RESUMO
INTRODUCTION: Climate change may affect human health due to various mechanisms including overexposure to environmental pollution or dispersed particles. Lake Urmia (LU) drying in recent years has turned into a crisis with particle distribution as its main manifest. It is told that this crisis may affect the health of neighbouring residents. In this paper, we elaborate on a research protocol developed to assess the potential health consequences of LU drying (LUD) by investigating the distribution of physical and mental health conditions/disorders among residents of LU's surrounding provinces with different exposure levels to LUD outcomes. METHODS AND ANALYSIS: The target population of this study is the residents of the LU basin from East Azerbaijan and West Azerbaijan provinces of Iran. A total of 803 households and 2783 people are studied in 86 clusters. Cluster sampling is applied. The weighting of the samples is based on a satellite map of the density of suspended particles such that people living in areas with higher risk have a higher chance of selection. Various types of measurements are done in three major groups including self-reported health, clinical interview/examination and paraclinical assays. ETHICS AND DISSEMINATION: In this project, all procedures are in accordance with the ethical standards of the Ethics Committee of Tabriz University of Medical Sciences. Moreover, an informed consent letter is obtained from all participants included in the study. The results from this study will be disseminated in international journals and implemented in the primary care guidelines and national policy documents on managing the potential health consequences of LUD.

Background: Non-communicable diseases are of the major health challenges and the leading cause of death in Iran and at the global level. Moreover, Iran is a disaster-prone country and considering the exacerbation of diabetes and chronic respiratory diseases in natural disasters, its healthcare system is facing challenges. This study was designed to explore challenges in providing healthcare services to patients with diabetes and chronic respiratory diseases during disasters in Iran. Materials and Methods: The conventional content analysis is used in this qualitative study. Participants included 46 patients with diabetes and chronic respiratory diseases, and 36 of stakeholders were experienced and had theoretical knowledge. Participants' selection started by means of purposive sampling and continued to the point of data saturation. Data collection was carried out employing semi-structured interviews. Data analysis was performed using Graneheim and Lundman method. Results: Based on participants' experiences, four major challenges in providing care to patients with diabetes and chronic respiratory diseases during natural disasters include integrated management (with three subcategories: control and supervision, patient data management, volunteer management), physical, psychosocial health (with three subcategories: psychological impacts, exacerbation of signs and symptoms, special patient characteristics), health literacy and the behavior (with three subcategories: risk perception, values and beliefs, education and awareness) and barriers to healthcare delivery (with three subcategories: facilities and human resources, financial and living problems and insurances, accessibilities and geographic access). Conclusion: Developing countermeasures against medical monitoring system shutdown in order to detect medical needs and problems faced by chronic disease patients including those with diabetes and chronic obstructive pulmonary disease (COPD), is essential in preparedness for future disasters. Developing effective solutions may result in improved preparedness and better planning of diabetic and COPD patients for disasters, and potentially promote health outcomes during and after disasters.
RESUMO
OBJECTIVES: The prevalence, types, severity, risk ratings, and common pairs of involved drugs, and the most important potential drug-drug interactions (pDDIs) in coronavirus disease 2019 (-COVID-19) deceased cases were evaluated. MATERIALS AND METHODS: We reviewed the medical records of 157 confirmed COVID-19 deceased cases hospitalized in 27 province-wide hospitals. Patients' demographics and clinical data (including comorbidities, vital signs, length of in-hospital survival, electrocardiograms (ECGs), medications, and lab test results) were extracted. The online Lexi-interact database and Stockley's drug interactions reference were used to detect pDDIs retrospectively. The QTc interval and total Tisdale risk score were also calculated. Descriptive analysis, analysis of variance, Fisher exact test, and multivariate analysis were conducted for data analysis. RESULTS: Of 157 study cases, 63% were male, had a mean age of 68 years, and 55.7% had one or more underlying diseases. All patients had polypharmacy, with 69.2% having ≥ 15 drugs/day. We detected 2,416 pDDIs in patients' records, of which 658 (27.2%) were interactions with COVID drugs. Lopinavir/ritonavir among -COVID drugs and fentanyl among non-COVID drugs were commonly involved in the interactions. pDDIs was significantly higher in the polypharmacy group of ≥ 15 medications (p < 0.001). A majority (83%) had received drug(s) with the QTc prolongation effect, of whom 67% had actual QTc prolongations in their ECGs. The regression analysis showed that by increasing 6.7% in polypharmacy, one day increase in-hospital survival can be expected. Moreover, an increase of 2.3% in white blood cells or 10.5% in serum potassium level decreased in-hospital survival by 1%. CONCLUSION: The findings underscored the importance of careful drug choice, especially in the hectic search for early treatments in pandemics of novel diseases. Close monitoring of patients' drug choice is warranted for reducing pDDIs and their adverse effects in any new disease outbreak.

