Infectious diseases still occur frequently throughout the world. Hence, a constant vigilance is required to prevent the reappearance of diseases and conditions thought to have been conquered. An essential component of any public health system is disease surveillance because it helps to monitor disease trends over time, detect disease outbreaks and increase the knowledge of risk factors contributing to disease development. Changing lifestyles are giving rise to new threats to public health from infection. Hence, notification is very essential to prevent and control the spread of infection and harmful exposures.

Human activity has transformed environmental health in profound ways. While earlier environmental problems were relatively local, the problems of today are persistent and global. Continued exposures to toxic chemicals in the environment, global warming, population growth, habitat destruction and social/psychosocial factors have produced crises that require a multidisciplinary research for understanding complex issues. The science and knowledge we bring to the looming environmental crises must evolve to enable prevention/control and protection of public health; the programs in the CEOH seek to expand our knowledge base, provide exceptional training of students to address these issues, and interact with stakeholders. The mission of the CEOH is to take a leadership role in facilitating and promoting research into the biological effects of exposure to environmental agents in order to understand and predict how such exposures affect human health. The trust area of the CEOH is to protect people from toxic pollutants exposure and promotes eco-friendly products and practices that are safe for public health and the environment. To meet these goals, a team of highly experienced and professionally trained personnel are available

Public health policies greatly influence the health of a country. Policies such as tobacco control policy help control cancer cases; transportation policy encourage physical activities; nutrition policies ensure better health so on and so forth. The aim of this centre is to, contribute through research, in the formulation of public health policies that positively influences and enhances the health of the people.

Health promotion and behavioural science draws from biological, environmental, psychological, physical and medical sciences to promote health; prevent disease; prevent disability and premature death through voluntary behaviour change activities that is education-driven. Health promotion helps in development of individual, group, institutional, community and systematic strategies to improve health knowledge, attitude skills and behaviour. The purpose is to positively influence the living and working condition of individuals and communities that influences their health. Health promotion focuses on prevention by which it reduces the costs (both financial and human) that individuals, employers, families, insurance companies, medical facilities, communities, the state and the nation would spend on medical treatment
