Answer:
To Whom It May Concern,
Recently, I've learned a lot about how epidemiologists and organizations like the CDC help to keep populations safe from disease. I’m still in middle school, but I think I might be interested in pursuing public health as a career one day. Do you have any recommendations for how could start preparing for work in a public health field now? Any information you could give me would be great. Thank you.
Sincerely,
George
