Viral Diseases of Public Health Importance in India: Current Priorities with Special Emphasis on Prevention

Abstract

India faces problems with both communicable and non communicable diseases. The major non communicable diseases are cancer, cardiovascular disease and diabetes mellitus. This article focuses on communicable diseases (infectious diseases) especially viral infections of public health importance. The infections include bacterial, parasitic and viruses. It could be said that fungal infections by the nature of the spread are not of public health concern. The viral infections are transmitted by the respiratory route, water and food borne route, vectors and blood and blood products, sexual route and are of major concern. Efforts are aimed at early detection, prevention by use of vaccines and sentinel surveillance. For the success of public health programmes sentinel surveillance of diseases is mandatory. India has got several programme initiatives addressing the problem. The programs include IDSP, VBDCP and NACO. The approximate cumulative annual prevalence of infectious disease in India ranges from 100 to 200 million individuals affected in one year. India should aim to improve case detection by strengthening laboratory services with manpower training and nationwide quality control scheme, sentinel surveillance activity and prevention by improving the efficiency and scope of UIP. Also, creation of a single portal of infectious disease data handling hub to collect information from different sources will help avoid overlap and duplication of reporting.
