Wastewater monitoring has been used for decades to assess the success of va ccination campaigns against poliovirus, says Charles Gerba, an environmenta l microbiologist at The University of Arizona in Tucson. The approach could also be used to measure the effectiveness of interventions such as social distancing, says Gerba, who has found traces of SARS-CoV-2 in raw sewage in Tucson.

Sounds good. It's going to take horribly sensitive assays, and there may be problems working out how much of the biological waste in the wastewater is of human origin, but it would be a direct and relatively rapid measure of the actual rate of virus shedding in a local population.

They need to gather as much data as they can right now. This is exactly the kind of application AI is good for.
Sounds like it would be prudent to stop drinking raw sewage for a while, until this thing is over.
There is a 3-hour tour of the main sewage treatment plant here in San Francisco. Mo got us reservations as a birthday present for me. It was really cool. The plant is just a bit northwest of Lash Lighter Basin.
I designed the engine and boiler controls for the Lash ships when I was still in college. It was the first PID I'd ever done, at 32,000 horespower. I used a nonlinear breakpoint thing to get the steam valve position close open-loop, and then applied a PID limited-range RPM feedback. That way, a bad tach or something wouldn't produce a dangerously large runaway.
I simulated that on an HP9100 programmable calculator, and then a PDP-8 and graphed the step responses on a Teletype.

Is AI real? It sounds like the same bunch of guys hacking code under a new buzzword.
How would it help here?

John Larkin misses the point completely.
It's a technique for mononitoring the spread of the disease.

Amongst other things it would pick up virus being spread by people who had such a mild case of Covid-19 that they never got tested for infection or co unted as infected.
You think that they are lots of them (despite having zero evidence about ho w numerous they actually are, and ignoring the evidence that suggest that t here can't be all that many of them).

It's VERY real, and given too much autonomy in applications.
Looks like this "deep learning" is the most applicable part. It can inform an adaptable data collection and analysis measurement system that otherwise would be infeasible due to expense, or impossibility, such as getting ever yone to volunteer to be tested, or attempting to geographically localize th e data with greater precision.
