Just when you thought you had nothing to worry about comes reports that the Center for Communicable Disease Control now believes that human to human contact was responsible for infection with a novel flu strain - previously indentified in Indiana, Maine and Pennsylvania.
The Indiana, Maine and Pennsylvania cases were thought to be acquired from contact with swine.
From Bloomberg News:
A new swine-flu variant infected three children in Iowa, spurring a search for more cases that may signal whether the virus is spreading easily among people.
The cases occurred over the past three weeks, causing a “mild” respiratory illness with fever, the Centers for Disease Control and Prevention said in a report today. All three children were in contact with one another, and none had a known recent exposure to pigs, the Atlanta-based agency said.
No more infections with the virus, dubbed S-OtrH3N2, have been found among Iowans and there is no evidence of sustained human-to-human transmission, the CDC said. Surveillance is ongoing, it said. Iowa is the biggest U.S. hog-raising state. Scientists around the world are searching for novel flu viruses to get a jump on ones with pandemic potential.

At least seven other people have been infected with the new swine-flu variant this year -- with three cases in Pennsylvania, two in Maine and two in Indiana, the CDC said.

From the CDC report:
The 2011--12 seasonal influenza vaccine is expected to provide limited protection from this virus for adults but none for young children. Enhanced surveillance, including surveillance for ILI and diagnostic testing of respiratory specimens, is being conducted in Iowa and surrounding states as part of the ongoing investigation of these cases.
