All viral isolates from the 11 patients in this series had been susceptible to both adamantanes and neuraminidase inhibitors . Dialogue In this record, we describe the scientific and epidemiologic characteristics of 11 cases of laboratory-confirmed infection with triple-reassortant swine influenza A viruses, which were identified and reported in the usa prior to the current epidemic of swine-origin influenza A viruses in humans. The patients’ exposures to pigs or their conditions varied broadly in setting and level, and almost half the patients had not touched pigs directly. The median incubation period was 3.5 days from the most recent contact with pigs or their environment, but in general it were than the incubation period for seasonal influenza longer.42 However, contact with a human with a triple-reassortant swine influenza A virus as the source of illness cannot be ruled out as a possible description for the apparently longer incubation period.
