One is a combination of human and swine flu. The other is a triple reassortment of human, pig and avian strains. Though the new bugs have caused outbreaks exclusively in pigs, they serve as evidence of influenza's restless alterations. One way to stay a step ahead of this constantly changing threat, experts say, is to monitor strains in people and animals, especially wild ducks. Experts also advise simple strategies to reduce the risk that viruses will jump from one species to another.
Heat destroys influenza, so it's also wise to thoroughly cook duck meat.
Duck hunters who are farmers should wash and change clothes and boots after hunting before they come in contact with chickens, turkeys, pigs and other livestock. Wild ducks should never be cleaned in or near poultry houses or processing areas, because even small bits of fecal matter can transmit the virus. For the rest of us, the best defense against flu is an annual vaccine. But even if you simply want to make fairly sure to avoid the winter misery, get the flu shot, which has been shown to be about 88 percent effective in preventing the disease. It's only a matter of time.
