title: [Host and exacerbation factors related to influenza susceptibility].
abstract: The host factor of susceptibility to influenza are divided with two ones. First is HI titer (more than 40 or not) in each host according to the age groups to the prevalent influenza virus type. Second is the host conditions which mean high risk factors in influenza patients, especially CPE, lung fibrosis, the decreased lung-function patients and heart failure. I divided those patients with 5 groups from normal persons to high risk patients, and described the vaccine policy and the treatment procedures.
