-
- The identification of the 1st case of H1N1 in swine in
Japan provides a strong argument for routine, active surveillance
in animal populations when there is human disease actively occurring
in the area. As of last July (2009), Japan had more than 1200 cases
in people.
-
- The transparency in animal health status displayed in
the case is exemplary. Japan has recently encountered its 8th case
of oseltamivir resistance in people. - Mod PC
