ST. PAUL, Minn. (AP/WCCO) — The Minnesota Department of Health has linked another case of a new swine flu strain to the Minnesota State Fair.

According to MPR, a teenage boy developed a flu-like illness after he returned home, and later tested positive for a variant strain of H1N2. He had exhibited a pig at the fair.

The new flu strain contains a piece of the gene from the human pandemic virus that circulated globally in 2009.

All four people who have contracted the virus in Minnesota had exhibited or had family members who exhibited pigs at the State Fair.

This new flu strain is different from another swine flu linked to farms and fairs that has sickened nearly 300 people in the U.S.
