COVID Without Symptoms May Be Very Rare: Study

COVID Without Symptoms: A new study has surfaced today saying unvaccinated and healthy adults who contracted COVID are most unlikely to be symptom free in lieu of some other reports that say asymptomatic infection is common among infected individuals.

As per Dr. Edward Mitre who’s the professor of microbiology and immunology at Uniformed Services University of the Health Sciences (USUHS) in Bethesda, Md. states, “Some studies suggest that asymptomatic infection may occur as often as 50% of the time,” but the new research in this regard doubts on the above.

The new study was conducted by a team of researchers that included a sample size of 263 uninfected and unvaccinated individuals aged 41. All of them were healthy and had normal immune systems.

It was between August 2020 and February 2021 when all the participants were asked to undergo PCR tests right at the time of having symptoms.

In addition to the above, they were also made to undergo their monthly antibody testing so as to detect a single case of COVID that were symptom free or if it actually missed the PCR-testing.

Even before conducting the above tests, participants were also asked to report for any symptoms they incur at ant point of time.

Out of the above, 12 of them were tested positive for SARS-CoV-2 infection. The reports suggested all of them had symptoms. The above finding was published on February 14 in a report Open Forum Infectious Diseases.

The new report further suggested that even if asymptomatic infection would have occurred in participants, they would have been very unlikely.

“If we compare this to flipping a coin, the likelihood that one flips tails 12 times in a row is only 0.024%,” he said in a university news release. “Even if the true rate of asymptomatic infection is 30%, then the likelihood that 12 of 12 individuals would all be symptomatic is still only 1.4%.”

The researchers noted that since the entire study was conducted on unvaccinated participants, it might not have reflected the actual rates of asymptomatic infection in vaccinated participants.

Emilie Goguet, who was the lead author of the above research stated that they observed a higher rate of symptomatic infection as all the participants payed close attention to their individual signs of infection.

The study also compared the symptoms of 12 participants who were diagnosed with COVID-19 as compared to other 38 participants who tend to develop non-COVID-19 respiratory diseases.

Almost 70% participants (both groups) complains symptoms like sore throat, sinus pressure and Runny nose. They also had loss of taste and smell.

Now, the findings clearly show that it is quite unlikely to detect COVID-19 symptoms from other respiratory tract infections based on symptoms alone.
