Epidemiologists are scientists who study populations societies and cultures with regard to patterns of disease or health risks the overall initial goal being to predict the occurrence of disease accidents or in some cases behaviors (for example smoking or reproduction at early or late ages) that can result in health risks. The ultimate goal of the research they conduct is to develop strategies to control and even lower the probability of anything that has a negative impact on public health. The website www.wisegeek.com says that epidemiologists must have bachelor’s degrees in some type of science but most have graduate degrees (Master’s or Ph.D.) in public health or epidemiology. Graduate programs leading to a career in epidemiology include courses in biochemistry toxicology biostatistics psychology and health services administration. Epidemiologists need a firm background in statistics and probability so that they can design studies and both analyze and interpret data that are collected on the occurrence of accidents diseases reproductive habits and so on. Many epidemiologists specialize in specific topics such as the occurrence of cancer pandemics and reproduction and a majority of epidemiologists work for governmental agencies such as the World Health Organization (WHO) or Centers for Disease Control (CDC). The reports that epidemiologists produce are often influential in determining health policies. Others work at universities or private research labs but some serve as consultants to both public and private agencies. The website www.encyclopedia.com states that entry level salaries for epidemiologists are approximately $40000. However those with some experience and a graduate degree can earn over $100000.
