In the Tales Told by Sewage, Public Health and Privacy Collide
From the article
In early March 2020, as Covid-19 cases were accelerating across the globe, the American aircraft carrier U.S.S. Theodore Roosevelt made its way to Da Nang, Vietnam for a scheduled stop to celebrate the 25th anniversary of diplomatic relations between the nations. Nearly 100,000 cases of Covid-19 had been confirmed worldwide, and more than 3,000 people had died from it, when thousands of sailors poured off the ship for five days to mingle with locals, posing shoulder to shoulder for photos, overnighting in local hotels, and shooting hoops with Vietnamese kids.
The tool Daughton was eager to share with the Navy begins at the toilet. He first proposed it 20 years ago: analyzing sewage to see what it says about public health. The field, called wastewater-based epidemiology, began in the early 2000s with researchers isolating the residues of illegal drugs to understand community-wide use. But over the last two decades, wastewater-based epidemiology expanded to look at the remains of other substances, such as pharmaceuticals and alcohol; pathogens, to identify existing and emerging infectious diseases; and substances made in the body that illuminate the overall health of a given population. The research can happen at a single wastewater treatment plant, or scale up to capture information from an estimated three-quarters of the U.S. population and roughly 25 percent of people worldwide.
