Serious question, not trying to prove a point. Can a person catch Covid19 twice? If so how can a vaccine work? If not is there a purpose for someone who has had covid to get the vaccine?
Late to this discussion, but this caught my eye. I caught it from my boss being an shiny happy person, so did the whole shop and his wife. Some friends that already had it formed a Facebook chat for support and discussions, they invited me in. One friend mentioned the first time he had it this summer it felt like the cold/flu symptoms. Now the second time he's still dealing with after effects like getting out of bed and showering feels like he ran a marathon.
As for the topic, I won't be first in line but I'll join in fairly quick.
Has he tested positive for it twice, or is he just assuming?
This is not toward you specifically, but just in general, I see lots of people self-diagnosing themselves with all kinds of different things because they spent 90 seconds reading webMD or the Mayo Clinic site.
I can't speak for that person, but there have been thousands of cases documented by the CDC of people having multiple, tested, confirmed cases of C19.
Do you have a link for that? I can not find any hard evidence where this was proven.
I'm not arguing against that this hasnt happened, I just havent found any data on it and I would like to see it.
Thanks!
Let me look for it. A few weeks ago, the NPR show 1A interviewed a doctor from the midwest somewhere who currently had C19 and it was his fourth time. Obviously not just that he felt sick, but in his profession he was tested almost daily. He was clear that he tested negative, positive, negative, positive,.... not just "I feel sick again." He was required by law to test and document it.
NBC reported way back in the summer about how the second "wave" was showing how our own immunity doesn't last and (paraphrasing here) "thousands of of people who have already been infected are fighting the disease again." The story continued with statistics, but the basic story was "a bunch of folks got it more than once"
The CDC's official statement is (understandably) weaksauce, but has confirmed that multiple cases have occurred in Asia. They are basically saying "we don't now everything yet, so we're not saying final answer, but evidence points toward...."
From CDC:
Reinfection is known to occur with other human coronaviruses (HCoVs) 2. A study in Kenya found that 4%–21% of people infected with endemic coronaviruses (HCoV-229E, NCoV-NL63, and HCoV-OC43) had two or more episodes of infection with the same virus species during a six-month period3. Another study of HCoVs that used an antibody increase as a proxy for reinfection found that reinfections occurred at a median of 30 months but could occur as early as 6 months following the first infection4. However, immunologic data on durability of immunity for SARS-CoV-2 are limited6. Of note, South Korea has documented RT-PCR-confirmed COVID-19 cases that became undetectable by RT-PCR, then subsequently tested positive again by RT-PCR within 35 days
Buried in this story from ABC, the CDC confirms re-infection cases in Asia and Europe
This story documents a woman in the US who tested positive and had symptoms in March, tested negative later, then tested positive again in September with symptoms again. This one, the CDC hasn't accepted until they do a full genetic test on the virus from both of her infections.
USA Today, CNN, MSN, Forbes, and NPR all have links to dozens of cases of reinfection. The CDC announced in June of this year that it has received multiple cases of reinfection and is investigating. They're aware of it, and have reported it, and released this set of guidelines to states for the reporting criteria:
From CDC via MSN:
• Adults age 18 or older,
• Laboratory-confirmed positive case with clinical recovery for about 10 days after symptoms start, or after diagnosis for those that are symptom-free,
• And any one of the following:
• Two documented negative PCR (polymerase chain reaction) tests followed by a positive result;
• Recurrence of symptoms with positive PCR results;
• Positive PCR results for more than 30 days without any recurrence of symptoms.
