As a science journalist, I’ve learn dozens of investigative papers on COVID-19, and I’ve interviewed so many virologists, infectious illness medical doctors, and immunologists within the final two years that I’ve misplaced rely. However nothing ready me for what occurred after my 7-year-old daughter examined constructive for COVID-19 nearly two weeks in the past.
It began out the way in which you’d count on: One Sunday evening, my daughter got here down with a fever. The following morning, we acquired an electronic mail informing us that she had been uncovered to coronavirus Friday at college. I did a speedy antigen check, which rapidly got here again constructive. I resigned myself to the chance that the entire household would ultimately catch COVID-19.

However we did not, not precisely. I, in my opinion, by no means developed signs or examined constructive. The day my daughter first examined constructive, my 11-year-old son introduced that he was not feeling properly and commenced creating the traditional signs of coronavirus: headache, fatigue, sore throat, runny nostril. My husband adopted up two days later with a sore throat and nasal congestion. Nevertheless, regardless of every day testing for seven days in a row, my husband and son by no means examined constructive for COVID-19, even in PCR checks administered on my son’s fifth symptom day and my husband’s third. (And sure, we additionally did some throat swabs.)
We rack our brains over what might have occurred: Did my husband and son get COVID, although they by no means examined constructive? Or did they’ve one other virus that induced similar signs and contaminated them proper after they had been uncovered to COVID-19? (Our pediatrician stated that was unlikely.) Why hadn’t I gotten sick? I referred to as in immunology consultants, microbiology and virology to get their opinion.
Vaccination modifications the way in which your physique reacts to the virus.
One of many first questions the consultants requested me was whether or not my household was vaccinated. Sure, I stated: my husband and I are vaccinated and boosted, and our youngsters are vaccinated however not but boosted. This can be a related query as a result of for those who’re uncovered to the virus that causes COVID-19, “your immune system kicks into motion a lot sooner for those who’re vaccinated than for those who’re not vaccinated,” stated Gigi Gronvall, an immunologist on the Johns Hopkins Heart for Well being Safety in Baltimore. And this fast response modifications the whole lot about what occurs subsequent.
First, the speedy immune response slows the speed of viral copy and unfold “That is what vaccines are for: to coach your immune system so it may well pounce on invaders earlier than they’ll replicate uncontrolled,” Gronvall stated. As a result of the virus doesn’t replicate as rapidly in vaccinated individuals, they’re much less prone to check constructive for COVID-19 after publicity to the coronavirus, as a result of their immune system “maintains the viral load under the detection stage.” stated Juliet Morrison, a microbiologist on the College of California, Riverside.

So my husband and son could have contracted COVID-19, however their vaccinations immune system they defended the an infection so properly that they by no means had sufficient viral protein of their nostril or throat to check constructive. And their unfavourable checks probably meant they had been by no means that contagious, Morrison stated.
Nonetheless, my husband and son adopted the Facilities for Illness Management and Prevention tips, which say that for those who’re vaccinated, have been uncovered to COVID-19, and develop signs, however check unfavourable, it is best to proceed to make use of a masks when round different individuals. for 10 days. In truth, everybody with signs in the home was stored out of the general public for seven days. I ran just a few errands however wore an N95 or KF94 masks once I did, in case I used to be hatching a an infection.
To cut back the unfold between members of the family, we opened home windows, ate exterior, and wore masks after we remembered, however I will be trustworthy and admit that our precautions relaxed after a number of days, particularly as soon as my husband and son additionally developed signs. .
You might really feel sick even when the virus is underneath management.
If my husband and son by no means examined constructive, why did they really feel sick? Even when a vaccinated particular person does not have a lot virus of their physique, they’ll nonetheless have highly effective COVID signs, consultants informed me. That’s as a result of many signs of sickness — fever, malaise, runny nostril, fatigue — are literally attributable to the immune system’s response to the virus, relatively than the virus itself, Gronvall stated.
And as for why I felt high-quality, Morrison stated that perhaps my immune system fought off the incoming virus so rapidly that I did not actually have a probability to really feel sick.
“It appears to me that you just had been positively uncovered,” Morrison informed me. However, he defined, he could have had excessive ranges of the vaccine. antibodies or immune cells referred to as T cells that had been capable of kill the invading virus earlier than it had an opportunity to alert the elements of my immune system that will immediate signs.
All that stated, nobody actually is aware of what occurred to me, my son, or my husband.
On the subject of understanding how COVID-19 impacts the physique, “there are such a lot of open questions,” stated Raúl Andino, a virologist on the College of California, San Francisco, and folks can have totally different experiences for a lot of totally different causes. For instance, Andino stated, it’s attainable that the virus is replicating in elements of my husband’s or my son’s physique that the checks didn’t attain. Analysis means that the coronavirus can replicate within the pancreas, coronary heart, mind, kidneys and different organs, though vaccination could scale back the prospect of the virus spreading exterior the physique. respiratory system.
My household isn’t the one one who has had the unusual expertise of creating coronavirus signs however repeatedly testing unfavourable. Andino stated he and his colleagues have been conducting research wherein they repeatedly observe and check total households after one particular person within the family checks constructive for COVID-19.
“What we see is precisely what you described: that some individuals within the family aren’t testing constructive,” although they’ve signs, he stated. Once I requested my Instagram followers if that they had an expertise like my household’s, I bought dozens of sure solutions and tales that sounded lots like ours.
Most individuals with publicity to and signs of COVID-19 will ultimately check constructive.
The consultants I spoke with additionally made a vital level: There’s a distinction between by no means testing constructive and never testing constructive but. My husband and son continued to get examined for every week after creating signs, so my sources stated it was unlikely they’d ever check constructive. However many individuals solely strive for a few days and, frustratinglyyou possibly can’t draw clear conclusions from simply a few unfavourable checks.
As I stated earlier, when individuals get vaccinated in opposition to COVID-19, their immune methods rapidly put together to struggle it off, typically creating signs prior to anticipated. not vaccinated individuals do, just a few days earlier than they’ll check constructive. So when individuals solely get examined just a few days after creating signs, their unfavourable outcomes do not essentially imply they do not have COVID-19. Nevertheless, some individuals assume at that time that they don’t have the coronavirus and cease taking precautions.
“They’ll calm down mitigation measures when they’re nonetheless shedding fairly a little bit of virus,” Gronvall stated.
Given these findings, Gronvall stated that ideally, individuals who have acquired two or three doses of the vaccine ought to get examined as soon as they begin to develop signs, however proceed to get examined on day 4 or 5 of signs, as checks that come again unfavourable earlier than that date could be falsely reassuring. . Nevertheless, to do that, you will need to have entry to many checks. Happily, now you can get a 3rd spherical of free COVID-19 checks by the US authorities, and there may additionally be free testing websites close to you.
As for our household, now everybody has absolutely recovered. the thriller that perspiring in our home it continues to eat away at me, however it’s far outweighed by my aid at having had such a gentle expertise, and for this, we’ve our COVID-19 vaccinations to thank.
