"When the term civics is used in the context of education, most students and teachers in the United States think about the process of learning about the Constitution, the Bill of Rights, co-equal branches of the federal government, and the relationship of state governments to the larger functioning of the nation. Often, however, the approach to civics is less than applied, and the lessons may come across as irrelevant to students. It frequently is not apparent that governments - at all levels - are very much involved in one aspect of our daily lives: promoting and protecting the health of the public. With the year 2020 ushering a global pandemic into the lives of Americans, the term public health quickly became used in everyday language, the media, and the offices and meeting rooms of state and federal elected representatives. For most Americans, this was the first time in their lives that public health was not taken for granted"-- Provided by publisher.
