Volunteers are an organization's most complete human resource to hold a successful sporting event. Maintaining a volunteer workforce and motivating volunteers to continue their activities is one of the most important tasks of sporting event managers. This study aimed to investigate how volunteers' involvement in the 14th Sports Olympiad for University Students in Iran affected their behavior. For this purpose, 157 volunteers present at the 14th Sports Olympiad for University Students in Iran were randomly selected as the research sample. Researchers collected data using the Zitsmal et al. (1996) Modified Scale of Behavioral Intentions, Doherty's community involvement scale (2009), and Zaichkowsky's Event Involvement Questionnaire (1994). In order to test the hypotheses, structural equation modeling was used. The results showed that the measurement model has appropriate internal consistency, convergent validity and Discriminant validity. It was confirmed that all variables used in the study were accurate. In the structural model results, the index for determining the coefficient of behavioral intentions was 0.44. Showed that social participation and event participation had a moderate and positive correlation with each other (0.40), and community involvement and event involvement, respectively, with path coefficients of 0.45 and 0.34, had an effect on behavioral intentions, so it can be concluded that understanding the psychological and behavioral aspects of volunteers, such as types of involvement, helps sports organizations in attracting volunteers. In this way, they can maximize the willingness of volunteers to involvement in the future.

Backgrounds: This study aimed to determine community-initiated Lassa fever prevention and control strategies in Africa.
Materials & Methods: Literature search was performed on four databases, including PubMed, Google Scholar, African Journal OnLine (AJOL), and BioMed Central, using different combinations of the following search terms. A three-stage methodology was employed to conduct the study. At first, related articles were identified using pre-defined key terms, such as Lassa fever, Lassa fever control, Lassa fever prevention, community engagement and Lassa fever, and community participation and Lassa fever. Thereafter, articles were screened to remove duplicates and articles not relevant to the study objectives.
Findings: Community mobilization and sensitization and risk communication were some of the community-directed activities towards Lassa fever prevention and control. Also, stakeholders’ advocacy and engagement, rodent control practices, environmental sanitation, and proper food processing and preservation were practiced to prevent Lassa fever. In addition, a referral mechanism from the community to the health facility was constituted through the engagement of community health workers.
Conclusion: Health program managers should strive to provoke coordinated and sustainable community-initiated efforts to improve rodent preventive and control measures. Strategies should be developed and implemented to promote environmental sanitation and restrict cultural practices facilitating contact with rodents or infected persons.
