Infectious Diseases: Control and Prevention

Multi Pathogen Infections

Diagnostic Pathology requires with examination of body tissues and their examination, Microscopical study of disease determination, abnormal tissue development, histopathology of lesions and sometimes post-mortem. It does research on critical diagnosis in surgical pathology. Many diseases are associated with bacterial infections. A pathogen predisposes to diseases states but may not cause disease. It may cause disease only in combinations (toxins exposure).Any disease causing gene that reduces survival and reproduction will eliminate itself over a number of generations therefore genetic diseases are self-extinguishing. For example, genes that encode sickle cell anaemia are maintained and persist down generations, as these genes protect against malaria, which kills millions worldwide every year. About 70% deaths in US results from chronic diseases and the treatment accounting 75% of all US healthcare costs (amounting to $ 1.7 trillion in 2009).
