This makes the total 11 for California. It means that the other states have been severely under reporting cases, mainly because they are not testing and contact tracing. The cases need to be confirmed by the CDC, but the previous ones were verified, and California is likely using the CDC PCR test. It should have been fixed by now, and initially had issues with false negative results when the CDC first put it out, but they have had more than half a year to fix that test, and false negative results are not an issue for positive test results. 11 cases involving 9 farms. 2 cases were at the same farm, but it was a huge dairy farm (something like 5,000 cows) and the two workers worked at different parts of the farm, and did not have contact with each other. So it looks like all of them were infected by cattle. In a previous article California health officials claimed that they were tracing close contacts of the infected dairy workers, and would be testing those contacts if they exhibit symptoms. It won't be any surprise if they find close contacts infected because in both Michigan and Texas where they asked the question they found that twice as many close contacts of dairy workers worked at poultry farms or other dairy farms as the dairy workers themselves, and both Texas and Michigan had infected poultry flocks with the dairy virus. So they already have known for months that close contacts may have been spreading the dairy virus. The CDC just never implemented testing and contact tracing. Ron Okimoto
