Two California dairy workers have been confirmed to have been
infected by the H5N1 dairy virus. Both were dairy workers. It
was expected because California has had the highest herd
detection rate because they have been tracking dairy worker
contacts from infected herds, and have been identifying infected
herds before the dairy farmers had detected symptoms. It has
been likely that dairy workers were spreading the virus to
poultry farms since the beginnings in Texas. The virus only is
infectious off clothing or skin for less than 30 minutes, and
they knew that poultry farms and states like Kansas did not get
infected cattle. Infected dairy workers have likely been
spreading the virus from the beginning.
California was not testing the dairy workers, they were only
tracking their contacts. These two had the eye infection
symptoms, and were tested.
The CDC is still claiming the danger of human to human infection
is low, but the more herds infected the more humans will be
infected, and the greater the chance that the virus will mutate
into something much worse. They are claiming that this isn't
evidence for person to person transmission, but that isn't the
major issue with infected herds. It is the virus evolving to
better infect humans that is the issue that they should be
trying to control, and the CDC refuses to do anything about that.
California is trying to detect all the infected herds as quickly
as possible, and they are using possible human transmission to
other farms to do it, and it is obviously working. Over 50
herds have been detected nearly all in the last couple weeks.

The Asian strain of H5N1 killed dozens of big cats at two zoos in
Vietnam. 47 tigers, 3 lions and 1 panther died. The dairy H5N1
is a recombinant virus and half of it's genome is from a North
American strain of Avian influenza, but it still is lethal to
cats. In the US the cats have been dying of brain infections.

The CDC is still claiming that human infections are rare, but that
likely was never the case. The CDC still has tested less than 250
people when thousands have been in contact with infected cattle or
close contacts of dairy workers. My take is that the spread from
herd to herd and poultry farms can be explained by an infection
rate of around than 5% among dairy workers, but the Colorado
poultry workers (6 of them) were infected at the same farm dealing
with the dairy virus infecting a layer flock. These poultry
workers were wearing protective gear, but it wasn't enough. The
dairy virus seems to infect the patients eyes, so you pretty much
need to wear a gas mask like face protector to keep from getting
infected.
As stupid as it may be the CDC is still advising people to wear
protective equipment when dealing with infected animals, but they
refuse to identify all the infected herds so that the people will
know when they should wear the protective gear.
The CDC is really supporting their failing program, and refuse to
admit that they have been wrong for months. They never started
contact tracing, and testing dairy workers. They never attempted
to identify all the infected herds even though their advice to
dairy workers about wearing protective gear depended on
identifying infected herds. California has demonstrated that
contact tracing works in detecting infected herds even if the
dairy workers are not tested. They have known that more states had
infected herds, but refused to start testing in those states. It
has been obvious since May that Florida had infected herds.
Positive dairy products were produced in Florida (FDA testing)
even though Florida is several states away from Carolina and Texas
(states known to have infected herds) and the CDC's own waste
water data indicated that some Florida counties had exceptionally
high levels of influenza in their waste water. No one went to
those counties to test the dairies, nor track back the milk source
of the positive dairy plant that produced the positive dairy
products. Dairy workers have been exposed to the virus in
Florida, at least, since May and they are not testing, nor are
they requiring protective gear to protect the dairy workers from
being infected. Florida is just one of the states that has not
admitted to having infected herds at this time.

The US is putting 72 million into getting pharm companies started
in producing a flu vaccine that includes H5. The latest Missouri
case indicates that this is wasted money. That patient had an H5
gene with 2 amino acid substitutions in it that supposedly reduces
neutralizing ability of H5 antigens 10 to 100 fold. The CDC is
currently allowing the virus to spread among dairy cattle and dairy
workers, and the virus is obviously mutating. What we will need is
a vaccine that works against the version of the virus that
eventually adapts to better infect humans.
They should have been identifying all the infected herds and trying
to limit the spread of the virus from the beginning. California
indicates that contact tracing dairy workers even without testing
them can identify infected herds, but the CDC never started contact
tracing, nor a testing program for dairy workers. Infected dairy
workers have likely been the primary vector for spreading the dairy
virus to other herds and poultry farms. As the virus spread it
mutates, so any attempt to make a vaccine at this time will likely
fall short of making an effective vaccine against what will
eventually become the next pandemic virus.
Really, only two herds in Michigan got infected cattle from Texas,
and it was likely spread to multiple counties and dozens of herds
by dairy workers. The Michigan survey of dairy workers told them
that it was common for dairy workers to work at more than one dairy
farm, and some of them worked at poultry farms. Michigan lost
several very large flocks of layers to the dairy virus, and dairy
workers likely infected the first flock while the other flocks
shared poultry workers.
