Authorities have imposed international travel restrictions from late February 2020 – one month after the first cases were detected in the country – and nationwide social distancing guidelines from late March 2020. The country has the highest case and fatality figures in the world. From March 2020, stay-at-home lockdown began to be implemented as the virus spread across the country. All states began reopening as of June 2020 at widely varying paces, before reimposing restrictions from October 2020, and then moving once more to lift most remaining measures as of April 2021 while implementing vaccination campaigns. Approximately 100,000 cases per day were reported nationwide as of May.

American, United, Delta, Southwest, JetBlue, Allegiant, Hawaiian and Alaska Airlines have suspended hundreds of domestic flights due to COVID-19-related staff shortages.
The Centers for Disease Control (CDC) announced that domestic travellers who are fully vaccinated against COVID-19, defined as two weeks having passed since obtaining their final dose of the vaccine, do not need to get tested before or after travel and do not need to self-quarantine. Domestic travellers are recommended to take a viral test 1-3 days before departure and to self-quarantine for 7 days upon arrival. Travellers should get tested again 3-5 days after arrival; if a test is not available or results are delayed, travellers should self-quarantine for a total of 10 days.
In areas where COVID-19 hospitalisations are high, non-urgent surgeries will be suspended and ambulance services will not be dispatched for non-life threatening emergencies. Long wait times are certain due to staff shortages at public and private healthcare providers nationwide.
