Targeting Polyamines Inhibits Coronavirus Infection by Reducing Cellular Attachment and Entry.

Coronaviruses first garnered widespread attention in 2002 when the severe acute respiratory syndrome coronavirus (SARS-CoV) emerged from bats in China and rapidly spread in human populations. Since then, Middle East respiratory syndrome coronavirus (MERS-CoV) emerged and still actively infects humans. The recent SARS-CoV-2 outbreak and the resulting disease (coronavirus disease 2019, COVID19) have rapidly and catastrophically spread and highlighted significant limitations to our ability to control and treat infection.
