Many people believe exposure to cold, wet or changing temperatures causes colds.
But studies don't show that. In fact, the cold virus spreads through respiratory secretions via coughing or sneezing, or through contact from contaminated hands, other skin surfaces, even table tops. To prevent catching a cold, avoid the coughs and sneezes of others, wash your hands often and keep your hands away from your eyes, nose and mouth. Early symptoms of other, more serious diseases can mimic those of a cold. Flu symptoms are similar to those of a cold, for example, except that flu sufferers usually develop fevers.
