Brucellosis is the most common zoonosis and is a health issue in Iran. Considering this disease is endemic in Qaen, this study intended to investigate the epidemiologic characteristics of brucellosis during 2015-2021. This cross-sectional study was conducted on 421 brucellosis patients, based on the information from Qaen Health Center from 2015 to 2021. To describe the data, frequency, mean, and standard deviation indices and to analyze the data, Chi-square and T-test statistical tests were utilized using SPSS software version 21. The incidence rate was calculated based on 100,000 at-risk populations per year. The average incidence rate of brucellosis from 2015 to 2021 was 135 per 100,000. The highest incidence rate was 156 per 100,000 people in 2021, and the lowest was 20.58 per 100,000 in 2017. The mean age of brucellosis patients was 36.78 ± 19.85  years. The most frequent clinical symptoms were musculoskeletal pain in 317 cases (75.3%) and fever in 160 cases (38%). The consumption history of unpasteurized dairy products such as milk and cheese was 33% and 27%, respectively. Farmers and ranchers, with 239 cases (56.7%), and the rural living population, with 282 cases (67%), were the most frequent cases of brucellosis. The incidence rate of brucellosis in Qaen has an upward trend and is higher than the provincial and national averages. According to the latest national guidelines, this county is classified as a highly polluted region.

The emergence and continuity of Corona has forced universities and higher education centers to change their educational strategy to take appropriate and consistent action to improve their educational programs. Due to the importance of e-learning and e-learning in response to these conditions, the present study investigated the experience of students of Hamadan University of Medical Sciences from e-learning in the Covid-19 crisis condition.

This was a qualitative research with an interpretive phenomenological approach. The purposeful sampling method was used. Semi-structured interviews were used to collect data. After the thirteenth interview, the theoretical saturation of the data was achieved and the interview process with the sixteenth person was completed. In order to analyze the text of the interviews, the Colaizzi method was used.

From the analysis of the obtained data, three main themes: “Communication and interaction” with five sub-themes (lack of proper interaction between student/professor and student/student, lack of motivation, security and mental health, knowledge sharing and efficiency atmosphere in time and cost), “Management of time and learning style” with six sub-themes (low quality of teaching, stress, access and provision of resources, exam health, gaining experience and skills and opportunity to learn again and innovation in education) and “Infrastructure and technical facilities” were extracted with three sub-themes (weak support, ignoring educational equality and promoting media literacy). Weak interaction between professor and student, increasing level of anxiety and individual responsibility to achieve success in learning and weak technical and management infrastructure were the main challenges obtained from these three themes. Providing a platform for research, self-regulation and self-management in learning, increasing the knowledge and skills of information and communication technology are among the opportunities that are included in these themes.

The results of the current research require attention to the approach of interaction and communication between the learner and the learner, to review the methods of teaching and skill-learning, to improve the quality of electronic learning and to prepare suitable infrastructures for optimal use of electronic learning.