BACKGROUND: Iran's health care system faces significant challenges in managing the growing burden of non-communicable diseases, and these are exacerbated during the frequent natural disasters. The current study was designed to understand challenges in providing healthcare services to patients with diabetes and chronic respiratory diseases during such crisis periods. METHODS: The conventional content analysis was used in this qualitative study. Participants included 46 patients with diabetes and chronic respiratory diseases, and 36 stakeholders with knowledge and experience in disasters. Data collection was carried out employing semi-structured interviews. Data analysis was performed using Graneheim and Lundman method. RESULTS: Four major challenges in providing care to patients with diabetes and chronic respiratory diseases during natural disasters include integrated management, physical, psychosocial health, health literacy and the behavior and barriers to healthcare delivery. CONCLUSIONS: Developing countermeasures against medical monitoring system shutdown in order to detect medical needs and problems faced by chronic disease patients including those with diabetes and chronic obstructive pulmonary disease (COPD), is essential in preparedness for future disasters. Developing effective solutions may result in improved preparedness and better planning of diabetic and COPD patients for disasters.

This study assessed the effects of movement-based interventions on the complexity of postural changes during prolonged standing. Twenty participants, equally distributed in gender and standing work experience (SWE), completed three simulated prolonged standing sessions: without movement (control), leg exercise and footrest. The amount and complexity of variability in the centre of pressure (COP) and lumbar curvature angle were quantified using linear and nonlinear tools. Lower leg swelling and back/leg discomfort were also monitored. Participants in the SWE group showed significantly greater postural complexity during the standing. Regular leg exercise resulted in significantly higher postural complexity and lower leg discomfort and swelling. The footrest led to significant changes in amount of COP variability. Both interventions significantly reduced back discomfort. Overall, the nonlinear analysis of postural changes provided different findings compared to linear ones, considering the standing time, interventions and standing job experience. Nonlinear results were consistent with leg discomfort and swelling.Practitioner summary: The effect of movement-based interventions on dynamics of postural alterations over prolonged standing were characterised using nonlinear techniques. The effect of standing work experience was also considered. Previous experience of standing jobs and leg movements increase the complexity of postural behaviour over standing period.

BACKGROUND: Elevated blood pressure is associated with cardiovascular disease, stroke and chronic kidney disease. In this study, we examined the socioeconomic inequality and its related factors in prevalence, Awareness, Treatment and Control (ATC) of hypertension (HTN) in Iran. METHOD: The study used data from the recruitment phase of The Prospective Epidemiological Research Studies in IrAN (PERSIAN). A sample of 162,842 adults aged > = 35 years was analyzed. HTN was defined according to the Joint National Committee)JNC-7(. socioeconomic inequality was measured using concentration index (Cn) and curve. RESULTS: The mean age of participants was 49.38(SD = ± 9.14) years and 44.74% of the them were men. The prevalence of HTN in the total population was 22.3%(95% CI: 20.6%; 24.1%), and 18.8%(95% CI: 16.8%; 20.9%) and 25.2%(95% CI: 24.2%; 27.7%) in men and women, respectively. The percentage of awareness treatment and control among individuals with HTN were 77.5%(95% CI: 73.3%; 81.8%), 82.2%(95% CI: 70.2%; 81.6%) and 75.9%(95% CI: 70.2%; 81.6%), respectively. The Cn for prevalence of HTN was -0.084. Two factors, age (58.46%) and wealth (32.40%), contributed most to the socioeconomic inequality in the prevalence of HTN. CONCLUSION: The prevalence of HTN was higher among low-SES individuals, who also showed higher levels of awareness. However, treatment and control of HTN were more concentrated among those who had higher levels of SES, indicating that people at a higher risk of adverse event related to HTN (the low SES individuals) are not benefiting from the advantage of treatment and control of HTN. Such a gap between diagnosis (prevalence) and control (treatment and control) of HTN needs to be addressed by public health policymakers.

