ATLANTA — The U.S. Centers for Disease Control and Prevention (CDC) have confirmed three cases of a new flu virus, according to USA Today.

The virus originated in pigs but has spread from person to person, infecting three Iowa children, the article stated.

According to the article, the CDC says, however, that this is not the beginning of another widespread pandemic.

"I don''t think this is anything to worry about for the moment," said Arnold Monto, a flu expert and professor at the University of Michigan''s School of Public Health.

"We have known that swine viruses get into humans occasionally, transmit for a generation or two and then stop. The issue is whether there will be sustained transmission (from person to person) — and that nearly never happens," Monto added.

The CDC has counted a total of 18 cases of this new virus, an influenza A strain known as S-OtrH3N2, in two years, which suggests that it''s not spreading quickly or easily, the article noted.

The 10 cases of H3N2 in 2011 also have been spread throughout the U.S. — in Pennsylvania, Maine, Indiana and Iowa — which doesn''t indicate a disease "cluster" or outbreak, the article added.
