The Centers for Disease Control and Prevention (CDC) has estimated that SARS-CoV-2 entered the United States in late January or early February 2020, establishing low-level community spread before being noticed. [8]  Since that time, the United States has experienced widespread infections, with over 33.4 million reported cases and over 600,000 deaths reported as of June 25, 2021.

On April 3, 2020, the CDC issued a recommendation that the general public, even those without symptoms, should begin wearing face coverings in public settings where social-distancing measures are difficult to maintain to abate the spread of COVID-19. [9]

The CDC had postulated that this situation could result in large numbers of patients requiring medical care concurrently, resulting in overloaded public health and healthcare systems and, potentially, elevated rates of hospitalizations and deaths. The CDC advised that nonpharmaceutical interventions (NPIs) are the most important response strategy for delaying viral spread and reducing disease impact. Unfortunately, these concerns have been proven accurate. 

The feasibility and implications suppression and mitigation strategies have been rigorously analyzed and are being encouraged or enforced by many governments to slow or halt viral transmission. Population-wide social distancing plus other interventions (eg, home self-isolation, school and business closures) are strongly advised. These policies may be required for long periods to avoid rebound viral transmission. [10]  As the United States is experiencing another surge of COVID-19 infections, the CDC has intensified their recommendations for transmission mitigation. They have recommended universal face mask use, physical distancing, avoiding nonessential indoor spaces, postponing travel, enhanced ventilation, and hand hygiene. [11]
