Evolution of Infectious Disease infectious disease can be induced by bacteria, viruses, fungi, and parasites. Several examples of infectious diseases are as follows: tuberculosis, chickenpox, mumps, meningitis, measles, and malaria. Infectious diseases can be obtained through many routes of transmission such as inhalation, open wounds, sores, ingestion, sexual intercourse, and insect bites. Author, Paul Ewald used his book to expound upon infectious diseases in humans and animals, explain various routes of transmission as well as epidemiology as a whole. Epidemiology is defined as the study of the onset, distribution, and control of diseases. Evolutionary epidemiology focuses on the distribution of infectious diseases whereas Darwinian
