I said “visible effects” which is different than detecting a virus in human body. That mean pre-symptomatic transmission. I am not up to date with latest research but it seemed to be that SARS-CoV-2 is a virus that can be transmitted before symptoms onset. Regarding replication without being detected but also increased lethality this you might be right that doing the math maybe the hypothesis I present seems far fetched. Still I guess that a slight bump in mortality will create a lot of deaths due to its transmission. Of course like I said I am just expressing an opinion that might be very wrong.
