exposure, the change in air quality and environment. If someone lives in a high populates area they are more likely to develop asthma, or people who are working in poor environment contribute to lower respiratory symptoms. The change in climate can lend to humans developing allergens. Diarrheal diseases can occur during food preparation in forms of food poisoning and living in waste can lead to gastral diseases.
Ischemic heart disease, cerebrovascular disease, Alzheimer diseases, lung cancer, diabetes, and chronic kidney disease fit into the second transition because people who are dying form these diseases are living longer lives, but are dying from chronic non-communicable diseases.
People who suffer from Ischemic heart disease tend to be smokers, obesity, don’t exercise often and have poor nutrition. This is a fine example of a disease associated with a change at the everyday level. Similar to cerebrovascular disease, Alzheimer diseases which are age associated deaths due to the increase longevity, but are chronic diseases. Diabetes, also fall into this transition because it follows a trend of change in lifestyle of people doing less physical work, but consuming poor nutritional diet heavily seen in developing countries. Also road injury because those are age related deaths
HIV/AID and TB fall into the third transition because they have to do with either the resistance to drugs or it is a new emergence of a disease. Tuberculosis is totally resistant to 1st and 2nd line of drugs. It was first observed in 1980, MDR TB was resistant to two drugs, than in 1993 XDR TB 4 drugs and 2 lines of resistance and the by 2003 TDR TB was when TB was resistant to all 1st and 2nd line of drugs. HIV/AID are new diseases that was first detected in 1983, but was circulating under the radar as late as
1930’s.
