The scientific testing techniques and reporting system have been so successful that the CDC is now aiming to expand its efforts to track other pathogens, such as flu viruses and salmonella, in hopes of responding more quickly to future regional outbreaks. (5/5)
At @BiobotAnalytics technicians sift out the viral particles using nanoscale magnetic beads and then run them through a PCR machine—the same device used for the most accurate type of COVID testing. (4/5)
While the idea of turning to poop for data might seem desperate, the process is fairly high-tech: wastewater treatment facilities pump out small samples, which are then shipped to public and private labs for further examination. (3/5)
All you have to do to contribute to the data...is flush. “You're counted, regardless of your access to health care. Regardless of whether you have symptoms, as long as you're using the toilet and that toilet is connected to a wastewater collection system.” (2/5)
With the rise of home testing, health officials lost their tight grip on COVID case tallies. Epidemiologists had a solution—poop snooping. (1/5) 📽️ Here’s how the pandemic made wastewater monitoring mainstream:bit.ly/3xZNPKhU (By@lgroskinn)S
