Judging from the content on the linked wikipedia page for Herpes Simplex it strikes me as absurd that one would categorize it with the simple cold.
Everyone gets it. It just goes away, often for years. There's no cure. Like colds.
The article doesn't mention, among possible stressors, that spacecraft are always operated at reduced air pressure and high oxygen fraction, and low humidity. The problem is, nobody knows which factors are actually responsible for downregulating immune system activity, because every astronaut gets all of them. A few ought to be variable. Sleep deprivation ought to be entirely avoidable, but NASA cannot quite manage n…
None of your examples are space dependent, and compared to SLS, slightly cheaper.

No, almost 40% of us do not get it. This is not something inevitable. I don't have any family member with the symptoms.

Over 60% of humanity has HSV-1 [1], aka "cold sores" virus. When people "get tested", they generally don't even check for it unless you request it, because it would create unjustified concern. [1] See https://www.who.int/news-room/detail/28-10-2015-globally-an-...
So almost 40% of humanity does not have HSV-1. Astronaut selection is already severe. You don't get selected if you have tuberculosis, diabetes, amputations, or deafness. Once selected, you won't go on the launch if you are sick with the flu. It doesn't seem like HSV-1 needs to be a problem in space. Simply add that to the gigantic list of conditions that prevent space travel. I highly doubt that HSV-1 is anywhere ne…
Leg amputations sound to me like they could be a potential advantage in space.
Is it a circulation thing, or swimming out of a flooding capsule thing?

Speak for yourself, I don't have any form of HSV. One advantage to being a quiet friendless nerd throughout my youth was never catching chickenpox.

Okay, so otherwise qualified and highly skilled people should not be allowed into space due to a potentially minor skin condition. Makes sense. What if they break out with severe acne on the way to the launch pad?
Space travel is like that. At something like $20,000,000 per person, going to a difficult work environment, being picky is important.
I am surprised to see this data, because my impression was that you essentially had to be a physically and mentally flawless human being to go into space.

How do you know? Have you had HSV blood tests?
We're not talking about HPV, which I (and you) very likely have wether we know it or not, without vaccination.
Interesting to me personally because I'd never heard before that HSV-1 reactivation was stress-linked.
It's well known that stress weakens the immune system[1]. So it's not a surprise that stress might encourage dormant infections (such as HSV-1) to enjoy a resurgence. [1] https://www.apa.org/research/action/immune

How do you know? Have you had HSV blood tests?
In my 20s. I suppose it's remotely possible that I contracted HSV since then without ever having any symptoms, but my understanding of HSV is that with all forms the initial infection is obvious so that's quite unlikely.

"Oral herpes infection is mostly asymptomatic, and the majority of people with HSV-1 infection are unaware they are infected." [1]
