Life science studies life in all its forms including past and present. Epidemiology is a branch of life science that looks at the life cycles of disease. It is the method used to find the causes of health outcomes and diseases in populations. It may seem strange to think of something like the flu as alive but these diseases are made of tiny living organisms. Epidemiology looks at how they live, how they reproduce, how they affect humans, and how they die. It is the cornerstone of public health looking at outbreak patterns of diseases, coming up with treatments and cures, and developing vaccines against them. Epidemiological research helps us to understand how many people have a disease, if those numbers are changing, and how the disorder affects our society and our economy. The epidemiology of human communication is a rewarding and challenging field. Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, bio monitoring, and comparisons of treatment effects such as in clinical trials.
