There are some steps you can take to avoid catching a cold. Contrary to popular belief, colds are not caused by exposure to severe weather. Colds are caused by viruses in the body, and you are better off out on the ski slopes or even waiting for the bus on a snowy day than you are in a cozy room, surrounded by friends, or fellow students, who just may be sick. A chill is an early sign of illness. It’s the cold that caused the chill, not the other way around.
While the virus can spread through droplets (微滴) propelled into the air when a cold sufferer coughs or sneezes (打喷嚏), surprisingly, this is not the most common route of transmission. Numerous studies have now shown that the majority of colds are caught by hand contact.
Cold viruses also can be transferred to objects -- telephones, towels, plates -- and remain infectious for up to three hours. Frequently hand-washing on the part of the cold-sufferer as well as other members of the family will minimize the spread of viruses in this way.
