High individual-level variability in SARS-CoV-2 shedding may explain superspreading


High individual-level variability in SARS-CoV-2 shedding may explain superspreading
Researchers in the United States have provided a high-resolution description of the viral dynamics involved in acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).
The team’s daily longitudinal sampling of 60 newly infected individuals revealed that significant person-to-person variation in the shedding of infectious virus contributes to superspreading.
Superspreading is the term used to describe a small fraction of infected individuals accounting for a disproportionate level of community transmission.
“These results provide the first high-resolution, multi-parameter empirical profile of acute SARS-CoV-2 infection in humans and implicate person-to-person variation in infectious virus shedding in driving patterns of epidemiological spread of the pandemic,” writes Christopher Brooke from ....

Frequent testing increases chance of detecting COVID-19 infections


Frequent testing increases chance of detecting COVID-19 infections
The chance of detecting the virus that causes COVID-19 increases with more frequent testing, no matter the type of test, a new study found. Both polymerase chain reaction and antigen tests, paired with rapid results reporting, can achieve 98% sensitivity if deployed at least every three days.
This study shows that frequent testing can be really effective at catching COVID-19 infections and potentially blocking transmission. There are many places where vaccination is not yet widespread. With the rise of variants, testing remains an important tool for blocking the spread of the virus.
