Study: Asymptomatic Spread Of COVID May Be Rare

According to a new study asymptomatic spread of The Chinese Coronavirus might actually be extremely rare.

Just The News:

A study published this month in the American Medical Association’s JAMA Network Open journal has offered further evidence that asymptomatic spread of COVID-19 may be significantly lower than previously thought.

Fears of COVID-19 spreading asymptomatically have persisted since shortly after the beginning of the pandemic. Many public health authorities in the United States and elsewhere initially argued that only those individuals with symptoms of COVID-19 should take precautions such as wearing masks and staying at home.

But fears that the virus may be spread to a significant degree by asymptomatic carriers soon led government leaders to issue broad and lengthy stay-at-home orders and mask mandates out of concerns that anyone could be a silent spreader.


In the new study published in the JAMA Network Open journal, a team of researchers from the University of Florida and the University of Washington conducted a “meta-analysis of 54 studies with 77,758 participants” to determine “the estimated overall household secondary attack rate” of COVID-19. (The “secondary attack rate” of a virus, according to the Centers for Disease Control and Prevention, quantifies “transmission of illness in a household, barracks, or other closed population” compared to transmission in the wider community.)

The authors determined that symptomatic cases were far more likely to transmit the virus than asymptomatic ones. The “secondary attack rate” of symptomatic cases was 18%, they found, compared to 0.7% for asymptomatic ones, a 25-fold difference. 

“The lack of substantial transmission from observed asymptomatic index cases is notable,” the authors argue. “These findings are consistent with other household studies reporting asymptomatic index cases as having limited role in household transmission.”

Two British Experts questioned why we are doing mass testing of asymptotic people: 

Searching for people who are asymptomatic yet infectious is like searching for needles that appear and reappear transiently in haystacks, particularly when rates are falling.19 Mass testing risks the harmful diversion of scarce resources. A further concern is the use of inadequately evaluated tests as screening tools in healthy populations

The UK’s testing strategy needs to be reset in line with the Scientific Advisory Group for Emergencies’ recommendation that “Prioritising rapid testing of symptomatic people is likely to have a greater impact on identifying positive cases and reducing transmission than frequent testing of asymptomatic people in an outbreak area.”21

Testing should be reintegrated into clinical care with clinical and public health oversight and case definitions based on clinical diagnosis. Carefully designed prospective studies of cases and contacts are needed to estimate transmission rates by people with and without symptoms. These should include careful investigations of outbreaks—for example, testing all contacts of people with a clear history of exposure, especially in high risk environments such as nursing homes, prisons, and other institutional settings.

Bottom line is that the experts have no clue what they are talking about.

One moment they claim one thing until they claim something else.

They yell at you to follow the science. Turns out they are the ones that don’t.
