UNTIL PROVEN SAFE

A captivating survey of the uses and abuses of quarantines, from the days of the Black Death to the lockdowns of Covid-19.

Journalists Manaugh and Twilley meld a global view of a timely subject with vividly detailed accounts of quarantines, whether of people or hazardous plants, animals, and chemicals such as nuclear waste. The authors show how—since the emergence of “lazarettos,” the quarantine hospitals of medieval Venice and other Adriatic ports—authorities have strived to contain dreaded hazards. Among many others, these have included the bubonic plague, yellow fever, tuberculosis, Ebola, and cholera. Yet some problems resist solutions. “Although the advent of advanced contagion modeling, location tracking, and data mining offer the promise of refining quarantine, rendering it so minimal and precise as to be almost imperceptible,” the authors write, “the use of those tools during COVID-19 has demonstrated that, in many ways, effective quarantine has changed remarkably little since its origins during the Black Death.” Persistent challenges include the tedium of isolation, the architectural rigors of designing suitable facilities, and the xenophobic use of quarantine “to obstruct the passage of undesirable immigrants at the border and stigmatize those who have already arrived.” For such risks, the authors propose fresh, sensible remedies such as a “bill of rights” for the quarantined. But a larger charm of this smart book lies in their ability to bring potentially dry topics to life. They profile the delightfully “obsessive” founder of the Disinfected Mail Study Circle (which tracks epidemics through postal evidence), and, after visiting a greenhouse near London, they note that cacao-plant diseases have contributed to a shrinking global chocolate supply that may lead to a “chocpocalypse.” Chocoholics, beware: One study found that in a decade or so, “a Hershey bar may well be as rare and expensive as caviar.”

An infectiously appealing overview of efforts to contain the potentially infectious.
