“…9 Previous studies of air quality primarily focused on intensive care units, 4,7,10,11 operating rooms, 12,13 negative-pressure patient isolation rooms, 6,9 and public areas in hospitals. 3,[14][15][16][17][18][19] However, few studies assessed viral contamination in the patients' rooms in a given hospital ward.…”

Few studies have assessed viral contamination in the rooms of hospital wards. This cross-sectional study evaluated the air and objects in patient-occupied rooms in pediatric wards for the presence of common respiratory viruses and Mycoplasma pneumoniae.Air samplers were placed at a short (60–80 cm) and long (320 cm) distance from the head of the beds of 58 pediatric patients, who were subsequently confirmed to be infected with enterovirus (n = 17), respiratory syncytial virus (RSV) (n = 13), influenza A virus (n = 13), adenovirus (n = 9), or M pneumoniae (n = 6). Swab samples were collected from the surfaces of 5 different types of objects in the patients’ rooms. All air and swab samples were analyzed via real-time quantitative polymerase chain reaction assay for the presence of the above pathogens.All pathogens except enterovirus were detected in the air, on the objects, or in both locations in the patients’ rooms. The detection rates of influenza A virus, adenovirus, and M pneumoniae for the long distance air sampling were 15%, 67%, and 17%, respectively. Both adenovirus and M pneumoniae were detected at very high rates, with high concentrations, on all sampled objects.The respiratory pathogens RSV, influenza A virus, adenovirus, and M pneumoniae were detected in the air and/or on the objects in the pediatric ward rooms. Appropriate infection control measures should be strictly implemented when caring for such patients.

“…IAQ hot-spot locations were screened at each public site through walk-through detection in the first stage, and the measurements of indoor air pollutants were continuously monitored for 24 hour or sampled for lab analysis according to Taiwan EPA standard methods [3]. The detailed procedures of IAQ investigation can be referred to Wang et al [4], and the employed measurement methods and utilized detection apparatus or instruments were summarized in Kung et al [5]. IAQ measurements include CO 2 , CO, HCHO, TVOCs, bacteria, fungi, PM 10 , PM 2.5 , O 3 and temperature, which were conducted during year 2010 and 2011.…”

The selected 21 public sites for indoor air quality (IAQ) investigation located at Penghu and Kinmen Islands (Taiwan). IAQ measurements include CO2, CO, HCHO, TVOCs, bacteria, fungi, PM10, PM2.5, O3 and temperature, which were conducted during year 2010 and 2011. The results showed that the concentrations of CO, HCHO, PM10 and PM2.5 were below Taiwan EPA’s suggested IAQ threshold levels at all public sites. CO2 concentrations at hospitals and school are all exceeding category 1 threshold of 600 ppm. Besides, the levels of O3 and bacteria for hospitals and fungi for schools were all higher than the suggested IAQ threshold levels. One supermarket was found exceeding the suggested IAQ threshold levels on TVOCs and CO2. The theater was found exceeding the suggested bacteria threshold. This study discovered that the high CO2, bacteria and fungi levels occurred at various public sites. Accordingly, the regulated strategy of crowd control and air conditioning management was required for a healthy indoor environment.

Abstract Indoor air quality in hospitals has been specifically considered in terms of its impact on health. Air quality is an important risk factor influencing the health of staff and patients who are in contact with indoor air inhaled in hospitals. Over the past two decades, hundreds of studies have been developed to assess pollution in hospital environment. Two hundred and fitfy papers from around the world, from the last two decades, were identified and reviewed. Recent studies have found that the presence of various chemical and biological pollutants affected the health of patients, staff and visitors. Nearly all the reports agree that chemical and biological pollutants in the hospital environment have adverse effects. In most of the reviewed papers, analysis of health hazards was conducted for personnel and patients to toxic metals, chlorine, fine (PM2.5) and coarse (PM2.5−10) particles, and bio-aerosol in the inhaled air of the hospital environment. Some papers showed that some of the metals are carcinogens and others do not have a carcinogenic risk. Bio-aerosols as a biological pollutant are usually defined as airborne bacteria, fungi, viruses, pollen and their by products. These biological pollutants are associated with a wide range of health effects in hospital environments. This review can serve as an introduction and as the statement of the problem for more original research in this regard.
