Everyone knows that health communication and marketing can raise awareness about health issues and promote prevention behaviors. But did you know that health communication and social media marketing plays a critical role in responding to outbreaks? Right now, CDC is participating in a unique, interagency collaboration with the U.S. Department of Health and Human Services (HHS) and the Food and Drug Administration (FDA) to use interactive and social media to enhance the response to the recent Salmonella Typhimurium outbreak and its associated recall of peanut butter and peanut-containing products. Many of my colleagues in the National Center for Health Marketing are working closely with scientists and communicators in the National Center for Zoonotic, Vector-Borne, and Enteric Diseases (NCZVED), including people in NCHM’s Division of eHealth Marketing and the Emergency Risk Communication Branch in the Division of Health Communication and Marketing.