BACKGROUND: The first large serosurvey in Iran found a SARS-CoV-2 antibody seroprevalence of 17.1% among the general population in the first wave of the epidemic by April, 2020. The purpose of the current study was to assess the seroprevalence of COVID-19 infection among Iranian general population after the third wave of the disease. METHODS: This population-based cross-sectional study was conducted on 7411 individuals aged ≥10 years old in 16 cities across 15 provinces in Iran between January and March, 2021. We randomly sampled individuals registered in the Iranian electronic health record system based on their national identification numbers and invited them by telephone to a healthcare center for data collection. Presence of SARS-CoV-2-specific IgG and IgM antibodies was assessed using the SARS-CoV-2 ELISA kits. The participants were also asked about their recent COVID-19-related symptoms, including cough, fever, chills, sore throat, headache, dyspnea, diarrhea, anosmia, conjunctivitis, weakness, myalgia, arthralgia, altered level of consciousness, and chest pain. The seroprevalence was estimated after adjustment for population weighting and test performance. RESULTS: The overall population-weighted seroprevalence adjusted for test performance was 34.2% (95% CI 31.0-37.3), with an estimated 7,667,874 (95% CI 6,950,412-8,362,915) infected individuals from the 16 cities. The seroprevalence varied between the cities, from the highest estimate in Tabriz (39.2% [95% CI 33.0-45.5]) to the lowest estimate in Kerman (16.0% [95% CI 10.7-21.4]). In the 16 cities studied, 50.9% of the seropositive individuals did not report a history of symptoms suggestive of COVID-19, implying an estimation of 3,902,948 (95% CI 3,537,760-4,256,724) asymptomatic infected individuals. CONCLUSIONS: Nearly one in three individuals were exposed to SARS-CoV-2 in the studied cities by March 2021. The seroprevalence increased about two-fold between April, 2020, and March, 2021.

OBJECTIVE: This study aims to explore a public volunteer's hospital response model in natural disasters in Iran. METHODS: This study employed grounded theory using the Strauss and Corbin 2008 method and data analysis was carried out in three steps, namely open, axial, and selective coding. The present qualitative study was done using semi-structured interviews with 36 participants who were on two levels and with different experiences in responding to emergencies and disasters as "public volunteers" and "experts". National and local experts were comprised of professors in the field of disaster management, hospital managers, Red Crescent experts, staff and managers of Iran Ministry of Health and Medical Education. RESULTS: The main concept of the paradigm model was "policy gap and inefficiency" in the management of public volunteers, which was rooted in political factions, ethnicity, regulations, and elites. The policy gap and inefficiency led to chaos and "crises over crises." Overcoming the policy gap will result in hospital disaster resilience. Meanwhile, the model covered the causal, contextual, and intervening conditions, strategies, and consequences in relation to the public volunteers' hospital response phase. CONCLUSIONS: The current public volunteers' hospital in Iran suffered from the lack of a coherent, comprehensive, and forward-looking plan for their response. The most important beneficiaries of this paradigm model will be for health policy-makers, to clarify the main culprits of creating policy gap and inefficiency in Iran and other countries with a similar context. It can guide the decision-makings in upstream documents on the public volunteers. Further research should carried out to improve the understanding of the supportive legal framework, building the culture of volunteering, and enhancing volunteers' retention rate.

BACKGROUND: Cohort studies play essential roles in assessing causality, appropriate interventions. The study, Post-crash Prospective Epidemiological Research Studies in IrAN Traffic Safety and Health Cohort, aims to investigate the common health consequences of road traffic injuries (RTIs) postcrash through multiple follow-ups. METHODS: This protocol study was designed to analyse human, vehicle and environmental factors as exposures relating to postcrash outcomes (injury, disability, death, property damage, quality of life, etc). Population sources include registered injured people and followed up healthy people in precrash cohort experienced RTIs. It includes four first-year follow-ups, 1 month (phone-based), 3 months (in-person, video/phone call), 6 and 12 months (phone-based) after crash. Then, 24-month and 36-month follow-ups will be conducted triennially. Various questionnaires such as Post-traumatic Stress Disorder Questionnaire, Patient Health Questionnaire, WHO Disability Assessment Schedules, Cost-related Information, etc are completed. Counselling with a psychiatrist and a medical visit by a practitioner are provided accompanied by extra tools (simulator-based driving assessment, and psychophysiological tests). Through preliminary recruitment plan, 5807, 2905, 2247 and 1051 subjects have been enrolled, respectively at the baseline, first, second and third follow-ups by now. At baseline, cars and motorcycles accounted for over 30% and 25% of RTIs. At first follow-up, 27% of participants were pedestrians engaged mostly in car crashes. Around a fourth of injuries were single injuries. Car occupants were injured in 40% of collisions. DISCUSSION: The study provides an opportunity to investigate physical-psychosocial outcomes of RTIs, predictors and patterns at follow-up phases postinjury through longitudinal assessments, to provide advocates for evidence-based safety national policy-making.

