6 more herds infected in Idaho and 1 more herd infected in Utah.
The USDA should give the number of reinfected herds so that the
true extent of the current epidemic can be evaluated.-a 53 total
herds newly infected in 2026 (Mostly in Idaho, but also in Texas
and Utah).-a 33 herds in the first couple of weeks in June.-a The
usual quarantine is obviously not working in Idaho.-a There can't be >>>>> that many herds left that have not been infected at least once
since the state was first infected in 2024. They likely have to
start restricting dairy worker movements from infected farms, and
start contact tracing and testing dairy workers and their human
contacts. As crazy as it may be it is still only a recommendation
that dairy workers on infected farms should not work on other
farms.-a It has been known since 2024 that around 10% of the dairy
workers on infected farms were getting infected, and the research
dairy virus line was cultured from eye swabs of the first Texas
infected Dairy worker.-a A lot of dairy workers are getting infected >>>>> and they shed live virus.-a It was just stupid that they essentially >>>>> stopped testing dairy workers after the found out that so many of
them were getting infected. The CDC claimed that they were going to >>>>> start a testing program, but that never happened, and they still do >>>>> not do contact tracing to determine how the new herds are getting

movements are restricted?

Another dairy herd infected in Idaho.-a That makes 30 new herds
confirmed to be infected in June.-a The rate of increase means that
they are likely not restricting dairy worker movements.-a This
includes veterinarians that are known to have been infected in the
past.-a If they had started contact tracing in 2025 they likely could >>>> have avoided these herd infections.
It is crazy that they are still not requiring dairy worker
quarantine. Restricting cattle movement is obviously not working.
The denial for political purposes is just stupid.

A new Texas herd has been added to the link above.-a Both Utah and
Texas had been classified as "unaffected" (bulk milk tank negative
for 6 months) and now both states have multiple herds affected (2 in
Texas, 3 in Utah).-a The USDA has not counted reinfected herds so the
extent of the infections may not be known.-a Reinfected herds have not
been listed in the data set at their confirmation site.
Ron Okimoto
influenza/hpai-detections/hpai-confirmed-cases-livestock
Two more herds, one in Idaho and another in Utah have been confirmed
to be infected.-a Since the USDA does not report reinfected herds the
true extent of the epidemic in Idaho, Utah, and Texas is not known.
No information as to how Utah and Texas were reinfected, and no
information on the genetic relationship of the virus infecting the
three states. The dairy epidemic seems to be restarting with over 30
new herd infections in June and 57 total in 2026.-a 171 new herd
infections were confirmed in 2025, but the USDA did not count herds
that had been infected, cleared the virus, and were subsequently
reinfected, so the true number of herd infections in 2025 is not
known.-a California, Colorado, Minnesota, and Texas are states that I
know reported reinfected herds in 2025 at the state level, but these
herds were not counted as confirmed infected by the USDA.

7 more herds infected in Idaho (64 total herds infected in 2026, 44 in
June)
It is probably time that they considered dairy workers as transmission vectors.-a Idaho, Utah and Texas are still not requiring dairy worker quarantine onto infected farms.-a It remains only a recomendation that
dairy workers not be allowed to work on other farms.-a Cattle movements
are restricted, but 45 herds have been infected in the last 30 days in
three states with Utah and Texas having had attained unaffected status
(bulk milk tank testing negative for 6 months) by May before being reinfected.-a It is just crazy that they never started dairy worker
testing and contact tracing when they knew from the first infected dairy worker (March 2024) that he was shedding live infective virus.-a They understand that around 10% of the dairy workers on an infected farm get infected (likely more than that because they tested the dairy workers
before the farms had cleared the virus, so 10% were the ones that had
been infected at the time of testing).-a They knew that infected workers shed infective virus, and they knew that a dairy workers from an
infected dairies worked on more than one farm including poultry farms.
In Michigan one dairy worker from an infected dairy had also worked on
one of the Michigan commercial layer farms that was infected by the
dairy virus.-a They never tested the dairy worker nor followed up to determine what dairy the virus that infected that poultry farm came
from.-a The virus may only be infective on skin and clothing for a matter
of hours, but noting will keep the birds from being infected if the
worker is shedding live virus.-a Changing clothing, and even showering before entering the farm will not protect the birds from an infected worker.-a California lost 40% of their commercial layer flocks, and never restricted dairy worker movements.
It is just nuts that the virus is being allowed to continue spreading to
new herds and other states.-a Veterinarians have to be included among
dairy workers because 3 veterinarians were found to have been infected
at some conference where blood samples were collected and none of them claimed to have experienced symptoms, but they had obviously mounted an immune response, so they were likely shedding virus at some time.
