    This is bad: Twenty big cats die of bird flu at sanctuary in Washington state | Bird flu | The Guardian

    Twenty big cats, including a Bengal tiger, four cougars, a lynx and four bobcats, have died after contracting bird flu at an animal sanctuary in Shelton, Washington.
    ...
    The big cats died between late November and mid-December at the Wild Felid Advocacy Center, according to the center’s director, Mark Mathews.

    “We’ve never had anything like it; they usually die basically of old age,” Mathews told the New York Times. “Not something like this, it’s a pretty wicked virus.”

    Three other cats recovered from the virus, and one remained in critical condition on Tuesday. Last week, the center announced on Facebook that bird flu had affected more than half of its wild cats.
    ...

    Just in time, any comments about public health policies and staff changes would be redundant.

    Don't worry pal.

    They'll believe that the virus was 'wild caught' next time, too.

    Besides......
    You're a fairly new 2A convert.

    Started "Public health and Bird Flu" in Fred's House of Politics. Let's try to keep this thread technical.

    Per Google:

    As of December 24, 2024, there have been 61 reported human cases of H5N1 bird flu in the United States since April 2024:
    • California: 34 cases, including the first case in a child in the U.S.
    • Colorado: 10 cases
    • Louisiana: 1 severe case, the first in the U.S.
    • Michigan: 2 cases
    • Missouri: 1 case
    • Oregon: 1 case
    • Texas: 1 case
    • Washington: 11 cases
    Here are some other details about the H5N1 bird flu in the U.S.:
    The majority of cases have mild symptoms, such as a runny nose, coughing, eye redness, and inflammation.

    • No deaths have been reported in the U.S.
    • The risk to the general public is low, as long as they aren't exposed to infected animals.
    • The CDC is working with states to monitor people who have been exposed to animals.
    • The CDC recommends avoiding exposure to sick or dead animals, including wild birds, poultry, and other domesticated birds.
    • People should also avoid exposure to animal poop, bedding, unpasteurized milk, or materials that have been touched by birds or other animals.

    ps. Perhaps more details about "22A" as Google references a discontinued S&W 22 cal pistol and an obscure VA form.

    I have become somewhat anti-zoo over decades. Innocent prisoners on public display. Worst in squalid conditions though I'd better not name zoos. :eek:

    Balancing that are animal health research and assisted reproduction. Many species including some big cats have lost suitable living areas in the wild. Zoos to some extent represent 'you broke it you own it' of the animal world.

    ==

    Concerning bird flu
    "Worldwide, nearly 1,000 cases of illnesses caused by H5N1 have been reported since 2003, and more than half of people infected have died, according to the World Health Organization.”

    https://apnews.com/article/bird-flu-h5n1-spread-people-e5edab844b409b8ba21feaecb10156d0

    All are animal-to-human transfers in the sense that no human-to human-transfer has been found.

    There are H5N1 vaccines under development (both for animal and human use). If virus mutates such that antibodies induced by vaccine don't hit the new version, that would be bad.

    If human-to human-transfer gets going, but vaccine is not widely adopted (as we see in other circumstances), that would be bad.

    How is the development schedule of the under-development vaccines looking?

    At least two companies in US, elsewhere I don't know. Overall I'd say that workflow is in pretty good shape. Human vaccine trials are at zero and I expect that to consume much more time. If h-to-h transfer begins.

    The article was about big cats but there are articles about cat food recalls due to pets getting sick.

    As for zoos, at least the Trumps haven’t treated them like shooting ranges.

    UK has stockpiled 5 million vaccine doses even prior to human trials. There is also US stockpile of ??? size.

    One bad thing about this H5N1 is that virus is in bird poop. Very difficult to avoid exposure to that stuff.

    Interesting. I still plan to capture rain water for gardening and gray water. However, I am aware of UV water purification systems.

    Instead of chloride salts, a small pump passes the pool water by a strong UV source both killing any small critters as well as generating a dose of ozone which is also toxic to biology. But I had not considered how well a UV pool sanitizer would work with H5N1.

    UV-C with sufficient dose will 'do' all DNA including viral. Penetration of UV-C let's say 285 nanometers through clean water might be centimeters not meters. I find this to be a difficult search topic.

    "chloride salts" ... hypochloride! oxygen is important Baaaaaab

    Can’t avoid bird poop?

    I always anticipated a circulation pump. But the cost of pool units is too high and over capacity. Might have to build my own if a rain barrel size is not available.

    A roof esp. with overhanging trees is a bird poop collector. Avian poopologists seem surprised by the presence and amounts of virus therein. So, roof rainwater may merit special treatment.

    Also a micrometeorite collector, but not all magnetic particles are of extraterrestrial origin.

    Good news, rain barrel sized, UV systems:
    upload_2024-12-28_17-16-34.png

    Nice range of prices. Water usage is charged and used to calculate the sewage rate. This is the second highest part of the utility bill.

    Collect the rain water in a two stage system. First, mosquito net covered dome for gray and garden water. Overflow feeds into a second tank closest to the UV zone. Co-locate outside of the bathrooms:
    • Gray water - toilet flush and garden.
    • Potable water - sink and shower
      • Feed line to kitchen sink
