Primary Care Epidemiology
Primary care epidemiology can add to more extensive changes in health and healthcare services, through better comprehension of disease aetiology, use of healthcare services and the role of different healthcare interventions. Primary care is conveyed by an extensive range of health professionals, nurses, doctors, care assistants, mental health specialists, dieticians, pharmacists, dentists, optometrists and other health care professionals. Emerging Infectious Diseases are a proceeding danger everyone. Some diseases have been viably controlled with the help of modern technology. Yet new diseases—such as SARS and West Nile virus infection are constantly appearing. Others, such as malaria, tuberculosis, and bacterial pneumonias, are now appearing in forms that are resistant to drug treatments. Age-related physiological impairment and disease are known to be subject to environmental influences, and there is increasing evidence that they have a significant genetic component.
