An anti-vaxxer made her family drink their own urine after seeing on WhatsApp doing so would help prevent Covid-19 infection.
The bizarre account was revealed in a report by London's City of Westminster council on people's experiences during the coronavirus pandemic.
According to the report, the woman and her children drank their own urine for four days.
"She said she believed that Bill and Melinda Gates will introduce vaccinations and that they would be dangerous for her family," the report explained.
The woman had been sent the fake information by a friend who she said she relied on for her Covid information.
The British government has come under intense scrutiny for their handling of the pandemic, with key Conservative ministers accused of giving conflicting information and advice to the public.
The report stated a "lack of trust in official channels of information" had prompted a rise in fake remedies and conspiracies through apps such as WhatsApp.
The woman is believed to be French African, while her English proficiency is unknown.
Relaying key coronavirus material to those who do not speak a nation's primary language has been a major issue during the pandemic and was believed to have played a part in Melbourne's surge in cases during its second wave.
There are fears in Australia conspiracy theories about coronavirus and the vaccine could surge with Facebook banning credible news sources in a row with the federal government over paying for news.
From Thursday, Australians were unable to post links to news articles or view the Facebook pages of local and international news outlets, while Aussie news sources disappeared from the site worldwide.
"This irresponsible move by Facebook will encourage the dissemination of fake news, which is particularly dangerous during the COVID pandemic and is a betrayal of its Australian audiences," The Media, Entertainment and Arts Alliance spokesperson Marcus Strom said.
