She has played pivotal roles in the UK's Covid-19 response, serving as incident director at Public Health England, interim chief medical advisor to NHS Test and Trace, and strategic response director during the pandemic. She served as chief medical advisor at UKHSA from November 2021.

Health and social care secretary Wes Streeting said: ‘Professor Hopkins brings extensive experience in the field of infectious diseases and public health as well as significant leadership skills and knowledge of the agency.

‘This new appointment is a key element to protecting our nation's health, including monitoring disease outbreaks, providing scientific expertise to inform policymaking and preparing the UK to fight emerging health threats.'

Chief Medical Officer Professor Chris Whitty said: ‘Professor Hopkins has consistently provided outstanding leadership and expertise throughout a number of major public health challenges, including Covid-19 and Mpox.

‘Her considerable experience and technical knowledge will be invaluable in the role of UKHSA chief executive.'

Professor Hopkins' leadership will prove critical to UKHSA as it navigates the next period of health security challenges, as set out in its recent strategic plan. This includes vital work to prepare the nation for future health emergencies and to strengthen the UK's overall ability to respond to potential crises. 

Prof Hopkins said: ‘I step into this role with humility, excitement, and deep commitment to our mission - protecting people's health and security, quietly, consistently, and expertly.

‘I'm incredibly proud of the work UKHSA does and of the world-class expertise we have right across the agency. My priorities are ensuring we continue to deliver excellence in health protection and security and strengthening our capabilities and systems to enhance how we support our communities.'
