Background and objective:The presence of biological aerosols in the air of medical centers is more than other enclosed spaces. Determining the role and importance of such factors always attracted the attention of health and medical researchers. This study aimed to evaluate the bacterial density of surgical and infectious wards in two important hospitals in Kermanshah and environmental factors affecting them.

Methods: In this study, a total of 160 samples were taken. 128 samples related to the air of surgical and infectious wards in two stages, before and after disinfection of wards and 32 samples related to the hospital outside air were selected as the control sample. MCS Flite (SKC) air sampling pump was equipped with a Biostage 225 (SKC) microbial sampling cassette made in America. Data were analyzed by using SPSS 19.

Results: The highest density of bacteria in the air was measured in Imam Khomeini hospital (402.7± 200.3 CFU/m3) and lowest in Imam Reza hospital (258.6 ± 90.5 CFU/m3). The relation between air temperature and density of all bacteria was significant inverse and the relation between all population and bacterial density was significant and direct.

Conclusion: It seems that reduced bacterial density in wards’ air occurs by increasing the air temperature due to increasing air size and replacing air in wards. Presence of population in wards plays an important role in increasing the bacterial density.
