They are caused by viruses pass ing on from pers on to pers on. You catch a cold by coming into con tact, directly or in directly, with some one who already has on e. If cold causes colds, it would be reas on able to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regi ons explorers have reported people are free from colds un til they come into con tact aga in with in fected people from the outside world by way of packages and mails dropped from airpla nes.During the First World War soldiers who spent long periods in the trenches （战壕），cold and wet, showed no in creased tendency to catch colds.In the Second World War pris oners at the Auschwitz concen tratio n camp, n aked and starvi ng, wereast oni shed to find that they seldom had colds.
