Coronavirus: Prince Charles out of virus self-isolation

The BBC news reports that ‘Prince Charles out of virus self-isolation’ [LINK].

Prince Charles had been tested positive and showed signs of the virus. So did he have it, and if he did not, does this mean these tests are pointless that all the nurses and doctors are demanding?

If Prince Charles did have it. Who is aged 71. Does this show that even someone aged 71 is at no real risk, and you can recover extremely quickly?

Have we honestly shut the country down, destroyed the economy, and sacrificed many lives (people who should be going to the doctors for illnesses such as cancer), for something that seems to be less deadly than the common cold, simply because the public demanded it, on the back of some rather hyped up doctors and nurses, who seem to have pumped fear into the population.
