Understanding the aerosol transmission mechanism of respiratory infectious diseases is crucial for predicting indoor air circulation and optimizing ventilation system design. A literature search was conducted using various keyword combinations in PubMed database. The selection included studies examining impact microclimate parameters performance on risk viral transmission. Since 2020, there has been increasing interest studying how infections spread via aerosols within buildings transportation infrastructure, considering operational conditions engineering systems. Currently, substantial evidence supports dependence viability temperature humidity levels. Maintaining an optimal relative 40–60% at standard room essential not only stability but also virus neutralization. However, a lack investigating effects mobility pollution pathogens. significant body confirms influence efficiency infection buildings. To reduce viruses, exchange rate least 30 m3/h per person recommended. Based findings, set practical recommendations operation amidst increased disease incidence developed. Discrepancies between international Russian regulatory requirements regarding climate quality standards have identified, emphasizing need improved measures to mitigate infections.

Background/Objectives: This study aimed to evaluate the prevalence of viral agents identified by Multiplex PCR in acute respiratory infection (ARVI) patients at Edirne Sultan 1, Murat State Hospital, from April 2023 2024, and investigate relationship between monthly average humidity positivity rates. Methods: The included 764 adult (aged 18 older) diagnosed with influenza symptoms. Respiratory samples were collected analyzed for COVID-19, A B, RSV using PCR, results evaluated retrospectively. Continuous variables compared a t-test, categorical chi-square test. logistic regression analysis was performed COVID-19. In this analysis, dependent variable, while age, gender, level served as independent variables. Results: COVID-19 detected 142 (18.6%), INF-A (influenza A) 13 (3.7%), INF-B B) 15 (4.2%), 2 (0.6%). Higher (over 60%) associated reduced rates low (up 40%)/normal (40-60%) correlated rate (p < 0.05 both). Logistic indicated that high levels offer protection against (OR: 0.356; 95% CI: 0.245-0.518). Conclusions: Our provides essential epidemiological data summarizing virus distribution Edirne.

Odor guide values (OGV) are used when a person is exposed to an odor in room and complains about annoyance. OGV derived from detection thresholds (ODT) measured under standard environmental conditions. The study question was whether uncomfortable conditions alter perception should therefore be considered applying OGV. ODT for n-butanol were determined with olfactometer air. Twenty healthy, non-smoking volunteers (10 women/10 men, 19–50 years) selected trained compliant the European Standard Olfactometry EN 13725:2022. average temperature between 22 °C 23 °C, warm light (2800 Kelvin), quiet fan noise (45 dB), 415 ppm carbon dioxide (CO2), relative humidity 34 % 42 %.
