AI-generated doctors on YouTube are targeting elderly viewers with health misinformation, amassing at least 70 million views across 29 Portuguese-language channels. The videos use synthetic faces and voices to promote dubious remedies, often without consent from real doctors. Google says its rules ban medical misinformation that can cause real-world harm.

Key Facts

At least 29 Portuguese-language YouTube channels used AI-generated doctors and collectively gained no less than 70 million views.
BBC Brazil identified at least 50 YouTube channels with instructions on creating AI doctor videos in nine languages, including Portuguese, English, Hindi, Spanish, French, Italian, Polish, German, and Turkish.
An 82-year-old viewer, Celi Ferreira, believed an AI-generated doctor was real despite YouTube's AI label, and the video she watched had nearly 300,000 views.
A real doctor whose image was used without permission warned that fake medical advice could cause 'fatal harm' to elderly people.

Scale of the Network

The investigation uncovered 29 Portuguese-language channels using AI-generated doctors, with a combined total of at least 70 million views. BBC Brazil found at least 50 YouTube channels offering instructions on creating AI doctor videos in nine languages. The channels target elderly viewers, whom creators consider a profitable niche due to more free time and disposable income. The videos follow a formula: a trustworthy figure in a white coat warns that a common product or habit threatens health, then promotes an allegedly forgotten remedy.

Viewer Impact

Celi Ferreira, 82, watched a video where an AI-generated doctor advised eating fruit to preserve eyesight, and she believed it was a real physician. The video Ferreira saw was labeled as AI-generated but still gained nearly 300,000 views and hundreds of comments. Researchers collected about 27,000 comments under videos on these channels and used screening to identify users reporting behavioral changes. A real doctor whose image was used without consent warned that fake medical advice could have serious consequences and cause 'fatal harm' to elderly people.

Platform Response

Google, which owns YouTube, stated that platform rules apply to AI-generated content and prohibit medical misinformation that can cause serious real-world harm. In some cases, the AI doctors are entirely fictional; in others, AI copies the appearance, voice, or identity of real doctors without consent. The report was produced by the Brazilian nonprofit journalism organization CTRL+Z, and BBC Brazil examined the channels to identify patterns.
