Anyone here know this? Does someone working for the Centers for Disease Control (U.S.) have a title such as "agent," or something like that? I even emailed them, but they just said, "You'll have to verify the title with the person or the specific division." Well that doesn't help me much as that person is one of my characters.
They are not called agents. Typically CDC's epidemiologists investigate disease outbreaks. They do have a position they call The Epidemic Intelligence Service Officer (EISO) which is a position for post grad school interns.
Awesome idea! Thanks. That may not tell me how someone would address them when talking to them, but I can certainly use that information in other ways.
An epidemiologist is a "doctor". They may or may not be a medical doctor, but, they almost certainly are a PhD level scientist. So, "Doctor" would almost never be inaccurate or inappropriate to refer to one of the people whose job is to research the epidemiology of an outbreak. Technical field workers, doing things like conducting interviews or collecting samples, from the environment, patients, or cadavers, may or may not be epidemiologists, and they may or may not be medical doctors.
I beg to differ. Many epidemiologists have master's degrees in public health. I assure you they are not just 'technicians'. From the BLS:
