Authoritative Study Shows Zero Transmission of COVID-19 by Asymptomatic Carriers

A research study conducted between May 14 and June 1, 2020, involving almost 10 million residents of Wuhan, China, found that there was zero transmission of COVID-19 from asymptomatic carriers of the disease. The report revealed that “[a]ll city residents aged six years or older were eligible and 9,899,828 (92.9%) participated.” The researchers identified 300 asymptomatic positive cases. The researchers then closely contact traced the asymptomatic persons who tested positive for COVID-19. They found that “[t]here were no positive tests amongst 1,174 close contacts of asymptomatic cases.”

Consider the significance of that study. The lockdowns, social distancing, and mask mandates are all based on the premise that those with no symptoms of COVID-19 can still spread the disease. The mainstream media will not touch the story. It is left to independent news outlets to report it. For example,  In a December 20, 2020 article by Sundance writing for THe Conservative Treehouse, the author asks: “If there is no asymptomatic spread then what is all of this mask wearing nonsense and shut-down mandates all about?” Sundance explains:

One might suppose that this would be huge news. It would allow us to open up everything immediately. With the whole basis for post-curve-flattening lockdowns crumbled, we could go back to living a normal life. The fear could evaporate. We could take comfort in our normal intuition that healthy people can get out and about with no risk to others. We could take off our masks. We could go to movies and sports events.

… We keep hearing about how we should follow the science. The claim is tired by now. We know what’s really happening. The lockdown lobby ignores whatever contradicts their narrative, preferring unverified anecdotes over an actual scientific study of 10 million residents in what was the world’s first major hotspot for the disease we are trying to manage. You would expect this study to be massive international news. So far as I can tell, it is being ignored.

The silence from the corporate media outlets about this study is deafening. Here we have a study that shows zero spread of COVID-19 from asymptomatic carriers and there is no coverage of that study. “A total of 1174 close contacts of the asymptomatic positive cases were traced, and they all tested negative for the COVID-19.”

Sundance states:

Like the common cold and flu when a person is infected with the virus they are only infecting others when they have symptoms: cold, runny nose, coughing, aching, sneezing, fever, congestion etc; hence, when a person has an illness they should isolate to not spread the virus. However, when a person has no external symptoms of the virus, just like the cold and flu, they are not a risk of transmitting the virus to others.

♦ This is a major issue with massive ramifications because all of the current COVID-19 mitigation effort is based on the principle that people can carry and spread the virus while having no idea they have it, and no symptoms.

If asymptomatic transmission is not happening, and it appears with scientific certainty it is not, then all of the current lock-down regulations, mask wearing requirements and social distancing rules/decrees are based on a complete fallacy of false assumptions.

Indeed, Dr. Maria Van Kerkhove, the Technical Lead of the World Health Organization COVID-19 Health Emergency Programme is on record as far back as June 8, 2020, stating that “from the data we have, it still seems to be rare that an asymptomatic [COVID-19] person transmits onward to a secondary case.”


The unstated reason that asymptomatic carriers do not transmit COVID-19 is that the PCR test is inaccurately testing persons positive who do not, in fact, have COVID-19. The usual testing standard for a PCR test results in a COVID-19 false-positive result 97% of the time.
