USA: At least 125,000 vaccine breakthrough infections, 1,400 dead

At least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died, according to data collected by NBC News.  The total number of breakthrough cases is likely higher than 125,683, since nine states, including Pennsylvania and Missouri, did not provide any information, while 11, like Florida, did not provide death and hospitalization totals. Four states gave death and hospitalization numbers, but not the full tally of cases.

WAPO: 35,000 symptomatic Covid-19 infections per week among 162 million vaccinated Americans

Just 2% of #coronavirus−positive individuals carry 90% of the virus circulating in communities

We analyzed data from saliva-based COVID-19 screening deployed on the University of Colorado Boulder campus. Our dataset is unique in that all SARS-CoV-2−positive individuals reported no symptoms at the time of saliva collection, and therefore were infected but asymptomatic or presymptomatic. We found that 1) the distribution of viral loads observed in our asymptomatic college population was indistinguishable from what has been reported in hospitalized populations; 2) regardless of symptomatic status, approximately 50% of individuals who test positive for SARS-CoV-2 seem to be in noninfectious phases of the infection; and 3) just 2% of infected individuals carry 90% of the virions circulating within communities, serving as viral “supercarriers” and likely also superspreaders
