Abstract Background: Ross River virus (RRV) is responsible for the most common vector-borne disease of humans reported in Australia. The virus circulates in enzootic cycles between multiple species of mosquitoes, wildlife reservoir hosts and humans. Despite regular outbreaks, ongoing morbidity and substantial economic costs, the underlying determinants of epidemics remain unclear. Public health concern about RRV has recently increased due to rising incidence rates in Australian urban centres, along with increased circulation in Pacific Island countries. Australia experienced its largest recorded outbreak of 9,544 cases in 2015, with the majority reported from South East Queensland (SEQ). We aimed to provide a detailed analysis of disease trends and explore potential links between disease patterns and transmission pathways of RRV. Methods: We assessed the spatial and temporal distribution of notified RRV cases, and associated epidemiological features in SEQ, from 2001-2016. This included fine-scale analysis of disease patterns across the suburbs of the capital city of Brisbane, and those of 8 adjacent Local Government Areas, and host spot analyses to identify locations with significantly high incidence. Results: The mean annual incidence rate for the region was 41/100,000 with a consistent seasonal peak in cases between February and May. The highest RRV incidence was in adults aged from 30-64 years (mean incidence rate: 59/100,000), and females had higher incidence rates than males (mean incidence rates: 44/100,000 and 34/100,000, respectively). Spatial patterns of disease were heterogeneous between years, and there was a wide distribution of disease across both urban and rural areas of SEQ. Overall, the highest incidence rates were reported from predominantly rural suburbs to the north of Brisbane City, with significant hot spots located in peri-urban suburbs where residential, agricultural and conserved natural land use types intersect. Conclusions: Although RRV is endemic across all of SEQ, transmission is most concentrated in areas where urban and peri-urban environments intersect. The drivers of RRV transmission across rural-urban landscapes should be prioritised for further investigation, including identification of specific vectors and hosts that mediate human spillover.

Abstract Pneumoconiosis has the potential to cause progressive and permanent physical disability. And continues to be one of major public health concern across the world. However, our literature searches identified a scarcity of data about global prevalence of pneumoconiosis. Accurate data on the incidence of pneumoconiosis is critical for health resource planning and health policy development. We therefore aimed to determine the pattern of pneumoconiosis incidence and temporal trends. Methods: Annual incident cases and age standardized incidence rates on pneumoconiosis etiology between 1990-2017 were collected from the Global Burden of Disease Study 2017. We calculate the average annual percentage changes of age standardized incidence rates by sex, region, and etiology to determine incidence trends of pneumoconiosis. Results: Globally, the number of pneumoconiosis cases increased 66.0% from 36,186 in 1990 to 60,055 in 2017. The overall age standardized incidence rate decreased by an average 0.6% (95% CI: 0.5%, 0.6%) per year in the same period. The age standardized incidence rate of silicosis, asbestosis, and other pneumoconiosis decreased between 1990 and 2017. The corresponding average annual percentage changes were -0.8%, -0.9%, and -0.5%, respectively. The age standardized incidence rate of asbestosis displayed an increasing trend. At the same time, we also found a significant negative association was found between average annual percentage changes and socio-demographic indexs when the socio-demographic index above 0.7. Conclusions: Pneumoconiosis remains a major occupational health illnesses in the world. Incidence patterns of pneumoconiosis caused by different etiologies were heterogeneous across regions and countries. We observed an unfavorable trend that asbestosis was predominant in countries with a high socio-demographic index, though we have attained great achievements in silicosis and coal workers’ pneumoconiosis prevention. The information in this study suggests that some countries should establish more targeted and specific strategies to forestall the increase in pneumoconiosis.

