Abstract

Background: Bacterial indoor air load refers to the level of bacteria within and around dwellings and other structures. Pathogens, bacterial cell fragments, and bacterial organisms' byproducts can all pose major issues indoors, especially in prison inmate cells. However, there is lack of data on bacterial load and contributing factors in the East Hararghe zone and Harari regional state. The lack of studies on microbiological indoor air quality in prisons with contributing factors will therefore be filled by this investigation.

Objectives: The study aimed to assess bacterial indoor air load and contributing factors in prison inmate cells from October 1 to October 30, 2020.

Methodology: An institutional cross-sectional study was employed. All of the prisons in the East Hararghe zone and the Harari regional state served as the study's and source population. 62 prison cells were used in the investigation. Samples were obtained using the passively settling plate technique. The data were evaluated through the use of SPSS statistical software, Excel, and the statistical procedures of ANOVA, correlation, and chi-square test.

Results: The maximum and minimum bacterial loads, were recorded at 8:00 am (3027 CFU/m3) and 2:00 pm (1048 (CFU/m3) respectively. The correlation between the temperature and bacterial load was strongly positive (r = 0.680, p = 0.047), and the correlation of the moisture content and bacterial load was strongly negative (r = -0.671, p = 0.039).

Conclusion: The levels of bacteria were higher than the guideline (2000 CFU/m3). While the relative humidity of indoor air was negatively correlated with bacterial load, temperature and bacterial load were significantly positively correlated. Harari regional state and East Hararghe zone prison commissions should be alarmed to alleviate these problems. The building standards need to be completely updated to the latest standards.

埃塞俄比亚东部东哈拉尔盖区和哈拉里地区州监狱囚犯牢房的室内空气细菌质量及相关因素。

背景：室内空气中的细菌量指的是住宅和其他建筑内部和周围的细菌含量。病原体、细菌细胞碎片和细菌有机体的副产品都会在室内造成严重问题，尤其是在监狱的囚犯牢房中。然而，东哈拉盖地区和哈拉里州缺乏有关细菌负荷和致病因素的数据。因此，本次调查将填补对监狱室内空气质量中微生物及诱发因素研究的空白：本研究旨在评估 2020 年 10 月 1 日至 10 月 30 日期间监狱囚犯牢房的室内空气细菌负荷和诱因：方法：采用机构横断面研究。东哈拉盖区和哈拉里地区州的所有监狱都是研究对象和来源人群。调查中使用了 62 间牢房。采用被动沉降板技术采集样本。使用 SPSS 统计软件、Excel 和方差分析、相关性和卡方检验等统计程序对数据进行了评估：最高和最低细菌量分别出现在上午 8:00 时（3027 CFU/m3）和下午 2:00 时（1048 CFU/m3）。温度与细菌量之间呈强正相关（r = 0.680，p = 0.047），水分含量与细菌量之间呈强负相关（r = -0.671，p = 0.039）：结论：细菌含量高于指导标准（2000 CFU/m3）。室内空气相对湿度与细菌量呈负相关，而温度与细菌量呈显著正相关。哈拉里地区州和东哈拉盖区监狱委员会应引起警觉，以缓解这些问题。建筑标准需要完全更新为最新标准。