In this cross-sectional population-based study, we used the baseline data of the Prospective Epidemiologic Research Studies in IrAN cohort study collected in Iran from 2014 to 2020. The main outcomes were the prevalence of hypertension and proportion of awareness, treatment, and control based on the 2017 ACC/AHA guideline compared to the seventh report of the Joint National Committee (JNC7). Of the total of 163,770 participants, aged 35-70 years, 55.2% were female. The sex-age standardized prevalence of hypertension was 22.3% (95% CI 20.6, 24.1) based on the JNC7 guideline and 36.5% (31.1, 41.8) based on the ACC/AHA guideline. A total of 24,312 participants [14.1% (10.1, 18.1)] were newly diagnosed based on the ACC/AHA guideline. Compared to adults diagnosed with hypertension based on the JNC7 guideline, the newly diagnosed participants were mainly young literate males who had low levels of risk factors and were free from conventional comorbidities of hypertension. About 30.7% (25.9, 35.4) of them (4.3% of the entire population) were eligible for pharmacologic intervention based on the ACC/AHA guideline. Implementation of the new guideline may impose additional burden on health systems. However, early detection and management of elevated blood pressure may reduce the ultimate burden of hypertension in Iran.

BACKGROUND: So far, no comprehensive studies have been performed to assess burden and determinants of anemia in Iran. In the present study, we aimed to answer this query using the data obtained from the Prospective Epidemiological Research Studies in IrAN (PERSIAN). METHODS: In this cross-sectional study, we included 161,686 adult participants (aged 35 years and older) from 16 provinces of Iran. Anemia was defined as a hemoglobin concentration of <13 g/dL in males and <12 g/dL in females. To evaluate the association between anemia and different factors, we used the multivariable Poisson regression analysis with robust variance by applying adjusted prevalence ratio (PR) with 95% confidence interval (CI). RESULTS: Of the total number of subjects, 72,387 (44.77%) were male and others were female. Mean age was 49.39±9.15 years old. The overall age- and sex-standardized prevalence of anemia was 8.83% (95% CI: 8.70-8.96%) in the included population. The highest and the lowest age- and sex-standardized prevalence of anemia pertained to Hormozgan (37.41%, 95% CI: 35.97-38.85%) and Kurdistan (4.57%, 95% CI: 3.87-5.27%) provinces, respectively. Being female (PR = 2.97), rural residence (PR = 1.24), being retired (PR = 1.53) and housewife (PR = 1.11), third and fourth wealth status quartiles (PR = 1.09 and PR = 1.11, respectively), being underweight (PR = 1.49), drug user (PR = 1.35), inadequate sleep (PR = 1.16), poor physical activity (PR = 1.15), diabetes (PR = 1.09), renal failure (PR = 2.24), and cancer (PR = 1.35) were associated with increased risk of anemia. On the other hand, illiteracy (PR = 0.79) and abdominal obesity (PR = 0.77) decreased the risk of anemia. CONCLUSIONS: According to the results, a variable prevalence of anemia was observed across the included provinces. We tried to provide an informative report on anemia prevalence for health professionals and authorities to take measures for identification and management of the cases of anemia in high-prevalence areas.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led many healthcare systems to become overwhelmed, and caused many frontline providers to feel fatigued and exhausted and experience severe emotional trauma. Nurses are the largest group of the world's frontline providers and it is clear that their resilience to threatening factors is critical in the current crisis. Therefore, the purpose of this study was to determine the level of resilience in nurses working in COVID-19 centers in Iran. METHODS: A cross-sectional study was conducted with 250 nurses working at three COVID-19 centers in northwest Iran. The participants were recruited using simple random sampling. The Connor-Davidson Resilience Scale was used to collect the data. RESULTS: The highest level of resilience was related to spiritual influences, while the lowest was the trust in their instincts and tolerance of negative emotions. Furthermore, the level of resilience was significantly higher in nurses with better family support (p < 0.01). CONCLUSION: Given the role of resilience in nurses' mental health, it is vital to support the nursing staff in critical situations and improve their resilience by focusing particularly on psychological and spiritual support.

