Public health officials are trained and experienced in responding to infectious disease outbreaks and life-threatening emergencies. They work closely with scientists and researchers to translate the latest findings into action with the express goal of keeping people as safe and healthy as possible. 

It can be frustrating when guidance changes. It’s the job of public health officials to tell you what they know, when they know it, and guidance regarding COVID-19 has evolved as our understanding of the virus itself has improved and evolved.

Public health officials and scientists are continuing to learn about how the virus spreads, how it affects different people, and how best to control it. As scientists discover new information about COVID-19, public health officials work to provide accurate and timely guidance.
