Britain must begin its recovery – before more damage is done
The discovery in Britain that a £5 steroid, dexamethasone, can be effective in treating Covid marks a potential breakthrough in our understanding of the virus. Much remains to be learned about the wider potential of the drug but the claims made about its success are striking: that it reduces deaths by a third in patients on ventilators and by a fifth in patients receiving oxygen only. It has not been shown to benefit Covid patients who do not require oxygen. But this can still, in a global pandemic, mean thousands of lives saved. There are two further points to be made. With Covid-19, there is a better chance of finding a treatment for the virus than of finding a vaccine.
