    Swine Influenza Detected in Jackson County


    DHHR's Bureau for Public Health (BPH) and the Jackson County Health Department are investigating several reports of individuals who have developed influenza-like illness after working closely with swine exhibiting respiratory symptoms and fever at the Jackson County Fair. DHHR’s Office of Laboratory Services returned presumptive positive influenza A H3N2v on at least one human specimen on Tuesday, August 2. The sample has been forwarded to the Centers for Disease Control and Prevention for confirmation.
    “If experiencing symptoms such as fever, runny nose, sore throat, cough or congestion, it is extremely important to let your healthcare provider know if you or your loved one has visited a recent outdoor event with animal livestock, such as pigs, and to be appropriately evaluated,” said Dr. Ayne Amjad, DHHR’s State Health Officer and BPH Commissioner. “These symptoms usually show up 1-3 days after exposure.”Swine influenza viruses may circulate in pig populations throughout the year and do not usually infect humans. Although influenza viruses can spread between pigs and humans in rare situations, this usually occurs after having contact with a pig in a public setting or by directly working with infected pigs. The same influenza antiviral drugs used to treat seasonal influenza can also be used for treatment of swine flu infection in humans.State residents are encouraged to take routine precautions when visiting animal exhibits, including washing hands with soap and water before and after exposure to animals, to not take personal items, food or drinks into swine barns or areas with animals, to avoid close contact with animals that are ill, and to avoid contact with pigs if experiencing influenza-like symptoms.Resources and additional information:Swine Influenza (Influenza in Swine) | CDCInformation for Fair Organizers and People Exhibiting Pigs | CDCInformation for Pork Producers and People Who Work With or Raise Pigs | CDC

    CDC releases more information on West Virginia swine flu cases
    From Staff Reports 9 hrs ago

    ...An investigation into this situation has found that pigs at the fair tested positive for the swine influenza A H3N2 virus; all three human infections were with flu A H3N2v viruses based on RT-PCR testing and virus sequence analysis done at CDC; CDC genetic sequencing data indicates that the three flu viruses found in specimens obtained from the infected people are more than 99% identical to those obtained from infected pigs at the same fair; all three infections were in people younger than 18; none of the patients were hospitalized and all have recovered from their illnesses; and two of the three infected people had direct contact with pigs.

    The CDC will conduct additional laboratory tests on these three variant flu viruses, including analysis to determine whether flu vaccines stockpiled in case of a future flu pandemic or seasonal flu vaccines would protect against infection and severe illness with these viruses...
