摘要

新冠肺炎是一种以发热、咳嗽、上气不接下气为主要症状的急性呼吸道疾病。世卫组织报告,截至2020年6月21日,全球共确诊病例8708008例,死亡461715例(病死率5.3%)。印度尼西亚确诊45,891例,死亡2,465例(病死率37%)。最危险的人是与covid - 19患者有身体密切接触的人,包括卫生工作者。本研究的目的是了解covid - 19大流行前和期间医院患者的微生物室内空气质量。方法:本研究采用观察性横断面研究设计。该研究于2019年12月至2020年6月在东爪哇的一家医院进行。本研究的样本是某医院病房的空气。研究变量为新冠肺炎患者病房的微生物数量、温度和湿度,每个房间测量3个不同的测量点。结果与讨论:结果表明,疫情前空气中微生物数量平均约为46.31 CFU/m3,平均温度为27.64℃,湿度为44.58%;疫情发生后空气中微生物数量增加至64 CFU/m3,平均温度为27.77℃,湿度约为42.46%。经统计分析,疫情前与疫情中病区微生物数量差异有统计学意义(p值为0.00)。结论:结果表明,疫情前和疫情中微生物数量有所增加,但仍未达到质量标准。新冠肺炎患者的增加可能是室内空气微生物数量增加的原因。建议医院要求通过调节通风来控制治疗室的空气质量。

Microbiology Indoor Air Quality at Hospital During the Covid19 Pandemic
Introduction: Covid19 was an acute respiratory disease with fever, cough, and out of breath as the symptoms. WHO reported that until June 21st 2020, there were 8,708,008 cases were confirmed with 461,715 number of death (CFR 5.3%). In Indonesia, there were 45,891 cases were confirmed with 2,465 number of death (CFR 37%). People who were most at risk were people who physically close contact with the Covid19 patient, including health workers. The purpose of this study was to know the microbiology indoor air quality of Covid19 patient at Hospital before and during the pandemic. Method: The study design of this research was observational cross sectional. The study was done at a Hospital in East Java on December 2019 – June 2020. The sample of this research was a ward’s air in a Hospital. The research variable was the number of microbiology, temperature, and humidity of the ward of Covid19 patient that was measured 3 different points of measurement each rooms. Result and Discussion: The result showed that the average of the number of microbiology before the pandemic was about 46.31 CFU/m3 with the average of the temperature was 27.64°C and the humidity was 44.58%, while during the pandemic the number of microbiology in the air increased to 64 CFU/m3 with the average of the temperature was 27.77°C and the humidity was about 42.46%. Based on the statistic analysis, there were differences between the numbers of the microbiology before and during the pandemic in the ward of Covid19 patients (p value 0.00). Conclusion: The result showed that the number of the microbiology was increased before and during the pandemic although it was still under the quality standard. Increasing of Covid19 patient was the probably reason of the increasing the number of the indoor air microbiology. It was recommended the hospital requires to control the air quality of the treatment room by regulating air ventilation.