Abstract Background:Cutaneous leishmaniasis (CL) is an important public health concern worldwide. Iran is among the most CL-affected countries, being listed as one of the first six endemic countries in the world. In order to develop targeted interventions, we performed a spatial-time visualization of CL cases in an urban area to identify high-risk and low-risk areas during 2016-2019.Methods:This cross-sectional study was conducted in the city of Mashhad. Patient data were gathered from Mashhad health centers. All cases (n=2425) were diagnosed in two stages; the initial diagnosis was based on clinical findings. Subsequently, clinical manifestation was confirmed by parasitological tests. The data were aggregated at the neighborhood and district levels and smoothed CL incidence rates per 100,000 individuals were calculated using the spatial empirical Bayesian approach. Furthermore, we used the Anselin Local Moran’s I statistic to identify clusters and outliers of CL distribution during 2016-2019 in Mashhad. Results:The overall incidence rates decreased from 34.6 per 100,000 in 2016 to 19.9 per 100,000 individuals in 2019. Both cluster analyses by crude incidence rate and smoothed incidence rate identified high-risk areas in southwestern Mashhad over the study period. Furthermore, the analyses revealed low-risk areas in northeastern Mashhad over the same 3-year period.Conclusions:The southwestern area of Mashhad had the highest CL incidence rates. This piece of information might be of value to design tailored interventions such as running effective resource allocation models, informed control plans and implementation of efficient surveillance systems. Furthermore, this study generates new hypotheses to test potential relationships between socio-economic and environmental risk factors and incidence of CL in areas with higher associated risks.

Background/Aim. Non-melanoma skin cancers (NMSC) are ones of the most rapidly increasing cancers worldwide. Although NMSCs have a relatively low mortality rate, they are an important public health concern and the most costly cancers in many countries. The two main objectives in this study were: first, to analyze the trend of age-standardized incidence rate of NMSCs in Serbia and second, to assess the need for national prevention and control strategy based on analyzed trend. Methods. From the Serbian Cancer Registry, we extracted all cases of NMSCs registered in central Serbia from January 1, 1999 to December 31, 2015. Joinpoint regression analysis was used to define trends and annual percentage change (APC). Results. NMSCs significantly increased for both genders with APC of +2.32% (p < 0.001). Significantly increasing trend of incidence rates was higher in women (APC, +2.63%; p < 0.0001) than in men (APC, +2.01%; p < 0.001). Conclusion. Our results show a continuously increasing incidence rate of NMCS in Serbia. Without the national preventive strategy, current sporadic activities are highly unlikely to result in reducing the growing trends

Objectives.In this study, we have evaluated the lifetime and past-year prevalence of exposure to physical violence among married women in the city of Tehran and urban and rural areas of Hashtgerd.Methods.The target population were noninstitutionalized female citizens, aged 15 years or older, who have at least one history of marriage and who resided in the capital city of Tehran or Hashtgerd County from the summer of 2008 to fall of 2010. We used a multistage sampling method. Tehran’s District Six, a central district in Tehran, was selected as a representative cluster of all municipal districts in Tehran. A total of fifty blocks were randomly selected from this district, from which 1,000 married women aged 15 years or older were interviewed using a cross-sectional design. Data was gathered face-to-face using a structured questionnaire. The lifetime prevalence, past-year prevalence, and related factors of domestic violence were measured. SPSS version 11.5 was used for the analyses.Results.Figures for lifetime prevalence and past-year prevalence were measured to be 38.7% and 6.6%, respectively. The independent effects of marital status and location and type of residency for women, along with education and smoking habits of their spouses, were statistically significant in multivariate logistic regression analysis.Conclusion.Domestic violence is a public health concern in Iran. Based on our findings, we propose that empowering women through education, and improving their ability to find employment and income, along with increasing public awareness of human rights issues through education could lower the prevalence of domestic violence.

Epidemiologic Characteristics

Introduction. The Campylobacter is the most common bacterial cause of foodborne illnesses in high-income countries. In contrast to other infectious diseases, the number of Campylobacter cases has increased in developed countries over the last ten years. A systematic review has been conducted to identify the factors contributing to incidence of Campylobacter infection in developed countries and to estimate it by age, sex, geography, and season.Materials and methods. The review was limited to studies published in English from 2010-2021; eight nationwide surveillance and register-based cohort studies, which met the selection criteria, were included in the review.Results. While the highest incidence of Campylobacter infection was reported among young children living in rural areas, the highest number of Campylobacter cases among adults was recorded in urban settings. Nevertheless, population-wise, children and older adults are most affected, while the incidence rates are higher in males than in females, with cases peaking every summer.Conclusion. Campylobacter infection is a public health concern in high-income countries, being difficult to eradicate and having become an urgent challenge to the existing well-developed surveillance systems. Additionally, the threat of antibiotic resistance in Campylobacter is growing at an alarming rate. The reasons behind Campylobacter affecting more men than women as well as the age and geographic distribution of the infection still need thorough research.
