Missouri antibody results

6 of the 7 hospital contacts had their serum tested, but all were negative.
The patient and one family member that had shown similar symptoms tested positive for 2 of the 3 H5N1 antibody tests indicating that they had similar infections.  The CDC is claiming that there is no evidence for person to person transmission, and that both family members could have been infected from the same source.  This source is not known since they had no contact with sick birds nor cattle.
So 2 people in Missouri were infected by the dairy influenza, but they do not know the source of the infection.  My guess is that they shared the same bottle of milk, and that dairy products in Missouri need to be tested in light of the recent CDC results indicating that the virus may survive the most common method of pasteurization.  Both family members exhibited evidence of gut infection.  The Asian H5N1 strain has been known to cause diarrhea in human patients that had injested infected goose blood.
