BACKGROUND: Hospital sanitation workers (SWs) are exposed to numerous occupational hazards due to workplace conditions such as unsafe and unhygienic working environment in the hospitals. Therefore, knowing magnitude, types and source of occupational hazard exposures with their determinants are very significant for further mitigations.
METHODS: Hospital based cross-sectional study design was conducted in public hospitals, eastern Ethiopia from 1st May to August 30th, 2023. 809 SWs participated. Data was entered into Epi Data Version 3.1 and Stata 17MP version used for analysis. Descriptive analysis was applied to describe the data. While, multilevel logistic regression was explored to determine the association between outcome and independents among at individual level (model 1), at hospitals (model 2) and combination of the two (model 3). The crude odds ratio (COR) and adjusted odds ratio (AOR) for models 2 and 3 were reported. Variables with an AOR with a 95% confidence interval (CI) at a p-value < 0.05 were reported.
RESULTS: Out of 809 SWs, 729 (90.11%) responded. The overall magnitude of self-reported occupational hazard exposures among SWs was 63.65% (95% CI 0.60-0.67). Of this, biological, chemical, and ergonomic hazards accounted for 82.44%, 74.76%, and 70.92%, respectively. The multilevel logistic regression shows that having social recognition (AOR: 0.37, 95% CI 0.14, 0.91), neutral attitude (AOR: 0.48, 95% CI 0.17, 1.41) as compared to negative attitude. The model also found that SWs those supervised could reduce the likelihood of occupational hazard exposures by 50% times (AOR: 0.50, 95% CI 0.18, 1.38) as compared to non-supervised SWs. The final model predicted the variation of occupational hazard exposures among sanitary workers from the hospitals to hospitals was 26.59%.
CONCLUSIONS: The concluded that hospital sanitary workers are facing biological, chemical, ergonomic, physical, psychological, mechanical, and electrical hazards. This study\'s findings predicted that dissatisfied with their environment, working more than 8 hr per a day,  a negative attitude towards workplace risks and inadequate supervision may serve as contributing factors for the likelihood of occupational hazard exposures among these groups. Thus, the study suggested that hospitals could reduce these hazard risks if they implement the Risk Assessment and Safety Management (RASM) model, which includes multi-modal strategies, indicators and tripartite philosophy.

Sanitary workers are exposed to a variety of occupational hazards in a variety of working environments, which can result in occupational-related outcomes. As a result, the goal of this review was to identify occupational health and safety outcomes among sanitary workers worldwide.
PRISMA was used as flow diagram and PICOS was used review questions. The studies published in English were searched from databases and others methods ranging from 2000 to 2022. Boolean logic (AND, OR), MeSH, and keywords used: (Occupation *OR Job *OR Work) AND (Occupational related respiratory Symptoms *OR Disease) AND [Solid waste collectors (SWCs) *OR Street sweepers (SS) *OR Sewage workers and waste treatment (STWs)] AND (Countries).
A total of 228 studies were identified from 23 countries across the world. Studies were found via PubMed (n = 40), Medline (n = 25), Embase (n = 11) and Global Health (n = 66) and Google scholar (n = 63) and from previous (n = 23). From 8,962 of eligible sanitary workers, about 4,742 (54%), 1714 (19%) and 1,441 (16%) were sewage, sweepers and solid waste workers, respectively. A total study (n = 51) were eligible for occupational health and safety outcomes. Of these, respiratory problems accounted 27 (52%) and Gastroenteritis 14 (27%).
Despite a large number of studies to date provides sanitary employees all over the world face occupational-related risks, hence more research is needed to enhance and quantify illness burden among sanitary workers.

Objectives. Sanitary workers are more likely to experience musculoskeletal disorders (MSDs) due to a lack of ergonomics principles and poor job design. Thus, this systematic review and meta-analysis aimed to quantify MSDs among sanitary workers. Methods. The PRISMA and PICOS protocols were used for flow diagrams and review questions, respectively. Articles published between 2000 and 2022 were eligible. The keywords \'(Musculoskeletal Disorders) AND (Solid waste collectors *OR Street sweepers *OR Sewage workers *OR health facilities cleaners)\' and MeSH terms were utilized. The data were analyzed using STATA version 17 with a 95% confidence interval (CI). Results. A total of 158 papers were qualified, with 26 studies from 17 countries and a total of 6586 sanitary workers. The global prevalence of MSDs among sanitation workers was 40.52% (95% CI [32.47, 48.67]; p < 0.05). It was 43.32% (95% CI [31.98, 54.68]; p < 0.05) in high-income countries and 38.58% (95% CI [26.94, 50.18]; p < 0.05) in low-income countries. By subgroup analysis, it was 45.12% (95% CI [32.57, 57.67]; p < 0.05) for solid waste collectors, which is the highest prevalence among other workers. Conclusion. Current evidence shows that sanitation workers have a higher prevalence of occupationally associated MSDs, which might be lowered by using ergonomic work design principles.

