|Infection viral load threshold
Apr 11, 2001
Hi, May I know what's the number of virus particles required to enter the body for an infection to take place? I know this varies, but is there a range?

I am not sure we can answer that question specifically. We know that in at least one study, that sexual transmission did not occur if a person had a viral load of < 1500/ml of blood plasma. One could extrapolate the potential volume and viral load in genital fluid and potentially come up with a number.
