What are the parameters that define each of these states of a diseases effect?Do you agree that bird flu, HIV, or AIDS could be described as a series of epidemics? Why or why not?Should we study epidemiology and disease control as a complement to the provision of healthcare services? Why or why not?Disease control has evolved since the discoveries and achievements of these epidemiological pioneers— Hippocrates, John Snow, Pasteur, and Koch. Explain the impact of at least one major historicalcontribution on the current status of epidemiological practices.
