As Many as 50 Percent of People with COVID-19 Aren’t Aware They Have the Virus

When police, law makers, judges, government departments break and ignore the law they have sworn to uphold, then there isn't any law - just a fight for survival.

These days so many governments around the planet seem to be having a lot of trouble following their own rules, and seem to believe in selective enforcement, this section is here to try to help people find ways (preferably non-violent ways) to survive the tyranny.

As Many as 50 Percent of People with COVID-19 Aren’t Aware They Have the Virus

If we have the virus and it does not make us sick, why are we to be shot, fined, arrested, etc. if we dare go outside?

As Many as 50 Percent of People with COVID-19 Aren’t Aware They Have the Virus



All data and statistics are based on publicly available data at the time of publication. Some information may be out of date. Visit our coronavirus hub and follow our live updates page for the most recent information on the COVID-19 outbreak.

There may be a lot of people walking around who have COVID-19 but have no idea they are spreading the virus.

The first word of this possibility came in early April from the Centers for Disease Control and Prevention (CDC) director, Dr. Robert Redfield, in an interview with National Public Radio affiliate WABE.

“One of the [pieces of] information that we have confirmed now is that a significant number of individuals that are infected actually remain asymptomatic. That may be as many as 25 percent,” Redfield said.

Then a few days later, researchers in Iceland reported that 50 percent of their novel coronavirus cases who tested positive had no symptoms. The testing had been conducted by deCODE, a subsidiary of the U.S. Biotech company Amgen.

In another new reportTrusted Source, the CDC stated that researchers in Singapore identified seven clusters of cases in which presymptomatic transmission is the most likely explanation for the occurrence of secondary cases.

That report was backed up by a studyTrusted Source published in mid-April that concluded that people with no symptoms are the source of 44 percent of diagnosed COVID-19 cases.

In addition, a studyTrusted Source published about the same time reported that people might be most contagious during the period before they have symptoms.

Then, in late April, it was reported that the first known person to die from COVID-19 in the United States before she died of a heart attack on February 6 at her home in Northern California


“Of those of us that get symptomatic, it appears that we’re shedding significant virus in our oropharyngeal compartment, probably up to 48 hours before we show symptoms,” Redfield said. “This helps explain how rapidly this virus continues to spread across the country because we have asymptomatic transmitters.”


How transmission works

“It isn’t a strange idea with respiratory viruses that such an inadvertent transmission could take place,” said Dr. William Schaffner, an infectious disease expert from Vanderbilt University Medical Center in Tennessee.

“It’s to the virus’ benefit because if you have seemingly healthy people moving around spreading the virus, that maximizes the transmission,” he told Healthline. “Once you get sick, you tend to restrict your encounters with others.”

To demonstrate how fast the virus transmission works among people who may be unwittingly infecting others, Dr. James Hildreth, president and chief executive officer of Meharry Medical College and an infectious disease expert, illustrated the spread in a public service announcement.

He said people who study virus spread assign viruses basic reproductive spread numbers.

“One that comes to mind is measles. Measles is one of the most contagious viruses we’ve ever known and its number is somewhere between 12 and 18,” Hildreth told Healthline.

“By comparison, the COVID-19 virus, it’s basic reproductive number appears to be about 4. What that means is that each person who is infected by the virus has the potential to spread it to four other persons in a susceptible population,” he explained.

“If you do the math, the number of people infected would double every 6 days or so. But the actual data in some parts of the country is the virus is doubling every 3 days,” Hildreth added.

He noted that this novel coronavirus that began in December in a market in Wuhan, China, has infected 1.4 million people in 4 months.

“When you’re dealing with a virus like that, everything we can do to break the chain of transmission is exceedingly important because there are people who are spreading the virus and are not aware of it,” he said.


This makes masks more important

After first telling the public there was no need for anyone to wear a mask unless you were sick or coughing, the CDC did an about-face in early April.

Now, the agency is recommending people wear a face covering if they go to a public place.

They’ve posted instructions Trusted Source on how to properly wear a cloth mask.

But does a cloth mask work?

“It actually works in both directions,” said Schaffner. “But we’re more sure that masks inhibit the spread out rather than the acquisition in.”

Why the CDC reversal?

“Two reasons. One is very practical. Early on, they didn’t want there to be a run on masks and respirators by the general public, siphoning them off from the healthcare environment. That was a very real concern,” Schaffner said.



“The second thing is the appreciation of presymptomatic transmission has become more evident over time,” he added. “It takes a little bit of time for those discussions to go on and for everyone to agree to ask the American public to do something that is culturally alien.”

And Schaffner believes the masks have a psychological benefit at a time when very little seems in our control.

“Putting on a mask is something I can do to help protect me and it will help protect my family. It makes people feel good to do something,” he said. “And when you see others wearing a mask, it builds a sense of community.”
