The CDC mainatins a website on swine origin influenza virus (SOIV) in humans.

http://www.cdc.gov/flu/swineflu/soiv_cases.htm

ther last update of the text was in January, but the site is updated with links to MMWR reports on influenza updates, which include a section on novel influenza infections. The last such MMWR update was June 3, 2011,
http://www.cdc.gov/mmwr/preview/mmwrhtm ... mm6021a5_w
entitled Update: Influenza Activity --- United States, 2010--11 Season, and Composition of the 2011--12 Influenza Vaccine
This report details the trH3N2 cluster in Minnesota, but is not linked to the CDC SOIV site.

From above MMWR report:

Novel Influenza A Viruses

Five cases of human infection with a novel influenza A virus were reported during the 2010--11 influenza season from three states. All five cases were infected with swine-origin influenza A (H3N2) viruses. Two cases occurred in September (Pennsylvania and Wisconsin), one case in October (Pennsylvania), and two cases in November (Minnesota). Two of the five cases occurred in adults, and three occurred in children. Two of the five cases were hospitalized; all five have recovered fully from their illness. The two cases in Pennsylvania were not related. The cases in Wisconsin and Pennsylvania had direct contact with swine or lived in areas close to swine farms. The two cases from Minnesota occurred in a father (index case) and child. The father had a nasopharyngeal swab positive for swine-origin influenza A (H3N2) virus and had direct swine exposure 6 days before illness onset. The child, whose infection with influenza A (H3N2) virus was confirmed several weeks later by serologic testing, did not have direct swine exposure, and most likely acquired infection from close contact with her father. Other persons in the same household also had ILI during the same period, but serologic results were either negative or inconclusive.

The updated CDC site has strategically ignored the MMWR report on the Minnesota cluster

Reported Human Infections with Swine Origin Influenza Viruses (SOIV) in the United States since 2005
As of January 25, 2011, 20 cases of human infection with swine origin influenza viruses (SOIV) have been reported in the United States. These are viruses that normally infect pigs. Like human influenza viruses, there are different subtypes and strains of swine origin influenza viruses. The main swine viruses circulating in U.S. pigs in recent years are swine triple reassortant (tr) H1N1 influenza virus, trH3N2 virus and trH1N2 virus. Of the 20 human cases reported since 2005, 12 have been trH1N1 viruses, seven have been trH3N2 viruses and one has been a trH1N2 virus. All 20 persons infected with swine viruses recovered from their illness. Thirteen cases occurred in children (persons younger than 19) and 7 cases occurred in adults. In 16 cases, direct or indirect exposure to swine prior to onset of illness has been identified. Although no person-to-person transmission of swine influenza viruses has been laboratory confirmed in the investigation of these cases to date, some cases reported only exposure to ill persons and no exposure to live pigs. Thus, limited person-to-person is likely to have occurred.

This statement is FALSE. The daughter of the Minnesota index case (31M) was lab confirmed (serologically) to have been trH3N2 infected and has no link to swine.
