Could childhood obesity be caused by a strain of the cold virus?

A new study finds at least part of the blame for childhood obesity might be traced to a certain strain of the virus that causes the common cold.

In the study in the online journal Pediatrics youngsters who were infected by adenovirus 36 were an average 50 pounds heavier than children who hadn't been infected by this particular strain. The number of children who had this infection was relatively small.

Scientist's say the finding raises a lot of questions like does the virus cause obesity or do obese children tend to have this virus more often?
