What are the best datasets for the efficacy of various methods (social distancing, custom masks, n95 masks, etc...) for preventing infection?

Just looking to apply my deep learning capabilities against quality datasets to learn how the combination of certain measures curb, slow, or otherwise, prevent infection. I’m thinking things like population density, social distancing measures, using custom masks, using n95 masks, wearing gloves, and any other socio/economic data.

If this has been discussed elsewhere please just point the way.

Thanks much!
