>>11596241Viral load is related to risk of infection. Your odds of contracting COVID-19 from a very small number of virions is very close to zero.
Pets might have detectable infection (and maybe even symptoms), but if there isn't active replication, they won't shed enough virus to get people sick. I'd put an asterisk on that though, since we don't really know whether pets can spread it to humans. They may be able to.