OBJECTIVE: People with NCDs are particularly vulnerable to disasters. This research systematically reviewed reports describing studies on the status of patients with NCDs before, during and after disasters. METHOD: Relevant articles published from 1997 to 2019 were collected by searching the Scopus, PubMed, and Science Direct databases. We specifically examined reports describing NCDs and including the key words 'Non-Communicable Disease and Disasters.' NCDs include cardiovascular, respiratory, diabetes and cancer diseases. RESULTS: The review identified 42 relevant articles. Most of the included studies were found to have described the conditions of patients with NCDs after disasters - 14 (13.3%), during disasters - 11 (26.2%), before disasters - 6 (14.3%), within all stages of disasters: before, during and after - 6 (14.3%), only during and after disasters - 4 (9.5%), and includes before and during disasters - 1 (2.4%). CONCLUSION: NCDs pose major health issues in disasters. Development of strong counter measures against the interruption of treatment, as well as surveillance systems to ascertain medical needs for NCDs are necessary as preparation for future disasters.

BACKGROUND: Hand anthropometry is useful for designing manual systems such as hand tools, controls, and gloves. There are limited published data on the hand dimensions of Iranian male and female adults. OBJECTIVE: This study was undertaken to measure the hand anthropometric dimensions in Iranian adults to compare data between two genders and also with the corresponding data from other nationalities. METHODS: A total of 34 dimensions of the right hand were measured in 217 male and 128 female adults using a digital caliper and tape. The mean, standard deviation, and the main percentiles are summarized in a table and the mean of each dimension is compared by independent t-tests between genders. Hand dimensions are compared between Iranian and other nationalities such as North Colombian, Korean, Turkish, Nigerian, Bangladeshi, Jordanian, and Vietnamese using the published data. RESULTS: Females had significantly smaller hand dimensions than males in all dimensions ranged from 4.21%to 18.16%, with the largest differences in hand breadths. Compared with other nationalities, the Iranian male and female adults had wider (greater breadth and circumferences) hands with shorter fingers. CONCLUSIONS: The results showed significant differences of hand anthropometry between Iranian and other nationalities which should be included in the design and selection of hand tools for Iranian population.

BACKGROUND: Patients with non-communicable diseases are vulnerable to disasters. This is a systematic review describing the impact of disasters on non-communicable diseases. METHODS: A systematic review was conducted using PRISMA standards. Relevant articles published from 1997 to 2019 collected by searching the Scopus, PubMed, Science Direct, databases. We specifically examined reports describing NCDs and including the key words "non-communicable disease and Disasters". NCDs included cardiovascular, respiratory, diabetes, cancer and mental health diseases. RESULTS: Of the 663 studies identified, only 48 articles met all the eligibility criteria. Most studies have shown the impact of all natural disasters on non-communicable diseases (39.8% n=19). The largest study was the effect of earthquakes on non-communicable diseases (29.2% n=14). For the NCDs targeted by this research, most of the included studies were a combination of four diseases: cardiovascular disease, respiratory disease, diabetes and cancer (44% n=21). Followed by cardiovascular disease (14.6% n=7), chronic respiratory disease (12.5% n=6), diabetes and cancer (6.2% n=3) and mental health (12.5% n=6). CONCLUSION: The incidence of disasters affects the management of treatment and care for patients with NCDs. Specific measures include a multi-part approach to ensuring that patients with non-communicable diseases have access to life-saving services during and after disasters. The approach of the health system should be expanded from traditional approaches to disasters and requires comprehensive planning of health care by policy makers and health professionals to develop effective strategies to enable patients to access medical, therapeutic and diagnostic services in natural disasters.
RESUMO
BACKGROUND: Volunteers' presence, as a critical issue in hospital response to disasters and emergencies, helps to readiness and quick response to the phenomena, preventing deaths caused by such incidences. This study aimed to determine the main factors affecting popular volunteers' presence in hospital response to disasters and emergencies in Iran. METHODS: This qualitative study, conducted on 31 semi-structured interviews during the years 2019 and 2020, concerning emergency specialist working in various health organization nationwide between June 2019 and April 2020. The non-structured and semi-structured interviews were adopted to gather concept code and analyzed using Graneheim recommendation method. RESULTS: Four main categories, identified as effective factors on volunteers' presence in hospital response to disasters and emergencies, including nine subcategories: (1) organizing and managing volunteers (with two sub-categories: (a) calling and registering volunteers, and (b) identifying volunteers' ability); (2) organizational structure (with two sub-categories: (a) operational planning and (b) coordination and communication); (3) training (with two sub-categories: (a) training in disasters and (b) volunteer training); and (4) volunteer challenges (with three sub-categories: (a) volunteer interaction with organizations, (b) volunteer logistics, and (c) volunteering culture). CONCLUSIONS: Exploring effective factors as regards volunteers' presence in hospital response phase in disasters to adopt a policy based on the experiences of managers and heads of health can help planners to provide effective design and implementation. It can scientifically contribute to disaster risk management and hospital emergency response in Iran.

