Background: Brucellosis, as a zoonotic disease, is widespread among humans and animal andcontinues to be a major public health problem. The present study aimed to analyze the trends and epidemiological characteristics of human brucellosis in Ain Témouchent (Western Algeria).Methods: In this registry-based longitudinal study, data on the reported new cases of brucellosis for five years (2014 to 2019) were obtained from the provincial notifiable diseases surveillance system of Ain Temouchent. Using official population data, we calculated the incidence rate per 100,000 inhabitants.Results: From 2014 to 2019, 599 cases of brucellosis cases were notified in Ain Temouchent province (mean annual incidence: 26.37 cases/100,000 inhabitants). The yearly notification peaked in 2014 (n=170 cases). The highest incidence was reported for males (56%) compared to females (44%) with a sex ratio of 1.29. Regarding age, the highest incidence of notified cases for brucellosis was in the group aged 25-44 years and over, accounting for 37,73% of all notified cases. The lowest incidence was found in the age group between 0-14 years with 11.52%. The disease peaked in May with 139 cases. The geographical distribution indicated that the highest risk area of human brucellosis was Hammam Bou Hadjar and Ain Larabaa region.Conclusion: Our findings showed a high prevalence of human brucellosis in Ain Témouchent, with gender, age, and seasonal changes as the main risk factors for human brucellosis.

Background: Brucellosis, a zoonotic disease, poses a significant health and economic challenge in many parts of the world, including Mediterranean and Middle Eastern countries. This study aimed to investigate the risk factors and recurrence of brucellosis, focusing on demographic variables such as age, gender, occupation, place of residence, and the spatiotemporal pattern of the population.Methods: The study design was cross-sectional.The authors enrolled all Brucella cases registered in the infectious disease surveillance system of Fars province from 2014 to 2018 in the study. They performed a multivariate analysis of the disease risk factors using a Poisson regression model and a multivariate analysis of the risk factors associated with brucellosis recurrence using a logistic regression model.Results: The incidence of brucellosis in Fars province exhibited a decreasing trend. The findings revealed that the sex ratio of patients who consumed unpasteurized dairy products, the mean age of patients per month, and the proportion of people living in rural areas relative to the total number of patients with brucellosis were significantly associated with the risk of brucellosis. Moreover, the probability of disease recurrence was higher in colder seasons compared to spring.Conclusion: A higher ratio of lightweight livestock to heavyweight livestock was identified as a risk factor for brucellosis, indicating the more significant role of lightweight livestock in the incidence of brucellosis in Fars province. Therefore, controlling the disease in lightweight livestock is of paramount importance, and the vaccination of these livestock should be more strictly monitored and implemented.

Background: The aim of this study is to investigate the epidemiological indicators of brucellosis in Ilam province, west of Iran, during the years 2011 to 2018. Methods: This descriptive cross-sectional analytical study was performed on 1,002 patients with brucellosis in Ilam province, west of Iran. People with a Wright test greater than 1.80 or a positive 2ME test who were diagnosed with brucellosis were followed up and treated. Data were analyzed using SPSS software version 21 and Excel 2007. Results: 1002 patients with brucellosis were diagnosed, 566 of whom were male (56.5%) and 436 were female (43.5%). The mean age at the onset of the disease was 38.11 ± 19.61 in men, 41.73 ± 15.67 in women, and39.94 ±17.81 in both sexes. The incidence of brucellosis in 2011 was 20.44 per 100,000 (22.30 per 100,000 in men and 18.53 per 100,000 in women), which dropped to 15.94 per 100,000 in 2018. Regarding the season, most cases of the disease were observed in summer (31%), spring (24.7%), winter (23.6%), and autumn (20.7%), respectively. Conclusion: The results showed that the age of the onset of the disease was middle age, when individuals are active labor and human capital working in a community. Therefore, improving cross-sectoral and intra-sectoral cooperation and promoting effective education for prevention seem necessary.

Introduction: Despite the provision of health care in Iran, brucellosis is still an endemic disease, so this study was carried out to determine the epidemiology of brucellosis in Andimeshk city during 2001-2016. Materials and Methods: This cross-sectional study was conducted on patients with brucellosis, which were reported by governmental and non-governmental departments and received relevant diagnostic and laboratory information after receiving reports from patients. The obtained information was entered in the survey form. Sampling was done by census. SPSS version 20 was applied for analysis of data using descriptive statistics as well as the chi-square and independent t-test; a significant level of 0.05 was considered. Results: In the study period, there were 713 patients with brucellosis in Andimeshk. There were 390 males and 324 females with a male to female ratio of 1.02:1. The age of the patients ranged from 1 to 74 years with a mean of 31.19±17.03 years. The annual incidence rate per 100,000 persons was 24.42. There was a statistically significant association (p <0.05) between sex and exposure to infected milk and cattle. Also, the results showed that there was no statistically significant association (p>0.05) between the infected milk and job, year, season and month. Conclusion: In conclusion, the findings of this study showed that the incidence of brucellosis was higher among males, young people, and dairy farmers. Therefore, continuous surveillance and efforts are required to further decrease the cases of brucellosis.
