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
Evolution of Infectious Disease The way a host lives contributes heavily to how their body will react to pathogens. If an organism lives a moderately healthy lifestyle, including their diet, physical activity, and has a decreased amount of stress to deal with, their chances of fighting off infectious diseases increases. Host resistance pivots around how well a host’s immune system can fight off a disease and rid their body of the pathogens. Although a healthy lifestyle can help a host, infectious diseases seem to evolve so quickly that a new generation of a disease may have emerged before scientists have the chance to make