BACKGROUND: Sanitation or sanitary workers are exposed to hepatitis virus infections because of filthy and dangerous working conditions. The current global systematic review and meta-analysis aimed to estimate the pooled sero-prevalence of occupationally associated hepatitis virus infection among them.
METHODS: Preferred Reporting Items for Systematic Reviews (PRISMA), and Population, Intervention, Comparison, Outcome and study design (PICOS) were used for flow diagram, and review questions, respectively. Four databases other methods were used published articles from 2000 to 2022. Boolean logic (AND, OR), MeSH, and keywords were used: (Occupation *OR Job *OR Work) AND (Hepatitis A *OR Hepatitis B virus *OR Hepatitis C virus *OR Hepatitis E virus) AND (Solid waste collectors [SWCs] *OR Street sweepers [SS] *OR Sewage workers [STWs] *OR health care facilities cleaners [HCFCs)) AND (Countries). Stata MP/17 software was used for pooled prevalence analysis, meta-regression analysis (Hedges) at a 95% confidence interval (CI:95%).
RESULTS: A total of 182 studies were identified studies, a total of 28 studies were included from twelve countries. Of these, from developed (n = 7) and developing countries (n = 5). From total a of 9049 sanitary workers, 5951(66%), 2280 (25%) and 818 (9%) were STWs, SWCs and SS, respectively. Globally, the pooled sero-prevalence of occupational-related hepatitis viral infections among sanitary workers was 38.06% (95% CI: 30-0.46.12). Of this, it was 42.96% (95% CI: 32.63-53.29) and 29.81% (95% CI: 17.59-42.02) for high-income and low-income countries, respectively. Meanwhile, by sub-analysis, the highest pooled sero-prevalence of hepatitis viral infections by categories, type and year were 47.66% (95%CI: 37.42-57.90), 48.45% (95% CI: 37.95-58.96), and 48.30% (95% CI: 36.13-60.47) for SWTs, HAV, and 2000 to 2010 year, respectively.
CONCLUSIONS: The consistency of the evidence suggests that sanitation workers, particularly sewage workers, are susceptible to occupationally acquired hepatitis regardless of their working conditions, necessitating significant changes to occupational health and safety regulations from governmental policies and other initiatives to reduce risks among sanitary workers.

UNASSIGNED: Healthcare facilities produce a variety of trash that, if handled improperly, could endanger the environment, the health of patients and clients, healthcare personnel, and the general public. Health staff have been given training on infection control and healthcare waste management. It is not apparent whether similar initiatives are taken for sanitary personnel, though. By evaluating sanitary workers\' knowledge, attitudes, and practices about healthcare waste treatment in the Dodoma region of Tanzania, this study sought to clarify the situation.
UNASSIGNED: From March to August 2022 in Dodoma, Tanzania, a descriptive cross-sectional study using a quantitative methodology was conducted on 156 randomly chosen sanitary workers. The primary data collection instruments were structured questionnaires that were conducted by interviewers and a trash checklist that the research team created. Statistical Package for Social Sciences computer software was used to conduct a descriptive analysis of the data with a 95% confidence level and a 5% level of significance.
UNASSIGNED: The average age was 28 ± 6.2 years, and there were 74.4% females. Of all of the health institutions under study, 78.4% of the generated medical waste was non-infectious, whereas 21.6% of it was infectious. The share of non-infectious and infectious healthcare waste created by regional referral hospitals was 43.5% and 13.2%, respectively. While 67.8% of sanitary workers believed that handling healthcare waste was not their problem and 63.6% of sanitary workers actually displayed subpar practices of handling healthcare waste, 74.4% of sanitary workers had low understanding about handling healthcare waste. Their procedures for handling medical waste were substantially influenced by the kind of healthcare facility, sex, education, job experience, knowledge, and attitude (p < 0.05).
UNASSIGNED: Sanitary staff members had limited understanding and thought they were less concerned with gathering, moving, and storing medical waste. To provide the highest level of health safety, national health policy and facility-based interventions must support and fund participatory waste management training that is tailored to the sociodemographic profiles of sanitary employees.

UNASSIGNED: To find out the impact of occupational and socio-demographic factors on the health related quality of life of sewerage and sanitary workers in Karachi.
UNASSIGNED: A cross-sectional study was conducted during 2019. Four hundred workers were chosen from five districts of Karachi using a non-probability convenient sampling technique. An Urdu version of WHO BRIEF quality of life questionnaire was used to collect the data about workers general health status and quality of life. Descriptive analysis was done and Chi-square test was used for the association of socio-demographic factors and quality of life. Multiple regression model was used to predict QOL of all domains. P-value<0.05 was considered as statistically significant.
UNASSIGNED: Out of 400 sanitary workers, 228 (57.0%) were sweepers and the rest 172 (43.0) were sewerage workers. The majority of the workers 321 (80.3%) were male and 246 (61.5%) were illiterate. The vast majority of the workers 386 (96.5%) were not immunized against typhoid, / hepatitis and tetanus. Ninety-one percent (91%) were not using any kind of safety gadgets while at work. Male workers, married workers of both sexes and those with some education had a little better quality of life than their counterparts. Sanitary employees likewise had a higher quality of life score than sewage workers (P-value<0.05).
UNASSIGNED: The majority of workers, particularly sewage workers, have a very poor quality of life. Along with very bad working circumstances, their standard of living is significantly below par. They were not given any safety equipment. They were handling untreated sewage/waste with their bare hands, and they have never received a typhoid/hepatitis /tetanus vaccine.

