A freelance health writer creates health and wellness-related content for blogs, websites, and other publications. As a freelancer, you can work with several different clients on a contract basis, and your duties vary from client to client. Your responsibilities often include researching a medical or wellness topic, interviewing experts, and gathering other background information before you write the article and prepare it for publication. You may also report on healthcare news or work with medical professionals to create pieces for a scholarly journal. Health writers can also create content for marketing, public outreach, or healthcare education campaigns.
