The CDC Public Health Matters Blog is a forum where health professionals can share their public health passions about the evolution of public health and the continual strides that are being made to protect and save lives through education, awareness, research, and promoting healthy lifestyles.  Contributors include scientists and other subject matter experts who spend their days working with some of the most critical infectious diseases, as well as preparing for and responding to public health emergencies that threaten us in the United States and around the world.  From high-tech labs in Atlanta to the field worldwide, please join us as we share our perspective and personal experiences working on the front lines of emerging infectious diseases and public health emergencies.