BACKGROUND: The production of waste is due to the result of commercial activities, consumption, and utilization of products or materials. It is further believed that mainly solid waste includes non-harmful waste which may be from households, mainly kitchens, and even from organizations and institutions, shops and various types of markets, and manufacturing industries. Solid waste handling, management, and accurate and appropriate disposal is a hot topic relating to public and environmental health concerns.
METHODS: A cross-sectional quantitative study design was incorporated to assess knowledge, attitude, and practice and associated factors regarding prevention of occupational risks and health hazards among sanitary workers in Bulehora University, a government organization in West Guji Zone, Ethiopia. One hundred and ninety-one solid waste handlers found to be working in this institution were included in the study.
RESULTS: The response rate of samples in the present study was found to be 94.4%, of which the majority were females, which accounted for 79.7%. The median age of the study samples was 29 years. It was found that 64% of study samples stated good knowledge of the prevention of occupational health risks. About 76.4% of solid waste collectors had a good attitude and only 8.9% showed good practice regarding prevention of occupational health hazards. Job dissatisfaction was found to be a statistically significant factor along with the use of personal protective equipment (PPE) in implementing good practice work patterns among sanitation workers, even though they had been provided with basic personal protective equipment.
CONCLUSIONS: The study concluded that there is a need for development of plans on implementation of basic occupational health services while enforcing the provision of personal protective equipment and supervising solid waste collectors.

Bartonella spp. are increasingly implicated in association with a spectrum of zoonotic infectious diseases. One hundred sanitary workers in La Rioja, Spain completed a questionnaire and provided blood specimens for Bartonella spp. serology and Bartonella alpha-Proteobacteria growth medium (BAPGM) enrichment blood culture/PCR. Six immunofluorescence assays (IFA) were performed and aseptically obtained blood specimens were inoculated into liquid BAPGM and subcultured onto blood agar plates. Bartonella DNA was amplified using conventional and real-time PCR assays. The Bartonella spp., strain, or genotype was determined by DNA sequencing. Bartonella seroreactivity was documented in 83.1% and bloodstream infection in 21.6% of participants. Bartonella henselae, B. vinsonii subsp. berkhoffii genotypes I and III, and B. quintana were identified. IFA seroreactivity and PCR positivity were not statistically associated with self-reported symptoms. Our results suggest that exposure to and non-clinical infection with Bartonella spp. may occur more often than previously suspected in the La Rioja region.

Objective. This study was conducted to assess hazards faced by elementary workers. Methods. A questionnaire survey and a respiratory function test (spirometry) were carried out on 150 respondents. Results. Major hazards identified related to sharp objects, heavy weight lifting, thermally harsh conditions, working at height, whole body vibration, chemicals, pathogens, increased noise levels and confined space entry. Workers suffered from upper and lower respiratory disorder symptoms, digestive problems, optical and musculoskeletal issues, etc. Spirometric measurement showed obstructive lung disorders to be highest among construction workers (CW) (48%) followed by sanitation workers (SW) (32%) and solid waste pickers (SWP) (28%). Restrictive lung pattern was dominant among SW (56%) followed by SWP (46%) and CW (42%). The observed FEV1/FVC in diseased SWP, SW and CW ranged from 51 to 96%, from 52 to 98% and from 31 to 99% respectively while observed mean FEV1 was 2.15, 1.79 and 1.70 L, respectively. Conclusion. The study findings show that occupational exposure can significantly influence respiratory system impairment and contribute to other ailments among elementary workers. The study recommends use of appropriate protective equipment and regular medical examination for early recognition of any health risk so that timely interventions for effective management may be undertaken.

An estimated 1.2 million scavengers in the country are involved in the sanitation of our surroundings. The working conditions of these sanitary workers have remained virtually unchanged for over a century. Apart from the social atrocities that these workers face, they are exposed to certain health problems by virtue of their occupation. These health hazards include exposure to harmful gases such as methane and hydrogen sulfide, cardiovascular degeneration, musculoskeletal disorders like osteoarthritic changes and intervertebral disc herniation, infections like hepatitis, leptospirosis and helicobacter, skin problems, respiratory system problems and altered pulmonary function parameters. This can be prevented through engineering, medical and legislative measures. While the engineering measures will help in protecting against exposures, the medical measures will help in early detection of the effects of these exposures. This can be partly achieved by developing an effective occupational health service for this group of workers. Also, regular awareness programs should be conducted to impart education regarding safer work procedures and use of personal protective devices.
