Biswaroop Roy Chowdhury

Biswaroop Roy Chowdhury is a self-proclaimed doctor known for peddling medical conspiracy theories, including denialist conspiracies about COVID-19, HIV/AIDS, and diabetes, for which he has been heavily criticized. His multiple YouTube and social media accounts have been terminated for spreading misleading health advice. 
He is the author of several self-published books and creator of two films. In 2005 he worked in Hindi movie "Yaad Rakhenge Aap", which claimed could somehow enhance the viewer's memory, and in 2006 announced "Kabhi Alvida Naa Kehna", which triggered a dispute with director Karan Johar, who was making his own film under the same name; both claimed that the title was registered with them.
In August 2020, during the first peak of the COVID-19 pandemic in India, Chowdhury uploaded a video on YouTube calling for dropping the use of face masks, making the false claim that it is an ineffective way to control the virus. He cautioned against COVID-19 vaccines and said: "If anyone influences you to take the vaccine, he is part of a group that wants to end your life and property." Several of his conspiracy theories have been debunked by multiple media outlets such as Firstpost, including his claims that masks are a method of slavery and that they are ineffective at containing virus droplets. His YouTube video promoting anti-mask conspiracy theories was taken down by Twitter for violating their terms of use.
Indian health officials have referred to his "miracle diabetes cure" as fraud. A criminal complaint was filed against Chowdhury for falsely claiming to be a medical practitioner, offering fraudulent treatments, and failing to provide emergency care at courses he has run.
The Consumer Complaints Council (CCC) of the Advertising Standards Council of India (ASCI) in 2016 and 2017 found Chowdhury's advertisement claiming 'Diabetes Type 1 & Type 2 Cure in 72 Hrs' was false and grossly misleading. ASCI further stated that in making claims of curing diabetes, the advertisement was in breach of the law as it violated the Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954.
Despite Chowdhury's claims he is a doctor, he has no formal qualifications or medical training. He reportedly received a bogus honorary PhD in "diabetes science" from Alliance International University in Zambia, which is not accredited.
Chowdhury reportedly runs a fake online University named World Records University that sells fraudulent PhD.
