Dubious Covid treatments explode on social media as China cases rise

Chinese are turning to social media influencers and celebrities for tips about treating Covid, after the country’s whipsaw reversal in virus strategy undermined trust in government advice and health officials.

China’s rapid dismantling of pandemic restrictions over a matter of weeks at the end of last year led to a quick surge in infections, with Covid spreading through cities and towns that have had little experience with the virus until now. With the government hastily retreating, people are increasingly looking to social media for answers, resulting in a corresponding increase in misinformation and even dangerous advice.

Search queries about treating common Covid maladies, from whether the XBB sub-variant causes diarrhea to how best to treat pneumonia, throw up a raft of responses on the Chinese Internet: adopt a vegan diet, take multiple antibodies, or even ways to buy illegal enzymes from online celebrities.  

Throughout the pandemic, people in many countries—particularly those where the government’s approach to the virus was questioned or was ineffective—also turned to untested remedies and online advice. The US craze for Ivermectin, which is primarily approved to treat diseases caused by parasites in livestock and humans, is a prime example. 

What makes China’s rush different is that it’s being accompanied by corresponding backlash against the government. 

News stories and social media posts on Covid advice from Chinese health officials are being regularly lambasted with comments questioning their credibility, after many went from warning about the dangers of Covid to downplaying its seriousness within mere weeks, as policy completely shifted away from the stringent Covid Zero approach. 

Backlash against officials

The pushback has become so strong that the slogan “we advise experts to stop giving advice” was one of the top trending topics on Chinese social media platform Weibo earlier this month.

The result is that some Chinese are increasingly relying on influencers and others online who lack medical expertise for advice on how to treat or not contract the virus. A Weibo search for “preventing Covid” points people to nasal irrigation and “angong niuhuang” pills—traditional Chinese medicine typically used for stroke that’s made of cattle gallstones and buffalo horns, and contains arsenic and mercury. 

The lack of accurate, accessible health information has already led to at least one tragedy. China has seen widespread shortages of fever medications like ibuprofen since its reopening wave took hold. Unable to find such drugs, one family of four in Inner Mongolia, a region in China’s north, ingested veterinary medicine to treat Covid in mid-December. Their two children ended up with major liver damage.

Control of the narrative

Alton Chua, an associate professor of communications and online information at Nanyang Technological University, said the backlash against government advice set a dangerous precedent. 

“If the credibility of public experts were to be repeatedly undermined in future high-profile incidents, then I think it’d be difficult to regain confidence,” he said. 

China has used its almost total control of domestic media and the Internet within its “Great Firewall” to validate the nation’s abrupt shift from quashing all Covid cases to letting the virus loose. 

Officials have refuted claims the about-turn was triggered by damage to the economy and protests against Covid Zero, saying it was all part of the wider plan. Censors have vowed to curb online speculation about Covid over the Lunar New Year holiday, an apparent effort to prevent further anger and confusion over Beijing’s reversal on its virus policy. 

Yet the shift in rhetoric was so pronounced in some cases, it couldn’t go unnoticed. One top medical official, Zhong Nanshan, went from claiming the more contagious Omicron variant validated China’s zero-tolerance approach to Covid, to saying the strain caused little more than a “cold.”

Yoga guru peddling cures

The rise of misinformation comes as China’s reopening outbreak continues to swell, with the country saying it recorded more than 12,600 virus-related deaths the week before the Lunar New Year holiday, which is seeing many travel home to their home villages and towns. The unleashing of Covid has seen millions infected in China for the first time. 

One of those people was Lisa, a resident of Shanghai in her sixties. Anxious about catching Covid as the outbreak spiraled, to try and ward it off she spent the equivalent of thousands of dollars on enzyme drinks and eye drops touted by Yi Heng, a celebrity yoga guru who has more than a million followers on Douyin, China’s version of ByteDance Ltd.’s TikTok video-sharing app. 

The fact that the enzymes had no visible manufacturing date, certification or label of production origin didn’t faze Lisa, who declined to give her last name. Though she eventually became infected with Covid, Lisa believes the enzymes—coupled with Yi’s advanced breathing exercises—boosted her recovery.  

“I’ve never felt better,” she said. “I’m strong as a bull.”  

Yi didn’t respond to a request for comment from Bloomberg News. 

Chinese social media companies have taken some steps to curb the spread of Covid misinformation, though their efforts remain limited compared to platforms popular abroad. 

Last year, Weibo removed more than 82,274 pieces of content that it labeled as misinformation, though it didn’t specify how many were Covid-related. 

That’s lower than other international social media networks: TikTok removed more than 250,000 items for Covid misinformation, while Twitter culled 97,674 such posts in the first nine months of 2022.

Some Chinese are also trying to combat rumors proliferating online. Hetty Liu, a 33-year-old public relations manager in Shanghai, created several groups on the WeChat messenger app alongside friends with medical backgrounds to fact-check and dispense accurate health advice.

Common myths Liu’s tackled in chat rooms with some 4,000 members include that plant-based diets lower the risk of getting Covid, and the effectiveness of so-called “virus shut out” lanyards, which can contain pesticides that cause breathing issues. The lanyards have notched tens of thousands of sales on Chinese e-commerce platform Pinduoduo. 

For Liu, the mission has become personal: Some of her family members have put their trust in fake Covid cures.

“I can’t stop them from believing what they want,” she said. “People are more susceptible now because everyone’s really anxious about Covid. Everything is scary, everything is unknown.”
