Can you get COVID from an asymptotic person?

(Ron) #21

So my local college football team has been allowed to get back to practices but one of the requirements was they had to be tested and pass that test. What was eye opening to me is that there were a number of players that actually tested positive and have to do the 2 week quarantine thing. These players showed no signs of Covid 19 and were unaware they were infected. That is a little perplexing to me??? So many questions are raised from this. What is the difference in there bodies to do that? Is the test really accurate? etc etc.

It’s puzzling to me also.

I posted this earlier on this thread but the same thing happened at Arkansas State where 7 athletes who were using the facility to work out tested positive with no symptoms. They will be quarantined for 14 days and contact tracing started. It would be interesting to know if they infected anyone. Of course no way to know if the infected person got it from the asymptomatic athlete or not, but if nobody got sick it is more evidence you normally don’t infect someone else when not sick.

This is from spell-checker, no? :slightly_smiling_face::wink:

No spell checker on my work laptop. Aggravating!!! IT Nazis win again.

THis has been walked back significantly.

A top World Health Organization official clarified on Tuesday that scientists have not determined yet how frequently people with asymptomatic cases of Covid-19 pass the disease on to others, a day after suggesting that such spread is “very rare.”

The clarification comes after the WHO’s original comments incited strong pushback from outside public health experts, who suggested the agency had erred, or at least miscommunicated, when it said people who didn’t show symptoms were unlikely to spread the virus.

I was watching this news report about this Virus Surveillance Specialist at Harvard University Dr. John Brownstein showing time enhanced satellite images of different hospital parking lots in Wuhan China around October 2019 long before the news reports about the first death or deaths from Covid-19.

That then makes me wonder, what about three months before that (October 2019)? I got really sick from somebody that had been exposed to Airline passengers from China and it was not the Flu, around March of last year. I never have been that sick in my life and the person who I got it from ended up on ventilator in my living room? I now wonder if I have any evidence of anti-bodies from COVID-19 and I did wear a mask at that time too keep from infecting other people because I was really sick and felt like I was knocking deaths door. If that’s what it was, am I now immune? Could I infect other people? The virus itself has two known pathways to infect the host and maybe it can go dormant then reappear later.

Then I think to myself maybe your just over-thinking this and just being hysterical!


In South Korea there was one asymptomatic woman who attended church and set off a cluster of more than 100 people. They did a lot of testing and tracing fast when the cluster appeared. That asymptomatic spread is what is so problematic about this virus.

Of course they walked it back - doesn’t fit the narrative.

(Peter) #29

Let me get this right - you believed the WHO when you agreed with what they said, but that very same WHO is now lying because you, with all your evidence and experience (i.e. getting things completely wrong on here on a daily basis) disagree? And that change of mind is inside 24 hours?


(Jane) #30

I believed the individual, not WHO and she was quickly marginalized. And yes, I believed her because I agree with her. Doesn’t mean either of us is right.

(SammyOlsen) #31

I totally agree. This is not true

Our local massage clinic had to close for 2 weeks when one of their clients tested positive for COVID after she had been there. Test was done before her appointment and results came after. She was asymptomatic.

None of the therapists tested positive for the virus when they were tested 2 weeks later and she came in with her daughter and did a massage together in the same room, so 2 therapists had close contact with the lady. Her daughter never got sick either.

I got to thinking about having the virus and being asymptomatic… wouldn’t that mean you would have no immune response such as fever? If that is the case, how long does the virus stay in your system with nothing fighting it? If the lady has to have a negative test in order to return to work I wonder how long that might be? Her employer ordered the test.

Five weeks my brothers fiancé was testing positive for and never had any symptoms at all

(Jane) #34

Did she finally test negative after the 5 weeks? What an ordeal.

(Allie) #35

Yes eventually. She was held in hospital isolation the whole time, tested twice weekly and had to test negative twice before she could go home. Then a weekend of rest, and back to work at the hospital where she’s a nurse and picked up the virus in the first place.

(Jane) #36

Well that’s an n=1 then - 5 weeks to shed the virus with no symptoms. Poor dear - 5 weeks of isolation must have been difficult - especially if she felt fine.

With the virus circulating since early March there can be a lot of people who had it with no symptoms and now just maybe show antibodies.

Did anyone close to her get sick? I still wonder how contagious a person is if they have no symptoms.


SARS-CoV-2 has all the same genetic equipment as the original SARS-CoV, which caused a global outbreak in 2003, but with around 6,000 mutations sprinkled around in the usual places where coronaviruses change. Think whole milk versus skim milk.

Compared to other human coronaviruses like MERS-CoV, which emerged in the Middle East in 2012, the new virus has customized versions of the same general equipment for invading cells and copying itself.

However, SARS-CoV-2 has a totally different set of genes called accessories, which give this new virus a little advantage in specific situations. For example, MERS has a particular protein that shuts down a cell’s ability to sound the alarm about a viral intruder.

Asymptomatic people still fight the virus but they won’t have the more serious symptoms of fever. Just the lesser symptoms associated with reduced blood pressure… tiredness or reduced energy levels and/or mild dry cough or sneezing and/or diarrhea.

(Jane) #38

So is 5 weeks after the initial infection.symptoms a good ballpark estimate to get a negative test? Symptomatic or not?


I doubt it for A+ and maybe AB+ blood types or unhealthy O+'s.

It’s also important to distinguish between a true asymptomatic and someone who can’t get infected at all. I don’t believe negative blood types can be infected because my 86 year old O- grandma had zero symptoms while being around many infected people but I’d like to be proven wrong.

What I’ve noticed is that healthy O+ had symptoms of viral clearance and not symptoms of viral infection. Sneezing, mild cough and diarrhea are symptoms of viral clearance. I experienced the sneezing only when I was clearing the virus.

The situation is a lot more complex than it looks because an A+ taking medication that is also antiviral will clear the virus faster than an unhealthy O+.

She wasn’t totally isolated, but kept in an area of the hospital with everyone else who had tested positive (in The Philippines) where they basically waited to see who got symptoms and needed more care, and who didn’t.

The weekend before her first positive test she’d been at home with my brother and his daughter, neither of them got sick.
