When the coronavirus first struck the U.S. in March, every state implemented restrictions aimed at limiting its spread. Businesses closed, schools and offices went remote and much of the country was under strict orders to stay home — at least temporarily.

By mid-May, all 50 states had begun the process of easing restrictions, seeking a balance between reopening economies and protecting public health. Some took statewide approaches, some used regional frameworks and some reopened faster than others. Health experts warned that many states and localities were moving too quickly to do so safely.

Coronavirus cases soon began to skyrocket in much of the country, particularly in the South and West. States including Florida, Texas, Arizona and California reported unprecedented spikes in new cases and hospitalizations.

As of early August, the country has surpassed 4.8 million infections and recorded nearly 160,000 deaths, leading the rest of the world. And unlike earlier this spring, cases are widespread in rural as well as metro areas, marking what White House coronavirus response coordinator Dr. Deborah Birx called a " new phase" of the epidemic in the U.S.

Many states are pausing their reopening plans, reintroducing restrictions and tightening mitigation measures. Some are shutting down bars and delaying the opening of indoor dining. More than half have introduced statewide face covering requirements.

With the impending start of the academic year, state and local leaders are grappling with how to safely reopen their schools. Governors are also announcing ever-evolving testing and contact tracing initiatives, economic relief programs and travel restrictions.
