Why does norovirus come in winter?
« on: 13/01/2009 13:38:22 »
Thesamies asked the Naked Scientists:
   HI, Do you know why we always have the Norovirus at this time of the year?

Where does it start from ? I do not remember this being such a problem when I was growing up and can really only remember this being a problem for the last 3-4 years ?
Tanya  Essex.

What do you think?

I suspect that it occurs more frequently in winter because people are generally huddled closer together and stay indoors more.
I remember Chris saying how easily it is to transmit from person to person.
I tried to find the article.. but my search skills are lacking.. sorry.
