The nos of black and Hispanic people in the USA dying are higher but are down to the nos living in poorer areas, crowded buildings and the systemic problems due to work with low income and racism. Next add in the systemic problems due to low income and lack of employment, medical insurance and lack of and underfunding in poorer areas, I. E they would not get an ambulance or sometimes even fire service to attend, let alone a hospital that will admit them.
Free and low income clinics have closed under Trump compounding the problem. People are literally turned away from hospitals.
Yes this happens to low income white Americans but disproportionately more to Black and Hispanic Americans due to institutional and systemic racism leading to lower income, lower quality housing, etc
In the UK, a lot of ethnic minorities do live in larger family groups and work in more front line areas. The thing I see is also a reticence to seek help. So even when ill, they may delay going to the Dr. The other side of the coin is when going the dr, quite often being dismissed (like a lot of women it seems).
But I do think the UKs nos in general are due to low hygiene practices (amazing the amount of people who routinely did not wash their hands), lots of public places Incl buses and train being filthy, slow and poor government response with wishy washy advice for weeks until lock down. Underfunding for a decade of the NHS and austerity cuts in the ancillary services of social services, social care, community health, community mental health, mental health generally, disability services etc, school nurses, children's centres and on and on, which all affect costs within the NHS and cause more money to have be spent in the long run. Ie the cuts work out more expensive than not having had the cuts in the first place.
Add in the exceptionalist attitude of lots of brits who even back in mid to late March thought covid-19 and WHO advice did not apply to the UK.
HOWEVER
Each country has their own problems due to their own culture ie Italians, smoking, family household group and a stubbornness to adhere government advice.
What is interesting is why countries very similar culturally, like Spain and Portugal would have such different nos in positives tests and deaths.
Also interesting to see, is how quickly New Zealand, majority of African and Caribbean countries and some South American countries locked down and it will be interesting to see their nos in the coming weeks. Lock down and testing seems to be the most useful things, so it will be good to see if it's as beneficial especially in countries that locked down quickly ie some with very low and even no deaths at the point of lockdown.
In contrast it will be interesting to see what impact those countries with anti lock down and a disbelief in Corona will see, Ie Brazil, Belarus and Turkmenistan to name a few, where their governments are telling people to carry on as normal.
Corona virus response will be written apart and studied for years to come.
