Estimate of COVID-19 seroprevalence in the US suggests few in the population developed antibodies in the first wave

Researchers from Stanford University explain that patients on dialysis represent an important population to study general COVID-19 seroprevalence. These patients already undergo routine, monthly laboratory studies and represent similar risk factors to contracting COVID-19 as the general population, including age, non-white race, and poverty. Unlike community-based surveys, where a select group may show up for or agree to be tested and require a significant on-the-ground effort to launch, patients on dialysis are amenable to random sampling as part of their routine care. The study follows previous findings from recent seroprevalence studies of highly affected countries and regions (e.g. Wuhan, China, and Spain), which have shown that despite the intense strain on resources and unprecedented excess mortality, rates of seroprevalence at the population level remain low. Other seroprevalence studies of the U.S. population have been restricted to regional hotspots, such as New York City….
