Abstract

We used random sampling to estimate the prevalence of severe acute respiratory syndrome coronavirus 2 infection in Verona, Italy. Of 1,515 participants, 2.6% tested positive by serologic assay and 0.7% by reverse transcription PCR. We used latent class analysis to estimate a 3.0% probability of infection and 2.0% death rate.

Keywords: 2019 novel coronavirus disease; COVID-19; IgG; Italy; RT-PCR; SARS-CoV-2; coronavirus; coronavirus disease; latent class analysis; random sample survey; respiratory infections; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
