NY new cases were people staying at home

Wow, not good news.

I thought handling mail or delivered groceries not disinfected not washing hands promptly but 66% 

Most apartment buildings have a vent in the kitchen and bathroom to draw out air, most likely the door is not airtight and is drawing air from the hall. Don’t know what type of abode if tomorrows # are similar we got a real problem....sigh

I can't speak of the improperly vented pipes.  Buildings here range from 100plus years old to new builds to private homes, attached homes, brownstones, etc...  It's possible, but it really depends on where these new infections are taking place.  Different sections have different builds depending on the popularity or gentrification of the neighborhood.  The general assumption is that all of NYC is like Manhattan.  It isn't.  The vast majority of residents are in the outer boroughs which aren't at all like Manhattan and are more suburban/urban rather than urban.  For example, where I am the last new residential build was erected sometime in the early 1980's.  Before that, who knows?  

What I can add is my experience. It is nigh on impossible to get a grocery delivery slot in the last couple of months. Even when one does, a cart loaded to $200 or so to try to stock up for a few weeks, is decimated by "out of stock". This forces people out to the grocery which I'm sure people believe the big box and supermarkets are the best place to find what they need. I find it is more likely that I will find what I need in the smaller privately owned neighborhood groceries or bodegas (corner store). Then there's the Food Stamps (SNAP) issue. There is one grocery service in this region that can accept SNAP online. Otherwise retirees and elderly on fixed incomes must go to the grocer to use them.

Then there's those who don't consider younger members who are out and about as being infectious. This last bit is what I think is a big factor. Even before the groceries issue. Being that my "knitting chair" is situated so I can look out the window (and where I spend most of my time lately), I've noticed that it is mostly young people in their late teens, 20's and early 30's who seem to not think masks are necessary. A good 50%. Then there's the occasional older couple walking past where she is wearing a mask, but it must be unmanly for her partner.

Then there are the food pantry lines. I've read and seen news reports that they can be blocks long with little or no enforcement of social distancing and some without masks. The latest from the head of the police union thinks that Police should not be doing this kind of enforcement, which IMHO is a slippery slope for another conversation.

Lastly there is a NYC priority to keep elderly and disabled in their own homes as long as possible. This program includes heavy usage of home healthcare aids. Not to label, but these healthcare aids are generally minorities, foreign, poorly educated and poorly paid .  They generally use mass transit to travel to their charges.  And of course the issue of home healthcare companies failing to give aids proper PPE to keep them and their patients safe.  To my mind, this is without doubt a good part of the reason. Look at the nursing home issue.

So although very disconcerting to me personally, being over 50, it doesn't surprise me very much that the highest rate of the new infections are people over 50.
