Among Asymptomatic, a very small percentage may harbor the vast majority of Community’s Viral Load according to a recent Study

Unvaccinated people still should wear masks around other unvaccinated people, which means…… if unvaccinated then you had better use caution since we don’t know who is and is not vaccinated.

This research just reminds us that asymptomatic people can spread the virus (if not vaccinated) to other unvaccinated people.

About 2% of asymptomatic college students carried 90% of COVID-19 viral load levels on a Colorado campus last year, new research reveals. Furthermore, the viral loads in these students were as elevated as those seen in hospitalized patients.

“College campuses were one of the few places where people without any symptoms or suspicions of exposure were being screened for the virus. This allowed us to make some powerful comparisons between symptomatic vs healthy carriers of the virus,” senior study author Sara Sawyer, PhD, professor of virology at the University of Colorado Boulder, told Medscape Medical News.

“It turns out, walking around a college campus can be as dangerous as walking through a COVID ward in the hospital, in that you will experience these viral ‘super carriers’ equally in both settings,” she said.

“This is an important study in advancing our understanding of how SARS-CoV-2 is distributed in the population,” Thomas Giordano, MD, MPH, professor and section chief of infectious diseases at Baylor College of Medicine in Houston, told Medscape Medical News when asked to comment on the research.

The study “adds to the evidence that viral load is not too tightly correlated with symptoms.” In fact, Giordano added, “This study suggests viral load is not at all correlated with symptoms.”

Viral load may not be correlated with transmissibility either, said Raphael Viscidi, MD, when asked to comment. “This is not a transmissibility study. They did not show that viral load is the factor related to transmission.”

“It’s true that 2% of the population they studied carried 90% of the virus, but it does not establish any biological importance to that 2%,” added Viscidi, professor of pediatrics and oncology at the Johns Hopkins University School of Medicine, Baltimore, Maryland.

The 2% could just be the upper tail end of a normal bell-shaped distribution curve, Viscidi said, or there could be something biologically unique about that group. But the study does not make that distinction, he said.
