“We want to move to a situation where at least by the end of May we’re able to substitute some less intensive measures, more based on technology and testing, for the complete lockdown we have now,” Neil Ferguson, a leading professor of mathematical biology at Imperial College London, told BBC Radio.
Britain initially took a restrained approach to the outbreak but Prime Minister Boris Johnson changed tack and imposed stringent social-distancing measures after Ferguson’s modeling showed a quarter of a million people in the country could die.
The response has since been hampered by a lack of ventilators and an inability to carry out mass testing to determine whether the public, and particularly health workers, have built up an immunity.
