4. Health promotion and education: The development and implementation of programs and campaigns to promote healthy behaviors and prevent disease.

5. Health policy and management: The development and implementation of policies and programs to improve the delivery and accessibility of healthcare services.

6. Global health: The study of health issues that transcend national boundaries, and the development of strategies to address these issues on a global scale.

Types of public health work include:

1. Disease surveillance: Monitoring and tracking the spread of infectious diseases and other health threats in populations.

2. Health education and promotion: Developing and implementing programs to educate individuals and communities about healthy behaviors and disease prevention.

3. Policy development: Working with government agencies and other stakeholders to develop and implement policies that promote public health.

4. Research: Conducting studies to better understand the causes of disease and identify effective interventions to improve health outcomes.
