Background: Acute Respiratory Infections (ARIs) are a major cause of morbidity and mortality among children under five years, especially in low- and middle-income countries such as Nigeria. Effective household management by caregivers plays a crucial role in early recognition, prompt treatment, and prevention of complications. However, inadequate knowledge, poor health-seeking behaviour, and inappropriate treatment practices remain significant challenges. Aim: To assess the household management of ARI symptoms among caregivers of under-five children in Egor Local Government Area, Benin City, and identify factors influencing management practices and treatment outcomes. Methods: A community-based descriptive cross-sectional study was conducted among 506 caregivers selected using a multistage sampling technique. Data were collected using structured interviewer-administered questionnaires adapted from standard survey tools. Information obtained included socio-demographic characteristics, knowledge of ARIs, prevalence of symptoms, care-seeking behaviour, factors influencing management, and treatment outcomes. Data were analysed using IBM SPSS version 27.0. Descriptive statistics and Chi-square tests were used to determine associations, with statistical significance set at p < 0.05. Results: The mean age of caregivers was 35.98 ± 11.04 years, with the majority being mothers (73.9%) and females (76.7%). Most respondents (80.2%) had heard of ARI. Knowledge of danger signs (94.3%) and prevention (74.6%) was generally good, while knowledge of symptoms (29.3%) and causes (30.3%) was poor. The prevalence of ARI in the last two weeks was 14.8%. A majority of caregivers (70.7%) sought treatment, mainly from primary health centres and government hospitals (26.4% each). However, only 35.8% sought care on the same day. Major barriers to care-seeking included cost (31.8%) and perceived non-severity of illness (27.3%). Most children (77.3%) had complete recovery, with few complications (2.7%) and low hospitalization rates (5.3%). Caregiver age (p = 0.009) and sex of the child (p = 0.037) were significantly associated with treatment outcomes. Conclusion: Although caregivers demonstrated good knowledge of ARI prevention and danger signs, significant gaps exist in knowledge of symptoms and causes. While care- seeking behaviour was relatively high, delays and inappropriate practices persist. Strengthening caregiver education, improving access to affordable healthcare, and addressing socio-economic barriers are essential to improve ARI management and reduce childhood morbidity and mortality.

This study investigated the occupational health risks at an airport, focusing on air pollutant concentrations, their spatiotemporal variation, and the associated respiratory health effects among airport workers (N=129). Air quality monitoring was conducted in four areas (Runway, Parking Lot, Departure area, and Reception) during the morning and afternoon periods for carbon dioxide (CO2 ), coarse particulate matter (PM10 ), and fine particulate matter (PM2.5 ). The data were analysed via ANOVA and paired samples t tests. A survey collected data on workers' sociodemographic, workrelated risks, and self-reported respiratory symptoms. Environmental monitoring identified PM2.5 as the primary air quality hazard. The highest observed mean PM2.5 concentration (24.1 μg/m3) exceeded the strict WHO 24-hour guideline. Statistical analysis confirmed significant spatial variation in PM2.5, with the Runway and Parking Lot acting as hotspots and a highly significant temporal spike in the afternoon (p=0.001). Coughing was the most prevalent reported symptom (57.4% of workers). Chi-square tests revealed a strong correlation between respiratory symptoms (cough, phlegm, shortness of breath, and chest pain) and both smoking and a family history of chronic respiratory issues (p≤0.007 for all). Furthermore, workers demonstrated critical systemic failure in safety protocols, with 83.7% lacking knowledge of the proper use of personal protective equipment (PPE) and 96.9% unaware of routine air quality monitoring. The airport environment presents a substantial and avoidable health risk driven by noncompliant PM2.5 levels and systemic safety management failures. Recommendations include implementing mandatory, hands-on PPE training, establishing a transparent PM2.5 monitoring system in hotspots, and creating an occupational health program to screen and counsel high-risk
