A new University of California San Diego study published in Cell challenges a long-standing assumption about how animal viruses become capable of sparking human epidemics and pandemics. Using a ...

Study shows zoonotic viruses like SARS-CoV-2 can transmit between humans without prior adaptation, unlike lab-passaged viruses.

Contrary to prevailing belief, an evolutionary analysis finds no evidence that most viruses with epidemic or pandemic ...

There is no evolutionary signal suggesting that these viruses were being “pre-adapted” for humans prior to their outbreaks. Instead, measurable changes in selection typically appeared only after ...
