In order to clarify the incidence of importation of enteroviruses, we tried virus isolation from the stool of 181 oversea passengers with diarrhea and from the sewage of planes arrived at Nagoya International Airport from 1983 to 1985. To disclose the extent of dissemination, antibody prevalence to the serotypes of the isolated enteroviruses was studied in sera collected from residents of Aichi Prefecture. 1. In the three year period from 1983 to 1985, two strains of enteroviruses, echo type 1 and type 29 were isolated separately from toilet sewage of 42 planes. Both planes were from Philippines. 2. Five strains; Cox. B4, B5, 2 of echo 1 and unidentified virus were isolated from the stool of the passengers. 3. These five strains were isolated from Japanese, who had traveled Southeast Asia during the rainy season. 4. As the historical background, Cox. B4 and Cox. B5 have been commonly isolated during an active surveillance on enteroviruses conducted in Aichi Prefecture. However, echo 1 has been rarely and echo 29 has never been isolated in the 21 year period of the study. 5. Serologically, antibody prevalence rate was very low to echo 1 and 29 in Aichi Prefecture, which suggests that the spread of these viruses has not occurred and the inhabitants are easily infected during their stay in the prevalent countries. The careful investigation on the importation of such enteroviruses seems necessary.
