The U.S. Centers for Disease Control and Prevention (CDC) have reported that since August 2011, 309 cases of H3N2v influenza infection of people have been reported in13 states.
To date, the states affected (and the number of cases reported in each
state) are Hawaii (1); Illinois (4); Indiana (140); Iowa (3); Maine (2); Maryland (12); Michigan (5); Minnesota (2); Ohio (102); Pennsylvania (14); Utah (1); West Virginia (5); and Wisconsin (18). No deaths have been reported. For the cases reported in 2011, there was limited human-to-human transmission, but in all of the 2012 cases for which contact information was present, people reported contact with swine and/or attendance at a fair at which swine were present. According to a recent report from the CDC, no evidence of sustained community spread of H3N2v has been detected.
This shouldn't prevent you from attending fairs with animal exhibits, but it does mean that you should take precautions to protect yourself and your family. These precautions should be taken any time you are in contact with animal exhibits, regardless of whether or not you're in an area currently affected by this outbreak. And these precautions are recommended for any animal exhibit, but are particularly important when visiting swine (pig) exhibits.
To date, people infected with H3N2v influenza have shown signs indistinguishable from seasonal flu: fever, coughing, sneezing, sore throat, runny/stuffy nose, body aches, headache and fatigue. If you are showing any of these signs of illness, particularly after visiting an animal exhibit, notify your healthcare provider.
At this time, we are not aware of any pets infected or sickened by the H3N2v influenza. However, the 2009 pandemic H1N1 influenza virus was transmitted to a smalll number of pets by their ill owners and it is best to consider this a possibility with this virus until proven otherwise.
This influenza is not transmissible to people or pets through properly handled and prepared (cooked) pork and pork products.
