What can we do to avoid catching or transmitting a cold?
Avoid contact with people who have a cold, specially when they have just caught the infection - though sometimes it is possible to catch a cold from someone who doesn't yet know that he or she has a cold.
Avoid spending much time with many people in places without adequate ventilation.
If you have a cold, wash your hands well and often, especially after wiping your nose. Cover your nose and mouth when you sneeze or cough.
