Is it because we are immunosupressed or coz we huddle close together more, or both?
Also, if they like the cold why do they do so well in human body which is very hot, 36degrees?
thanks

probably mainly due to people spending more time indoors with others. But also some evidence that in temperate regions, people's Vitamin D stores are depleted in winter (less sunshine). This may slightly weaken their immune system
Although they might survive slightly better in cool, dry conditions, they cannot reproduce outside a host cell (viruses have to use the biochemistry of the host cells to reproduce). They have adapted so their reproductive phase can go ahead in the conditions of the host organism - if it didn't they'd never reproduce.
