Common global health programs focus on disease prevention and control, health promotion, capacity building, and policy advocacy. Examples include vaccination campaigns, nutrition interventions, and health worker training.

There are many ways for students to engage in global health, such as taking relevant courses, participating in research projects, joining student organizations, and pursuing internships or volunteer opportunities with global health organizations.

Funding for global health initiatives comes from various sources, including government agencies, private foundations, multilateral organizations, and individual donors. Scholarships and financial aid may be available for students interested in global health.

Challenges include limited resources, weak health systems, sociocultural barriers, political instability, and competing priorities. Effective global health programs must be context-specific, sustainable, and responsive to local needs.
