New virus making people gain weight

Doctors are now warning getting fat could be as easy as catching the common cold.

Researchers say the virus A-D 36 is highly infectious and contagious. It infects the lungs, whips around the body, and then forces fat cells to multiply. That can ultimately cause obesity.

Right now, doctors say, it's pointless to try and avoid infection since it is like the common cold, and there are no vaccines.
