Jih-Haw Chou pointed out that the subjects separated by twice test H5N2, January 2nd H5N2 antibody concentration of more than 1 times 4 times, can be judged to be positive; Theoretically, these three people infected with the H5N2 avian influenza virus will antibody positive, but in practice can not rule out confounding factors.
He explained that three people last year, both the administration of seasonal influenza vaccine are immunized with the H5N1 avian influenza vaccine this year in March and April, the body H5N2 antibody-positive, but no symptoms of infection, it could be seasonal flu vaccine or cross-reactivity of H5N1 vaccine.
Japan had reported to staff and employees involved in the H5N2 avian flu prevention, in vivo detection of H5N2 antibody. Similar situation in Taiwan for the first time.
Changhua County Health Bureau of department said that blood testing when previously Changhua County outbreak of bird flu for more than 100 staff, only 3 showed positive reaction, does not extend on behalf of the bird flu, such as the spread of the disease The number of positive reactions should be more.
