One of the cities close to my hometown is on there. There are two major hospitals plus a private hospital, which are the major employers in that city. After that major employers are factories and several large supermarkets. There are hundreds of care homes surrounding the city for everything from the elderly to children with disabilities and rehab units and supported housing. There’s a huge Christian and Muslim Community and the places of worship, of which there are several dozen, are still open for public services. The University and College courses for Medicine, Nursing, Dentistry, Pharmacy and Teaching are going ahead as normal. Goes without saying with so many employed as key workers in the area, most of the kids are still in school. Many multi generational households too where you might have adult children who are doctors, nurses, pharmacists and teachers all living in the same house as parents and grandparents. Plus lots of students in private student accommodation. Many people commute by train and bus.
The vast majority of people in that city ARE abiding by the rules but by its very nature it’s never going to get down to zero transmission.
I can think of the road that one of the major hospitals lies on. Directly opposite is a supermarket, a coffee shop in the supermarket plus a Costa, a Greggs, a Subway, a Pharmacy, a school and two churches. You always see people in the supermarket in uniform from the hospital and I’ve often been in the church (pre Covid) alongside medical staff straight off a shift who go there for peace and reflection. The coffee shops are all open for takeout and are always busy with both staff, patients and their relatives, as is the supermarket. Parents who work at the hospital take their kids into the supermarket straight after or before school. The rest of the houses are mainly bungalows or dormers on quiet estates so lots of elderly people living there who are also in and out of the supermarket. It’s no wonder that it’s an area of high infection rates. It’s just the demographic.
