Abstract

Positive-strand RNA viruses have been the cause of several recent outbreaks and epidemics, including the Zika virus epidemic in 2015, the SARS outbreak in 2003, and the ongoing SARS-CoV-2 pandemic. On June 18-22, 2022, researchers focusing on positive-strand RNA viruses met for the Keystone Symposium "Positive-Strand RNA Viruses" to share the latest research in molecular and cell biology, virology, immunology, vaccinology, and antiviral drug development. This report presents concise summaries of the scientific discussions at the symposium.

Keywords: RNA virus; SARS-CoV-2; alphavirus; coronavirus; enterovirus; flavivirus.

Colored filled rectangles represent parts of the genome in C2R1, C2R5, and C2R10 viruses that are present in the respective passage. Virus isolates names are in bold. Horizontal black lines indicate deleted parts of the genome with the respective size denoted by Δ, starts and ends of the deletions are indicated by the respective nucleotide position.
