Sunetra Gupta (born 15 March 1965[2]) is an Indian-born British infectious disease epidemiologist and a professor of theoretical epidemiology at the Department of Zoology, University of Oxford.

[11] In July 2013, Gupta's portrait was on display during the prestigious Royal Society's Summer Science Exhibition along with leading female scientist such as Madame Curie.

"[15][16] A one in ten thousand infection fatality rate (IFR) was impossible for the spring of 2020 given the number of COVID deaths and the size of the UK population.

[24][25] She was one of the three authors of the Great Barrington Declaration in 2020, which advocated lifting COVID-19 restrictions on lower-risk groups to develop herd immunity through infection, while stating that vulnerable people should be protected from the virus.

[26][24][25] The World Health Organization, as well as numerous other academic and public-health bodies, stated that the strategy proposed by the declaration is dangerous, unethical, and lacks a sound scientific basis.

[27][28] The American Public Health Association and 13 other public-health groups in the United States said in a joint open letter that the Great Barrington Declaration "is not a strategy, it is a political statement" and said it was "selling false hope that will predictably backfire".

[29] In 2021, she was an author at the Brownstone Institute, a new think tank founded by Jeffrey Tucker where senior roles were held by Martin Kulldorff and Jay Bhattacharya, her co-authors on the Great Barrington Declaration.
