Although publicity is just one aspect of planning for a health fair, it's arguably the most important. Even the best-planned fair won't be successful if no one knows about it. Contact local companies to see whether someone in their PR or communications area could help you get the message out.
Many companies have internal newsletters which they use to communicate with their employees.
Use community calendars and newsletters to promote the fair. Design fliers and posters that not only inform people about the fair but motivate them to come. Hang fliers or posters in stores, libraries, banks, restaurants, childcare centers, clinics, hospitals, physicians' offices, and churches. Put them anyplace where a lot of people in your target audience might see them. Ask schools to send fliers home with their students.
