Swine Flu (cont.)

Prevention of H3N2v Infections

The following are the 2013-14 CDC recommendations about avoiding H3N2v flu. The CDC suggests that these actions can reduce the risk of influenza viruses spreading from pigs to people, since there is no commercially available vaccine for H3N2v flu.

  • Don't take food or drink into pig areas; don't eat, drink or put anything in your mouth in pig areas.
  • Don't take toys, pacifiers, cups, baby bottles, strollers, or similar items into pig areas.
  • Wash your hands often with soap and running water before and after exposure to pigs. If soap and water are not available, use an alcohol-based hand rub.
  • Avoid close contact with pigs that look or act ill.
  • Take protective measures if you must come in contact with pigs that are known or suspected to be sick. This includes minimizing contact with pigs and wearing personal protective equipment like protective clothing, gloves, and masks that cover your mouth and nose when contact is required.
  • To further reduce the risk of infection, minimize contact with pigs in the pig barn and arenas.
  • Watch your pig (if you have one) for signs of illness and call a veterinarian if you suspect it might be sick.
  • Avoid contact with pigs if you have flu-like symptoms. Wait seven days after your illness started or until you have been without fever for 24 hours without the use of fever-reducing medications, whichever is longer. If you must have contact with pigs while you are sick, take the protective actions listed above.
