relatively mild misery that goes away without special treatment after about a week. Still, it's a misery most of us would rather avoid. Colds are caused by viruses — more than 200 different types. Because the infection is not bacterial, antibiotics don't help. Over-the-counter cold medicines are available, but not always effective.

Can sinusitis be prevented?

DEAR DOCTOR K: Every winter I come down with sinusitis. Is there anything I can do to prevent it?

DEAR READER: A lot of people suffer from periodic sinus infections (sinusitis). I'm one of them. The symptoms are aggravating: headache, pain or pressure in the face and head, where the sinuses are, and thick mucus clogging the nose. The good news is there are many things you can do to reduce your risk of sinusitis.
