COVID-19 was downgraded by the UK Government on 19 March 2020 because it was deemed to be better understood, testing was available, and clinical awareness had risen.

COVID-19 was first classified as a High-Consequence Infectious Disease (HCID) in the UK on 16 January 2020, when it was referred to as the “Wuhan novel coronavirus WN-CoV”. It was then downgraded from HCID status by the UK government on 19 March 2020.

However, important context is missing from this simple-sounding statement.
In the UK, an HCID is defined according to the following criteria:

  • acute infectious disease;
  • typically has a high case-fatality rate;
  • may not have effective prophylaxis or treatment;
  • often difficult to recognise and detect rapidly;
  • ability to spread in the community and within healthcare settings; and 
  • requires an enhanced individual, population and system response to ensure it is managed effectively, efficiently and safely. 

The UK government explained: 

“Now that more is known about COVID-19, the public health bodies in the UK have reviewed the most up to date information about COVID-19 against the UK HCID criteria. They have determined that several features have now changed; in particular, more information is available about mortality rates (low overall), and there is now greater clinical awareness and a specific and sensitive laboratory test, the availability of which continues to increase.”

The government also stated that cases of COVID-19 were no longer only managed by high consequence infectious disease treatment centres.
