Microorganism pollutants can be bacteria, fungi and spores in the room. Microorganisms that are distributed in space are known as bioaerosols. The spread of bioaerosol in hospitals can result in danger to human health, especially for patients with weakened immune systems. Risk assessment is very important for an organization or institution to overcome current and future risks related to contamination. The QMRA approach has been applied to inform standards for the microbiological quality of food, water, air, and touched surfaces. The method uses descriptive analytics with a literature review design. Data was obtained through searches on the electronic databases Pubmed , Elsevier , and Google Scholar. Keyword terms such as: (Bioaerosol * and Airborne * and Infections * and Hospital *) , ( Bioaerosol * and Microorganisms * and Inhalation ) , ( Airborne * and Microbial and * Hospital * or Intensive Room *) , ( Bioaerosol * Quantitative Microbial Risk Assessment (QMRA)* and Hospital-Acquired Infection* and Intensive Care unit ) . health risks AND sensitivity AND aerosol pollution AND microorganisms OR fungi OR bacteria AND montercarlo AND intensive care OR hospital rooms: (Bioaerosol * and Airborne * and Infections * and Hospital *) , ( Bioaerosol * and Microorganisms * and Inhalation ) , ( Airborne * and Microbial and * Hospital * or Intensive Room *) , (Bioaerosol * Quantitative Microbial Risk Assessment (QMRA) * and Hospital-Acquired Infection * and Intensive Care unit ) . health risks AND sensitivity AND aerosol pollution AND microorganisms OR fungi OR bacteria AND monter carlo AND intensive care OR hospital rooms are used. The search covered research conducted over the past ten years, from 2012 to 2022. Of the 27 articles found using the search terms, seventeen articles were selected for examination. The four categories of analysis are population, type of study, aims, and findings. According to research, one of the parameters for evaluating indoor environmental quality is bioaerosol. Microbial bioaerosol media in the air are ambient air and indoor air. The routes of exposure can be through ingestion/swallowing, direct contact and inhalation/inhalation. The cause of hospital infections is because hospital environmental conditions do not meet the requirements, causing high levels of room air germs. Poor hospital indoor air quality can cause HAIs. Therefore increasing levels of mechanical or natural ventilation as well as regular cleaning and maintenance activities can play an important role in improving indoor air quality.

Background: Valeriana officinalis is most commonly used as traditional medicine. Valerenic acid is the primary component of Valerian officinalis which inhibits the catabolism of enzyme induced breakdown of gamma amino butyric acid (GABA) in the brain, resulting in sedation. The aim of this study is to determine the level of GABRB3 protein, as part of major inhibitory neurotransmitter in the brain, after administration of Valerian extracts in BALB/c mice. Materials and Methods: This is an experimental study using animal model with post test-only controlled group design. Twenty healthy adult male BALB/c mice were randomly divided into four groups, negative control group (Aquadest), positive control group (Diazepam 0.025 mg/10 g), first treatment group (Valerian extract 2.5 mg/10 g) and second treatment group (Valerian extract 5 mg/10 g). The drugs were administered via gastric gavage for seven consecutive days. The blood was drawn from each mice on the first day (before treatment) and on the seventh day of experiment (2 hours after treatment). The blood sample was examined by enzyme-linked immunosorbent assay (ELISA) to determine the GABRB3 protein level. Results: GABRB3 protein level in BALB/c mice after administration of Valerian extract was increased significantly in both treatment group (p \<0.0001). The highest increment in protein levels was found in the first treatment group with an increase of 2.988 μmol/L, compared with the second treatment group with an increase of 2.146 μmol/L. Conclusion: GABRB3 protein level in BALB/c mice were increased after administration of Valerian extract. Administration of higher dose does not yield in higher GABRB3 protein level nor sedative effect.
