Speaking this morning, Andy Burnham, the Health Secretary, and Sir Liam Donaldson, the Chief Medical Officer, said that there were hotspots where swabbing and lab confirmations of the virus now put an unjustifiable strain on time and resources. These areas, including the West Midlands and London, are now shifting from the containment phase, which is led by the Health Protection Agency, to outbreak management, led by the strategic health authorities and local health trusts.
