Convalescent plasma (CP) is a potentially important therapy for coronavirus disease 2019 (COVID-19). However, knowledge regarding neutralizing antibody (NAb) titers in donor plasma and their impact in patients with acute COVID-19 remains largely undetermined. We measured NAb titers in CP and in patients with acute COVID-19 before and after transfusion through the traditional Food and Drug Administration investigational new drug pathway. ⋯ NCT04434131.

In December 2019, a novel coronavirus known as SARS-CoV-2, emerged in Wuhan, China, causing the coronavirus disease 2019 we now refer to as COVID-19. The World Health Organization declared COVID-19 a pandemic on 12 March 2020. In the United States, the COVID-19 pandemic has exposed preexisting social and health disparities among several historically vulnerable populations, with stark differences in the proportion of minority individuals diagnosed with and dying from COVID-19. In this article we will describe the emerging disproportionate impact of COVID-19 on the Hispanic/Latinx (henceforth: Hispanic or Latinx) community in the United States, discuss potential antecedents, and consider strategies to address the disparate impact of COVID-19 on this population.

To illustrate how patient risk and clinical costs are driven by false-positive and false-negative results. ⋯ We demonstrate the value of reporting probability of false-positive results, probability of false-negative results, and costs to patients and health care. These risk metrics can be calculated from the risk drivers of PPA and PNA combined with estimates of prevalence, cost, and Reff number (people infected by 1 positive SARS-CoV-2 carrier).

Coronavirus disease 2019 (COVID-19) has spread rapidly in the United States since January 2020. ⋯ Statewide mitigation strategies were strongly associated with increased epidemic doubling time.
