I understand CP can be nasty but I don't see any point in the quarantine advice. The virus is infectious for two days before the spots appear and obviously nobody knows it's coming so the virus is spread. Then the spots arrive and you have five days of house bound hell despite the fact you have already exposed people for days before.
And if the NHS were really concerned about stopping CP spreading they would vaccinate, but they don't. In fact they rely on kids getting CP young as it's more serious when old.
So can anyone explain the point of quarantine given you will already have exposed others to the virus? Isn't it rather a case of shutting the stable door after the horse has bolted?
