Stage I: Stage of pestilence and famine Stage I: Stage of pestilence and famine. Infectious and parasitic diseases were primary causes of death and kept human population in check during stage I of DTM. (i.e. Black Plague, typhus, cholera, small pox.) Stage 2: Stage of receding pandemics. Pandemics receded due to improved sanitation, medicine, and nutrition diseases. BUT: cholera spread quickly as poor people crowd into rapidly growing industrial cities. Stages 3: Stage of degenerative diseases. As people live longer and vaccinations virtually eliminate infectious disease, people now die of chronic diseases associated with aging (heart disease, cancer, etc.) Stage 4: Stage of delayed degenerative diseases. New medicines and technologies extend the lives of those with degenerative diseases (statin drugs, heart surgeries, chemotherapy, etc.) Stage 5: Stage of reemergence of infectious diseases. Infectious diseases reemerge as they adapt and become immune to the antibiotics that have been used to control them
