Obesity 'can be caught like a cold'

The London Telegraph reports:

Evidence that obesity could be contagious was published yesterday by American researchers - and washing your hands could be an elementary step to avoiding the virus and becoming overweight.

A team led by Dr Leah Whigham, of the University of Wisconsin, Madison, found that the human adenovirus Ad-37 causes obesity in chickens, marking the third virus to be linked to being overweight: two related viruses, Ad-36 and Ad-5, also cause obesity in animals.

Is that virus going around Chicago?
