We need to continue with the lock down until we have some form of treatment. There are a number of trials ongoing as we speak the results of which will be released over the coming months.
Testing to identify those who have, and have had, the virus is imperative, we need to get into millions of tested before we can think about relaxing the lock down.
We could see as a result of the tests those who have had it go back to work and shops opening to only those who have had it. This move would be divisive but would allow the economy to restart.
