Testing Sewage to Predict COVID-19 Outbreaks
With the onset of the COVID-19 pandemic, Yale researchers Jordan Peccia, SOM’s Edward H. Kaplan, and Saad Omer from Yale’s Institute of Global Health showed that the concentration of COVID-19 RNA in sewage mirrors the spread of the disease through a population.
Now they have found that testing sewage can serve as an early indicator of an outbreak relative to hospitalizations, among other things, and essentially predict COVID-19 outbreaks. The research revealed a worsening crisis three to five days before patients with severe disease require hospitalization.
With over six weeks’ worth of wastewater data, they were also able to get an estimate of the virus’s basic reproduction number – how many other people an infected person would infect giving us a way to predict COVID-19 and hopefully control it better.
