It does affect the incidence of the common influenza and cold viruses. In Việt Nam where the women have traditionally covered up so as not to get any sun on their skin, these viruses are "women's maladies." Men go about bare armed and hatless a lot and do not get sick. That tropical sun is always at aan effective angle and the temperature does not get cold, at least in the south. In Hà Nội where it gets cold- welll cld as southern Alabama, men get viruses in the winter but less than women do.

This is not the flu. Has China ever shut down 750 million people because of the flu?
