In recent years, hospital infection problem is drawing a social attention. About the indoor air environment in a hospital, although several reports on the indoor airborne microbes in large hospitals have been published, and the actual status of airborne microbial concentration is reported in detail, there are few papers on the behavior of airborne microbes in small hospitals which are numerically more than the large hospitals. This paper reports the results obtained by 1-year field measurements in a small hospital located in Aichi province, Japan. The main conclusions are as follows. (1) The indoor airborne microbe concentration in the survey hospital, where natural ventilation system was adopted, shows the variations on the changes of indoor air temperature and relative humidity through one year. (2) Since the airborne bacteria concentrations in the waiting room and the consulting room were almost the same concentration through the year, the possibility of cross contamination was suggested. (3) From the viewpoint of removal of the airborne microbes, it is desirable to install an air cleaning device in the survey hospital.
