<P> The source of the virus is revealed to viewers . A bulldozer ( coincidentally , operating for the company Emhoff worked for ) clears some jungle and disturbs some bats , with one finding shelter and food in a banana tree . That bat then flies over a pig pen , dropping a chunk of banana from its mouth , which is then eaten by a piglet . A chef from the Macau casino chooses the piglet and returns to the casino . As he handles the carcass in the kitchen , getting abrasions on his hands , he only wipes his hands when called to meet a customer -- Beth Emhoff . The chef shakes hands with Beth ( Mitch views the handshake on her camera in a previous scene ) , giving her the mix of bat and pig viruses , making the chef patient zero and Beth the second case . </P>
