Whitty is a practising
National Health Service (NHS) consultant physician at
University College London Hospitals (UCLH) and the
Hospital for Tropical Diseases, and was
Gresham Professor of Physic at
Gresham College, a post dating back to 1597. Until becoming CMO he was Professor of Public and International Health at the
London School of Hygiene & Tropical Medicine (LSHTM) where he was also Director of the Malaria Centre and he remains a visiting professor there. He worked as a physician and researcher into preventing or treating infectious diseases in the UK, Africa and Asia, especially malaria and other parasitic diseases but also other infections of resource-poor settings. In 2008 the
Bill & Melinda Gates Foundation awarded the LSHTM £31 million for
malaria research in Africa. At the time, Whitty was the principal investigator for the ACT Consortium, which conducted the research programme.
Government roles From 2009 to 2015, Whitty was Chief Scientific Adviser and director of research for the
Department for International Development (DFID). He led the Research and Evidence Division, which worked on health, agriculture, climate change, energy, infrastructure, economic and governance research. During this time, with co-authors
Neil Ferguson and
Jeremy Farrar, he wrote an article in
Nature titled "Infectious disease: Tough choices to reduce Ebola transmission", explaining the UK government's response to
Ebola in support of the government of Sierra Leone, which he took a leading role in designing, including the proposal to build and support centres where people could self-isolate voluntarily if they suspected that they could have the disease. From January 2016 to August 2021, Whitty was Chief Scientific Adviser to the
Department of Health and Social Care, responsible for the department's research and development work, including being Head of the
National Institute for Health and Care Research (NIHR). This included appearing – often with prime minister
Boris Johnson and
Chief Scientific Adviser Sir
Patrick Vallance – in televised news conferences, and giving evidence to parliamentary bodies. From 19 March 2020, Whitty appeared in
public information adverts on national television, explaining the government's
social-distancing strategy to reduce the spread of the virus during the pandemic. On 27 March, Whitty was reported to be self-isolating owing to symptoms consistent with
COVID-19 after
Boris Johnson and
Health Secretary Matt Hancock had tested positive for the virus. On 6 April, he had reportedly returned to work having recovered from the symptoms of the virus. In July, he told the Lords
Science and Technology Committee that elimination of the disease in the UK would be very difficult, a view that was contested by other scientists including members of the
Independent SAGE group. At a televised briefing on 12 October where the Prime Minister introduced
three tiers of localised restrictions, Whitty said he was "not confident" that the measures in the highest tier would be "enough to get on top of it". Whitty and Vallance presented updated data and forecasts at a televised briefing on 31 October, where the Prime Minister announced stricter measures for the whole of England. During the outbreak,
BBC health editor
Hugh Pym called him "the official who will probably have the greatest impact on our everyday lives of any individual policymaker in modern times". During the Christmas weekend of 2020, Whitty was spotted treating coronavirus patients in London. It was said he "worked the shifts in his capacity as a practising doctor [as] a consultant physician at University College London Hospitals Trust... on the north London hospital's COVID-19 ward over the weekend and bank holiday Monday". On 26 June 2021 a group of
COVID-19 protesters demonstrated outside what appeared to be Whitty's flat in central London. Whitty was subject to other harassment. The Health Secretary,
Sajid Javid, said that those responsible "should be ashamed". The Vaccines Minister,
Nadhim Zahawi, said they were "thugs" and should face charges. ==Awards and honours==
