Farewell, Public Health England. Hello, National Institute for Health Protection. As expected, the hammer has fallen on the agency that promised to ‘protect the public’s health from infectious diseases’ but floundered hopelessly when tested by coronavirus. PHE failed to expand diagnostic testing, failed to engage with the private sector, stopped contact tracing when the virus was just getting going, discouraged the use of face masks, refused to share infection data with local authorities and couldn’t even count the number of people who died of Covid-19 properly.
