It takes people with many different types of training to combat epidemics. Medical doctors are required to treat the people who have already become infected. Epidemiologists are required to trace the pattern of epidemic spread (is it air-borne, water-borne, food-borne? Does it require close contact or only casual contact? What is the original source of the pathogen? etc...). Lab technicians and molecular biologists are needed to identify the pathogen. Educators are needed to train people at risk in methods of avoiding infection. Engineers are sometimes needed to create methods of purifying water or air to elimiate the source of spread in water-borne or air-borne epidemics. Different skills are needed on the "front line" of a limitted "outbreak" such as an Ebola virus outbreak, than are needed to slow the spread of an existing epidemic such as HIV/AIDS. Different skills are needed to contain an "outbreak" with a known and well-studied pathogen such as mycobacterium tuberculosis or West Nile Encephalitis virus, than are needed to identify a new pathogen, such as the discovery of the "Sin nombre" Hanta virus in the USA in the early 1990s, or the discovery of the Lyme disease spirochete in the 1980s. While the people who travel to the epicenter of new "outbreaks" get more attention in the popular press, it is equally important to work in areas of science or pulic health that aim to prevent such outbreaks from ocurring in the first place, or to put an end to epidemics that have been ongoing for years. Ebola virus has become "hot news" for killing less than 200 people, while malaria and other ongoing pandemics kill millions of people each year. In many cases, the specific pathogen itself, the virus, bacteria or protist, is of less importance overall, than the vectors for spread, such as mosquitoes or contaminated water. I would suggest reading books such as "Virus X" by Frank Ryan, "And the Band Played On" by Randy Shilts, "Betrayal of Trust" and "The Comming Plague" both by Laurie Garrett. These will open you mind to the many different problems and skills needed to solve the problems. Never underestimate the need for political power and public education to aid in the fight. The "front line" people sent into a "hot zone" are most likely to be specific experts in the basic research of the suspected pathogen. If there is an outbreak that seems to be caused by a hemohragic fever virus, experts in the study of that type of virus will likely be sent. If the outbreak seems to be a water-borne bacteria, experts in bacterial sampling will be sent. Blood can be drawn from victims by any local nurse or doctor, to be sent back to a lab for serological work. The less specific your training is to any one type of pathogen, the more likely you would be of use in many different types of outbreaks. For example grief counselors and people trained to deal with prevention of public panic and chaos would be of use in many types of outbreaks.
