Covid 19 virus

This theory might not be applicable to this virus. There is evidence that COVID-19 can spread asymptomatic (before the host starts showing symptoms or dies).
As for expectations that the virus will become less potent with hotter weather and higher humidity... That did not work well in tropical hot Singapore, Malaysia, Indonesia, Thailand, in warm Hong Kong, California, or in countries of Southern Hemisphere, including Australia.

We went shopping here yesterday and except for hand wipes and TP we didn't have any problems getting what we wanted. The store was busy but no worse than when all of the local university students come back from any of their breaks. We had to stand in line for perhaps 30 seconds to get to the check out counter but that was it.
Since the theme parks and the schools closed there are a lot of people out and about, mostly out jogging, walking their dogs, or working on projects around their houses. I just came back from going out and buying another Oxy/Acetylene torch with tanks. I'm going back to buy a MIG welder and two tanks tomorrow. Life is good, at the moment!

Here while we have pretty strong measures in place (no gatherings >50 people, schools, cinemas etc closed etc) at the shop it's a day like any other.

We just got a message from my BIL in Barcelona, he said that yesterday that everyone was out on the streets and having a good time and everything was open but it's a different story today. The streets are empty and almost everything is closed. They did find a couple of snack shops that are open but with no eat in. Everything is strickly take out.

That is a big question whether UK's approach is good or bad, however.
Europe does following - they try to slow down the rate of spreading, they do not attempt to stop the virus, as it is not possible, it seems.
By slowing down the rate they want to de-load their national health systems (to avoid the overloaded Italy scenario).
The experts know already the XX% of the population will certainly acquire the virus this year. The Chinese and other statistics show ~80% of cases are with none or mild symptoms. With sufficient treatment of the difficult cases, under "normally" working hospital care, they can master it without more fatalities than with flu. That is what UK and Germany (and others) are targeting, imho.

That's not a theory, that's how life usually works.
AFAIK COVID-19 spread so much not because of the long spreading time before evident symptoms, but because many people did not have any noticeable symptoms or just thought they got ordinary flue.

That's because in those countries, even decades ago when I spent a few years there, air conditioned is widely spread and it offers the ideal conditions for the virus survival and spread (cold and dry air).
