Can anyone explain what this study is actually saying? A lot of it seems to fly in the face of how people generally think diseases like flu are spread.

>studies done during Spanish Flu where sick people coughed directly in the faces of healthy volunteers, none of them contracted flu
>supposedly there's no real evidence that sick individuals with flu spread the disease to others
>Cold and flu infection rates are closely related to Vitamin D levels in the population
What does it all mean?
