The
public health field is broad and diverse, bringing together experts with very
different backgrounds and perspectives. Through close collaboration, healthcare
researchers, public health professionals, government officials, community
stakeholders, and others seek to mitigate the impact of health problems, from
heart disease and diabetes to infectious diseases and environmental hazards. In
this regard, National programs at Health protection Agency (HPA) focuses on
creating awareness, developing guidelines and surveillance of public health
areas.
