本研究的目的是检查冬季儿科原发性免疫缺陷（PPI）病房和普通儿科病房中胃肠病毒污染的程度，并确定医院感染控制干预措施的变化是否会对儿科病房内的环境污染水平产生影响。从2005年12月15日至2006年3月3日，每周从两个病房的11个地点收集环境拭子，并通过逆转录酶PCR检查是否存在诺如病毒（NoV）、星状病毒和轮状病毒（RV）。在两个病房的拭子中分别检测到17%和19%的病毒。根据Gallimore等人2004年的研究，在PPI病房中，NoV和RV的病毒污染分别从20%降至6%和15%降至10%。I.加利莫尔角泰勒，A. R. Gennery，A. J. Cant，A.加洛韦，M. Iturriza-Gomara和J.J.Gray，J.Clin.Microbiol. 44：395 - 399，2006）。总体而言，清洁方案的变更被认为降低了胃肠病毒的环境污染水平，但由于感染控制程序的故障，污染仍然发生，这表明父母经常光顾但工作人员仅偶尔使用的区域存在污染。
The aims of this study were to examine the extent of gastroenteric virus contamination in a pediatric primary immunodeficiency (PPI) ward and a general pediatric ward over a winter season and to determine whether changes to hospital infection control interventions would have an impact on environmental contamination levels within pediatric units. Environmental swabs were collected weekly from 11 sites in both wards from 15 December 2005 to 3 March 2006 and examined for the presence of norovirus (NoV), astrovirus, and rotavirus (RV) by reverse transcriptase PCR. Viruses were detected in 17% and 19% of swabs from both wards. Virus contamination for NoV and RV decreased from 20% to 6% and 15% to 10% of swabs, respectively, in the PPI ward from the 2004 study by Gallimore et al. (C. I. Gallimore, C. Taylor, A. R. Gennery, A. J. Cant, A. Galloway, M. Iturriza-Gomara, and J. J. Gray, J. Clin. Microbiol. 44: 395-399, 2006). Overall, changes to cleaning protocols were deemed to have reduced the level of environmental contamination with gastroenteric viruses, but contamination still occurred due to a breakdown in infection control procedures indicated by contamination in areas frequented by parents but used only occasionally by staff.
