Please provide me with suggestions and ideas for the following questions:
1. What theories about the causes of disease have persisted from early times until today? Do you think that any of the basic principles of disease occurrence are interrelated? Explain. Reference your response.
2. What were the major "breakthroughs" that contributed to a more scientific understanding of disease causation? Reference your response.
3. Are there any measures for disease prevention which were used in early times that should/could be used today? Why do you think some were discarded as preventive measures? Reference your response.
