Middle Murica is full of anecdotal examples.
...and California is full of Quixotic examples.
But I have an anecdotal example to share from California:
I asked a Mexican friend of mine why the coronavirus doesn't seem to be running rampant through the Mexican community. He explained that Mexicans who are not citizens aren't going to hospitals like they normally do because they believe that if they are diagnosed with the virus, they will be deported.
A good friend of mine is an x-ray tech at a local hospital. He says that on any given, normal (pre-virus era) day, the waiting area of the hospital is chock-full of Oaxacan Mexicans. The most common reasons for their visits are stomach aches, foot fungus problems, and advanced, neglected STD's.
Good friend of mine x-ray tech sez that the hospital he works at is far less busy than normal.
