There are many different sectors of medical research. Some focus on a certain disease while others try to predict what is coming in the future. If you're attempting to study the spread of diseases and health patterns in general than you might turn to epidemiology. This is the study of health based on population statistics. It determines the difference between those living in luxury homes in North America and those residing in rural India and how those factors are going to help determine their health.
We are learning more and more that the environment is a huge influence on personal health. There are some obvious cases, like with people working in mines having a larger chance of contracting some lung-based diseases, but there are also less obvious things. There are many people doing research to see if someone living in homes on the East Coase has any health markers that are common with others in their area and any difference from people in other sections of the world.
In the past few years we have heard more about preventing the spread of diseases and keeping outbreaks contained to a smaller radius. Thanks to all of the international travel that happens these days, it's more difficult to track where contagious diseases are starting and the rate that they might spread. Researchers obviously cannot wait until a disease starts spreading from Ontario farmers to households in Tokyo to think of some way to contain it so they try to stay on top of things by tracking an illness when it's affecting much less people in a smaller area and containing it right there.
If you're considering living in a small town you will likely not find too many differences when it comes to area factors that will affect medical research. You will usually need to be looking at a much larger area to come to any different conclusions. If you're thinking of moving from one side of the country to another, maybe Vancouver to Halifax, than you might want to check on the environmental factors that might affect your overall health.
Area research for health can be one of the most helpful things in determining the spread of diseases. Not only can they look at what illnesses are likely to go through different areas in time to help prevent a wider spread of that issue, but they can also help to make changes in areas where the environmental factors can be eliminated or reduced. If you're looking for a specialist for your medical research than you might want to consider the difference that you could make by entering the epidemiology sector. This involves working with bioresearch and even doing active studies with human participants who are currently dealing with certain diseases or symptoms. You may even find scientists who are working closely with dental clinics just like Dental Studio in London to determine if poor water quality has long term effects on gum health.
