After the end of the Second World War, Sir McFarland Burnett confirmed that most challenges with infectious diseases were solved. Worldwide history is intertwined with infectious diseases with the effects that infectious diseases had on the human population. Evidence of smallpox was found in an Egyptian mummy which was 3000 years old (Anderson & May, 2015). Researchers wrote about the spread of infectious diseases through air and water. The development of a microscope led to the discovery of micro-organisms and vaccines that would later be used to control and prevent diseases. The 20th century came with the invention of antibiotics and chemotherapy of infectious diseases. Dependence on vaccination programs increased with the aim of preventing infectious diseases (Hethcote, 2014).
