I am very mindful of the Director-General of Health—in fact, the World Health Organization was itself somewhat slow, I think, to declare an international emergency. But he's got it, because his advice at his press conference yesterday was simply this: "This is a serious disease. Although the evidence we have suggests that those over 60 are at highest risk, young people, including children, have died." And his advice? "Once again, our key message is: test, test, test." I have been calling for weeks for a more liberal approach to the testing regime, because it's only when we know who are the cases who have the virus, who could be at risk of spreading it, can we control this outbreak.
