  •  probably more trichinosis than flu (1+ / 0-)

    but you're right about them being 'mixing vessels' for flu. However, it's now theorized that 1918 was a direct bird to human problem, so there's more than one way to get there.

    •  Wow. (0+ / 0-)

      Ah well...you gotta die of something.

      I'm no where near panicing.  Just gotta deal with what life gives you.  No sense getting all worried about it.  But always a good thing to stay informed.

      Thank you,

    •  And there is now some concern (0+ / 0-)

      that cats can carry H5N1, and maybe infect their caregivers. But I suspect they were looked at because of the SARS connection, not because of any real epidemiology.

      If the Red Cross looks for antibodies to West Nile Virus in US blood donors, and I suspect they don't, they do PCR for virus, there may be many of us who have "seen" the virus, in that it was replicating in our bodies enough to cause an immune response that led to antibodies being made.

      DfCT, you would know better: are there any epidemiological studies about exposure to influenza H5N1 in poultry workers in areas that have had large bird epidemics? We all hear the "kill rate" in infected humans, but is there any evidence that some infections lead to mild disease? And if so, are there genetic tests being done to determine who might be so fortunate as to be relatively resistant to H5N1 as the various quasispecies exist now?

        we maintain a seroprevalence page at the wiki.

        Since the initial signs of human infection, scientists in Indonesia, Vietnam and Thailand have been studying those around the people who became infected, looking not only for signs of infection and increased transmissibility, but also for antibodies that could help to explain why some people became infected while others remained healthy.

        "The evidence for widespread asymptomatic infections is just not there,’‘ said Michael Perdue, a World Health Organization scientist working on the global influenza program. "The (more recent) studies that have been done, one of the reasons frankly that I think they haven’t been followed up on, is they haven’t found many positives. You don’t get too excited about all negative serology (blood work)."

        Dr. Scott Dowell, director of global disease detection and preparedness at the U.S. Centers for Disease Control in Atlanta, agrees: "If there was mild or asymptomatic H5 infection and that was relatively common and the severe cases we’re picking up were the tips of the iceberg, then if you look at family members or hospital contacts or cullers, you would expect to be seeing some of these.

        them eating chickens in the live bird markets in indonesia and because there were reports that 1 in 5 stray cats in these areas were infected and because tigers in a Thailand zoo were known to be infected (carnivores) and because the Dutch showed that cats could pass the virus to each other.
