How are the people over 70 catching this though?
It’s incredibly contagious. For example studies have shown that covid can survive for at least 28 days on cash, and it’s days on things like glass, plastic, even paper.
It’s killed pretty quickly by UV light, but we get very little day light in the UK in Winter, and when we do, it’s not very bright.
It’s not hard for example to consider a 70 year old, popping to the shop, not going within 2m of anyone, everyone is wearing a mask, but they pick up a bag of pasta off the shelf, that 4 days before someone with covid picked up and decided not to buy, or the shop staff had covid etc, they take it to the till, pay with cash (few over 70s like using cards) get change etc. Their weaker immune system which means they’ll suffer more from covid, is the same thing that means they’re far more likely to not be able to fight off the infection from a simple touch.
It’s staggering really, but for every 100 people with Covid, 80 don’t know they have it, 20 will have symptoms but less than 4 of them will actually self-isolate. 3.4% of people with Covid, actually fully self-isolate.