PURPOSE: Nonlinear analysis techniques provide a powerful approach to explore dynamics of posture-related time-varying signals. The aim of this study was to investigate the fundamental interactions between postural variability structure and discomfort development during prolonged standing. METHODS: Twenty participants, with equal distribution for gender and standing work experience (SWE), completed a simulated long-term standing test. Low back and legs discomfort, center of pressure, lumbar curvature, and EMG activity of trunk and leg muscles were monitored. Nonlinear measures including largest lyapunov exponent, multi-scale entropy, and detrended fluctuation analysis were applied to characterize the variability structure (i.e., complexity) in each signal. The size (i.e., amount) of variability was also computed using traditional linear metrics. RESULTS: With progress of low back and legs discomfort over standing periods, significant lower levels were perceived by the participants having SWE. The amount of variability in all signals (except external oblique EMG activity) were significantly increased with the time progress for all participants. The structure of variability in most signals demonstrated a lower complexity (more regularity) with fractal properties that deviated from 1/f noise. The SWE group showed a higher complexity levels. CONCLUSIONS: Overall, the findings verified variations in structure and amount of the postural variability. However, nonlinear analysis identified postural strategies according to the perceived discomfort in a different way. These results provide supports for future application of nonlinear tools in evaluating standing tasks and related ergonomics interventions as it allows further insight into how discomfort development impact the structure of postural changes.

BACKGROUND: NCDs require an ongoing management for optimal outcomes, which is challenging in emergency settings, because natural disasters increase the risk of acute NCD exacerbations and lead to health systems' inability to respond. This study aims to develop a protocol for a systematic review on non-communicable diseases in natural disaster settings. METHODS: This systematic review protocol is submitted to the International Prospective Register of Systematic Reviews (Registration No. CRD42020164032). The electronic databases to be used in this study include: Medline, Scopus, Web of Science, Clinical Key, CINAHL, EBSCO, Ovid, EMBASE, ProQuest, Google Scholar, Cochrane Library (Cochrane database of systematic reviews; Cochrane central Register of controlled Trials). Records from 1997 to 2019 are subject to this investigation. Three independent researchers will review the titles, abstracts, and full texts of articles eligible for inclusion, and if not matched, they will be reviewed by a final fourth reviewer. The proposed systematic review will be reported in accordance with the reporting guideline provided in the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) statement. We select studies based on: PICOs (Participants, Interventions, Comparators, and Outcomes). RESULTS: This systematic review identifies any impacts of natural disasters on patients with NCDs in three stages i.e. before, during and in the aftermath of natural disasters. CONCLUSIONS: A comprehensive response to NCD management in natural disasters is an important but neglected aspect of non-communicable disease control and humanitarian response, which can significantly reduce the potential risk of morbidity and mortality associated with natural disasters.

BACKGROUND: Echinococcus granulosus and Toxocara spp., the causative agents of hydatid cyst and toxocariasis in humans and animals, are zoonotic infections with medical and veterinary significance respectively. AIM: Herein, we aimed to investigate the seroprevalence of toxocariasis and cystic echinococcosis in Urmia municipal workers (gardeners and sweepers) in 2018 using ELISA assay. OBJECTIVE: There is no precise report on the seroprevalence of toxocariasis and cystic echinococcosis in Urmia municipal workers using ELISA assay. Therefore, this study found an opportunity to investigate this subject. METHODS: A total of 220 blood samples were obtained from municipal workers with an average age of 41.31 ± 9.42. Commercial anti-Toxocara canis and hydatid cyst ELISA kits were used to assess the seroprevalence rates. RESULTS: Approximately, 14.5% and 2.3% of individuals were seropositive for toxocariasis and hydatidosis, respectively. Consuming unboiled milk and/or raw/uncooked meat and rural conditions are risk factors for toxocariasis. Regarding hydatidosis, consuming unwashed vegetables was the only statistically significant risk factor. Toxocara infection (p = 0.01), but not hydatid cyst (p = 0.05), is more prevalent among sweepers than municipal gardeners. CONCLUSION: Due to the occupational condition of municipal workers, they are exposed to many infectious agents; thus, more researches should be done on these populations.
