-3 epidemiological transitions

3rd Epidemiological Transition-emerging diseases and human activity
Dams schistosomiasis

Cultivation hemorrhagic fever
-general term for a disease that causes really high fevers and cause internal and external bleeding

Irrigation mosquito borne diseases
-when we feed plants with water-standing water is where mosquitoes lay their eggs

-animal husbandry practice has created an environment for influenza virus to mutate
These are human activities that benefit but there are unintended consequences/diseases

-restricted mainly to central Africa
-when virus gets into the body it causes extreme fever and internal/external hemorrhaging
-organs start to bleed out
-no treatment or vaccine
-50-90% mortality-when we look at this rate around 50% but can get as high as 90%, especially in
developing nations in Africa
-Ebola is transmitted through direct contact with blood or other secretions
Biological and Social Landscape of Ebola
-natural host are bats
-however if they come into contact with other animals specifically apes, chimpanzees and a small
