COVID-19 reaches the island

Puerto Rico's government formed a COVID-19 task force on February 29, 2020: notably, before the island had recorded a single confirmed case. That head start marked everything that followed in the pandemic's first weeks.

On March 12, 2020, a day before Puerto Rico's first confirmed case, Governor Wanda Vázquez Garced declared a state of emergency and activated the Puerto Rico National Guard to help monitor travelers arriving on the island. Acting a day before the first case, rather than in response to it, set Puerto Rico apart from many jurisdictions that waited for confirmed local transmission before moving.

Coverage at the time described Puerto Rico as taking "some of the most dramatic steps of any U.S. jurisdiction" to control the virus: early curfews and business closures that were, at that moment, unusually strict compared with most of the mainland. Some of those same measures were later adopted by mainland cities and states that had initially moved more slowly.

That aggressive early response landed on an island that had barely caught its breath. Hurricane María had struck in 2017, and the earthquake sequence had shaken the southwest only weeks before COVID-19 arrived, in late 2019 and early 2020. Emergency-management systems already stretched by two prior disasters, and a public patience that had already absorbed years of crisis after crisis, were being tested again: this time by a pandemic that, unlike a hurricane or an earthquake, offered no clear end date around which to plan.

There is an argument that repeated disaster built a kind of institutional muscle memory: officials who had spent two years coordinating storm and earthquake response were, by early 2020, practiced at declaring emergencies and mobilizing the National Guard quickly, and that practice may help explain why Puerto Rico moved so fast, even before its first confirmed case, while many mainland jurisdictions were still debating whether to act.
