“…A hospital is a place where employees, patients, visitors, and in some cases students are in contact with microorganisms that could jeopardize their health (4). If health and protective issues are neglected in such places then incidence of infections may be encouraged (5). Based on studies, the most common hospital infections in decreasing order have been reported as; urinary tract infections, infections of surgical scars, pneumonia, bacteremia, and septicemia (5)(6)(7)(8).…”

“…Studies show a significant relationship between level of hospital infection and level of bio-aerosols in the air. Generally, the solid or liquid particles in the air of hospitals contain different types of bacterial, viral and fungal pathogens (5,8). The major pathogens to cause hospital infections include Aspergillus flavus, gram-positive bacilli, Neisseria meningitidis, Serratia marcescens, Staphylococcus aureus, Streptococcus pyogenes, and bacillus tuberculosis and they cause pathogenesis from hospital air through transmission from skin, exhaled air, operation room transmission, surgical instruments, contaminated clothes of patients (10,11).…”

As hospital infections increase dangers of microbial contamination and cause mortality in developed and developing countries, 5%-10% in developed and over 25% in developing countries, it is crucial that the problem is given greater attention (9).…”

Background: Bio-aerosols in the air of hospital wards have an important role in the development of infections. It is important to make quantitative and qualitative estimations of microorganisms in the air of these wards as an index for environmental hygiene applicable to different hospital wards. The aim of the study was to investigate degrees of diversity and density of bio-aerosols in the education hospitals of Kerman city. Methods: This study applied a descriptive-cross-sectional methodology in the second half of 2014 in the education hospitals of Kerman city, with bed capacity of over 300. As many as 200 samples were collected from the air in different wards of each hospital using the standard method of the National Occupational Health and Safety Institute. Following collection, samples were placed in an incubator for 48 hours and then bio-aerosol detections were made for and resulting data reported as colonies/m 3 . Results:Results indicated that maximum and minimum degrees of bacterial density were observed in operation rooms and in the intensive care unit (ICU) of Shafa hospital. Furthermore, comparison showed that the operating room at Afzalipour hospital had the lowest level of fungal contamination, while ICU at Bahonar hospital had the highest level of fungal contamination. The emitted fungi of Aspergillus and Penicillium along with the bacteria, staphylococci and Acinetobacter had greater frequencies. The means of bacterial density and fungal density were not equal across the studied hospitals and significant statistical, difference was observed between means of bacterial and fungal density (P ≤ 0.001). Conclusion: Amounts of bacterial and fungal density were greater than those proposed in the American Industrial Health State Conference in 73.3% of the wards in the educational hospitals of Kerman city sampled in this study. Therefore it is suggested that implementation of some, necessary measures for continuous monitoring, promotion of hygienic disinfection standards, and ventilation systems are taken more seriously by stipulating regulations to control this important issue in the country's hospitals.
