Poor indoor air quality is one of the most important factor causing occupational health problems such as sick building syndrome (SBS). Most previous research on risk factors of SBS is evaluated in the office or school environments rather than in the hospital. The aim of this study is to investigate the prevalence of SBS and its related effect on hospital workers in poorly-ventilated and confined working environments through a set of the questionnaires completed from March to June of 2017. The relationship between SBS-Related symptoms, individual characteristics, work environment and conditions were analyzed using Poisson regression. The prevalence of sick building syndrome was 70.1%. The most common symptoms reported by hospital workers include fatigue, headache, and feeling heavy-headed. There was a significant relationship between the prevalence of syndrome and sex, overload of work, atopy as well as varying room temperature.

Staphylococcus aureus (S. aureus) has long been recognized as an important human pathogen causing many severe diseases. It is also a part of human normal flora with its ecological niche in the human anterior nares. This study focused on screening S. aureus nasal carriage in community and its relationship to human physiological and pathological factors which have not been studied in Vietnam previously. Two hundred and five volunteers in Ho Chi Minh City from 18 to 35 and over 59 years old both male and female participated in the study. Result showed that the prevalence of S. aureus nasal carriage in southern Vietnamese community was relatively low, only 11.2% (23/205), much lower than that in other international reports on human S. aureus. In addition, nasal carriage of the older age group (> 59 years old, 13.7%) was higher than that of younger age (18-35 years old, 10.4%). Other potential risk factors such as gender, career, height, weight, history of antibiotic usage, daily nasal wash, use of nasal medication sprays, acne problems, smoking and nasal problems showed no significant impact on S. aureus carriage. The obtained S. aureus nasal isolates were all sensitive to vancomycin. Lincomycin and tetracycline had low resistance rate with 4.3 % and 17.4 %, respectively. However, the isolates showed particularly high rate of multidrug resistance (54.2%) In summary, our data provided researchers an overview on S. aureus nasal carriage and antibiotic susceptibility profile of the community- isolated S. aureus in Vietnam. This would serve as valuable information on assessing risk of community-acquired S. aureus infections.
