Infectious diseases fall under the category of communicable diseases and are clinically evident diseases that result from pathogenic biological agents that infect a single host organism. Some infectious diseases are also termed as ‘contagious’ when they are transmitted through contact with a medically sick individual. Contagious diseases are easily transmitted and they are highly infective in nature. An overwhelmingly vast majority of the Indian population is afflicted by a range of infectious diseases that include tuberculosis, malaria and HIV-AIDS.
