Has anyone modeled whether instacart workers doing shopping for a lot of people is actually safer in terms of spread? It’s a near 1:1 substitution but adds a pair of hands. The worker likely has better hygiene but is also more likely to be tired and let down their guard.

Just gives you a chance to decouple - more controlled environment. Porch, Door, Garage, Trunk whatever it is - can keep there and run through disinfection protocol.

Also a factor: fewer individuals in markets if many are ordering delivery. A single worker can serve many households that would otherwise need to send someone to the grocery store.

In the burbs, where everyone has a vehicle, stores offer to shop for you & have an employee deliver the groceries right to your trunk, while you wait in the car with the windows rolled up. Order non-perishables, & let them sit 5 days, and you should be good even if . . .

Being in a supermarket with other people = some infection risk through droplets/aerosol (depends on circumstances) Having someone deliver your groceries without meeting face-to-face = extremely low infection risk, effectively none if you let the stuff sit 1-2 days.

Nonscientific perspective here. If initial viral load has a meaningful effect on subsequent outcomes, seems to me that surface exposure is less of a concern than encountering infected individuals. Also, perhaps easier to mitigate via time decay and disinfection of packaging.

We accept delivery but everything that enters our house gets cleaned or quarantined. So there's at least the potential to dramatically reduce risk overall, even if you assume every delivery person is a carrier
