A child tests positive for H5N1

The California child is day care age and was showing symptoms while attending the day care so they are administering preventive treatment and testing of contacts.
The child had no contact with farm animals, and the source of the virus has not been determined.  They need to sequence it and determine if it is the dairy virus.  If it is the dairy virus, infection via dairy products should not be ruled out.  It would be just like the Missouri infection where there was no known source except that they had consumed dairy products.  I only saw the milk claim in one article, and it seems be suppressed at this time.  The child is only claimed to have had respiratory symptoms.
They tested the family members, but they need to do antibody testing in order to rule out that any of them had been infected since the child was late in the infection when tested (low amounts of virus) and was negative 4 days later at the next testing, a family member could have infected the child and recovered before being tested.  If they aren't going to test them properly they should contact trace the family members to determine if they can track back to a possible source of the infection.
They do not seem to be doing things that they should be doing.  The California report repeats the claim that pasteurization kills the virus, and it does, but they do not admit to the CDC research indicating that the the 72 degree C for 15 to 20 sec method of pasteurization did not kill the virus and some infective virus survived the treatment to be detected as infective virus.  The FDA is supposed to be doing more testing, but they don't seem to be doing it properly, and have not reported their results at this time.  The CDC results were reported in October, but no one is taking the results seriously, at least, no one wants to consider the possibility.  Has anyone else even heard of the CDC tests and results?  I only found out because they published the results in their November newsletter published in October.  I haven't seen anyone else citing that newsletter report.  In early November the FDA claimed that they were going to start another round of testing, but it didn't sound like they were going to do the testing the way that they should.  It is stupid to ask for volunteers and claim to just forget where the milk came from.  They need to test the milk out of each truck, and test the milk after pasteurization to see if any positive loads leaked viable virus, and they need to test each pasteurization method multiple times at multiple processing plants handling infected milk. This isn't rocket science and doing things with the intent to fail is just stupid.
What this article doesn't say is that San Francisco, San Jose, and Palo Alto have had H5N1 detected in their city waste water.  Look at were Alameda county is (the child is claimed to live in Alameda county). This child would have been putting virus into their city waste water.
