I wanna know what the latest scientific researches conclude — as I'm sure there must have been some but I couldn't find any on google beyond those "The More You Know" type short articles that are basically in the league of blog posts.
I wish to know about all the data, statistics and figures. For example: "20% of such cases ended in spreading the virus", or, "It is estimated that less than 5% of such cases where one partner showing no symptoms resulted in the passing on of the virus", something like that.
I have consulted 2 medical professionals on HSV-1 (but not on HSV-2), neither gave any actual numbers but both suggested the chances are quite slim and not to the point that serious concerns should be had. However this seems to contradict what the CDC's website: https://www.cdc.gov/std/herpes/stdfact-herpes.htm projects/implies. Once again, the CDC page did not supply any concrete data but instead gave a few rather vague binary possible/impossible style statements which isn't exactly helpful as 1% is also "possible". Inferring from the undertone (which isn't at all objective) of the article it appears that a symptomless spreader event has quite a significant chance of taking place, perhaps larger than 20%?
So just how infectious are they (HSV-1 & 2, respectively)? What are the chances of a symptomless spread?
