The virus spreads through droplets. That means that anytime people are together and anyone has Covid that it can spread.
If people continue to mix freely, all those contacts people have incidental to just living their lives means that they can pass it on to those who are vulnerable and will need a hospital bed, even die:
- Older people
- those severely unwell
- people with chronic conditions
- the obese
- the BAME community
- etc etc
Hospital beds fill up and there are only a finite amount. All of a sudden there is no bed for heart attacks, sick children, routine medical needs, car accidents, accidents in general, sepsis, meningitis etc as all the beds are FULL. There are no more, anywhere. All staff maxed out, there are no more, anywhere.
People then die who wouldn't have along with those who die anyway because of Covid. Those extra with Covid, they die too. The more Covid spreads the WORSE the impact on the economy and the longer it lasts. The trick is to suppress the virus to a level where things can function as normally as possible, then keep suppressing it (this means social distancing, all the rules, and more local downs if needed).
Public health policy has to delicately balance 2 things: the economy, protecting people (including saving their lives when needed).
FYI - those countries doing well at managing Covid have populations who are willing to follow the rules for the greater good. They don't riot, they don't complain incessantly. Those people are / will be enjoying fewer restrictions on their lives in the long run. Singapore have been did this and it worked. Smart people... they do as the government says, they want their lives back, they want their families to be safe - it's a no brainer. I work with our office in Singapore and it's embarrassing when they bring up UK media coverage. They feel safe, I don't.
I wouldn't want to make these decisions, but I respect those made. I couldn't live with myself putting someone else's life at risk.
Not sure what this says about Britain. Not a lot I suspect.
Hospital beds are reaching capacity, cases are up significantly and more people are dying. That is why we need a 'circuit breaker'.
It took MONTHS of lock down to suppress the inevitable continued spread arising from that contact which simply can't stop (i.e. critical infrastructure and services).
Ask a different question: Do we really want to leave it its as bad as it was in March?
