“…5,11 The results of this study showed that there was a significant relationship between the mean age and exposure to infected animals; this finding was consistent with the results of the study conducted by Kashefi et al 23 This study showed that outbreaks are more common in spring and summer (from May to September). This is consistent with the results of other studies, including Mohammedan, 19 Zemestani et al 18 , Soleimani et al 22 , and Maleki et al 29 Moreover, since 2011 the number of infected people showed a strong upward trend and increased from 305 in 2011 to 755 people in 2014.…”

Background and aims: Brucellosis is one of the most common infectious diseases in both humans and animals. It has been controlled in developed countries; however, it is still regarded as a public health problem in developing countries including Iran. The aim of this study was to investigate the epidemiology of human brucellosis in Isfahan province. Methods: The present study is a cross-sectional descriptive study investigating the epidemiology of human brucellosis in Isfahan province from 2010 to 2015. Sampling was done using Isfahan’s disease registry database. Chi-square and t test were used for analyzing the data, and all data analyses were performed using SPSS software version 21.0. Results: A total of 3,245 patients were included in this study, and their mean (SD) age was 35.29 (18.00) years. The age group of 15-25 years with a frequency of 23.80% had the highest frequency of the disease. The annual incidence of the disease from 2010 to 2014 shows an increasing trend, reaching from 6.25 to 15 per 100000 people. It was reduced in 2015 and reached 12.25 per 100000. In addition, the highest incidence was observed in July. Conclusion: This study implies that the trend of human brucellosis has been increasing over the years, so it is recommended that people be educated on how to prevent it in humans and animals. The results of this study can help health administrators in the province to more effectively control the disease at the provincial level by identifying high-risk cities and focusing on health care in these areas.

“…Also, in our study, it was reported that the highest and lowest cases of the disease were in the summer and autumn months, respectively. A similar study in north-western Iran showed that the highest prevalence of the disease was in winter and spring [32]. In this regard, Pakzad et al showed that the incidence of the disease increased in early spring to mid-summer, and after that it decreased to the lowest incidence in winter; this is not in the same line with the results of the present study [24].…”

Background: Brucellosis is known in Iran as an endemic disease; however, its incidence is not the same in all provinces and is higher in some areas.Objective: The present study was designed to determine the epidemiological status and trend of brucellosis in the period from 2015 to 2020 in the south of Fars province, Southern Iran.Methods: This is a cross-sectional analytical study. This study included all patients with brucellosis in the period from 2015 to 2020 whose information had been registered in the Infectious Diseases Center of Larestan city. To collect the data, we used a checklist that included information such as age, gender, number of cases by year and month, occupation, and nationality of the patients with brucellosis. The rate of brucellosis incidence during these years was analyzed using the Cochran-Armitage trend test. P-value less than 0.05 was considered significant. Results:The average annual incidence of the disease was 8.94 per 100 000 population. It has decreased from 26.83 (per 100 000 people) in 2015 to 1.83 (per 100 000 people) in 2020. The results of Cochrane-Armitage process test showed that the reduction in the incidence of the disease from 2015 to 2020 was significant (PTrend = 0.001). The trend of the disease by month also showed that the majority of cases occurred between December and February, with the highest incidence of the disease in February (9.93 per 100 000 people) and the lowest in May (1.1 per 100 000 people) (P = 0.001). Conclusion:Although the results of the present study indicated a decrease in the incidence of the disease in the southern region of Fars province, due to the fact that the disease is common between humans and livestock, there is the possibility of scattered and irregular epidemics in each period.

“…Brucellosis has a very broad range of clinical manifestations from asymptomatic infection to a serious debilitating disease with diverse complications; therefore its diagnosis may be challenging [7, 12]. In Iran, brucellosis is an endemic disease, and despite improvement in its control, 16 000 cases of this disease are reported each year [13–16].…”

Brucellosis as a neglected disease in a neglected population: a seroepidemiological study of migratory nomads in the Fars province of Iran

et al. 2016

This study assessed the seroprevalence of brucellosis and its risk factors in migratory nomads in the Fars province of Iran. Active brucellosis was defined as the combination of clinical symptoms, including fever, chills, night sweats, headache, low back pain, arthralgia, or myalgia, and positive laboratory testing, including either a serum agglutination test (SAT) ⩾1:80 with a 2-mercaptoethanol (2-ME) test ⩾1:40, or a SAT <1:80 combined with a positive Coombs Wright test (CWT) at a titre of at least threefold higher than SAT titre results. For the 536 participants, the female (316, 59%) to male (220, 41%) ratio was 1·4 and the participants' mean age was 32·4 ± 18·9 (range 1-96) years. Of all participants, 325 (60·6%) showed clinical symptoms; in symptomatic participants, the Rose Bengal plate test was positive in 33 (6·1%) cases, the SAT was positive in 18 (3·3%) cases, and the 2-ME test was positive in 30 (5·5%) cases. Positive SAT and 2-ME results were seen in 18 (3·3%) cases, but a negative SAT and a positive CWT were found in 36 (6·7%) cases. As a result, active brucellosis was detected in 54 cases, indicating a prevalence of 10% (95% confidence interval 8-12). In conclusion, we determined that brucellosis is a prevalent yet neglected disease in this nomadic population. Brucellosis control is not possible as long as these high-risk populations remain neglected.
