The search for patient zero

CNN - 2009 could go down as the year of swine flu. It hasn't left a corner of the globe untouched.

Federal health officials say almost 10-thousand people have died from the
H-1-N-1 virus since April -and some 50 million Americans have caught the virus.

As the cases of swine flu build around the world, everyone has been on the hunt for the source.

Many have long suspected that the origins of swine flu may have been on
a pig farm about 2 hours north of mexico city.

A young boy named Edgar Hernandez, may be patient zero, the first patient to contract the virus.

La Gloria is a village, where everyone knows someone. After showing a motorcycle rider Edgar's picture, he offers to show us where he is.

After hours of driving and hours of searching we finally meet the little boy that everyone's calling patient zero.

"Did you have a headache?" Translator: "He had headache and sore throat."

He was brought to this clinic where he was diagnosed as possibly the first case
of swine flu. So where did it come from? Edgar's mom thinks she knows.

"A lot of people are saying the swine flu came from some of the pig farms. Do you believe that?" Translator: "That's what she hears."

One industrial pig farm is huge and owned by an American company called Smithfield Foods.

People in town say they believe this is the source of the outbreak.

So with this medical mystery now only half-solved. We know who may have first contracted swine flu. It is just not known where he got it.
