http://www.news-medical.net/?id=15686A study by scientists at the University of Wisconsin-Madison, has found that the human adenovirus Ad-37 causes obesity in chickens.
The finding supports evidence from other studies that two related viruses, Ad-36 and Ad-5, also cause obesity in animals.
According to Leah D. Whigham, the lead researcher in the new study, human adenoviruses may cause human obesity, but more research is needed before a screening test and vaccine become reality.
She says there is mounting evidence that certain viruses may cause obesity, in essence making obesity contagious, but the viruses that cause human obesity need to be identified before a screening test and vaccine can be developed.
