The CDC knew in May that dairy workers were infecting their own cats.

For some reason the CDC is finally releasing a report where the conclusion should have been that the two domestic cats got the virus from infected dairy workers.  For some stupid reason they claim that the workers refused to be tested, but one admitted to likely being infected by milk splashing in his face at the infected dairy where he worked.
This report is just sad, and should have been release months ago, and the stupid conclusions should have been used to contact trace dairy workers whether they wanted to be tested or not like California did to identify more infected dairies and stop them from infecting poultry farms where they also worked.
The obvious conclusion is that the workers were infected and managed to infect their cats, but did not infect others in the households of one of the workers.  The other lived alone with his cat.
Why has it taken 9 months to release this information.  The USDA release the fact that two dairy workers working at infected dairy farms also worked at two of the poultry farms that got infected back in June. Nothing was done then to identify infected dairy workers and make sure that they did not go to other farms.  California did not restrict dairy worker movements and ended up with nearly all the dairies in the state infected even though contact tracing had worked in finding more infected farms and they had identified several infected dairy workers early in the California dairy epidemic.
The denial of how this virus spreads to poultry flocks and other dairy herds is just stupid at this time.
