[Question #4986] Herpes Transmission

Thanks for taking the time to review my questions. I'm wondering about herpes transmission and my specific questions are as follows:

1) If someone gets cold sores, could you get herpes from them if they spit onto your face or even into your mouth and eyes while talking to them?

2) If herpes can be contracted by being spit on, would it affect the possibility of transmission if the person had HSV 1 or 2?

3) And if transmission is possible from someone spitting onto your face during conversation, would it still be possible to contract herpes if the person had oral herpes but did not have a cold sore at the specific time when they spit onto your face?

1.  No.  It takes a significant amount of virus to infect another person and I don't believe there is a circumstance where you someone cold spit enough into your face or mouth while simply talking to infect someone. 
2.  See #1, please
3.  See #1 please.

This is simply not a risk for transmission.  Kissing someone passionately who is infected with the cold sore virus?  Yes.  Spitting, no.

Thanks for answering my questions! With so much random and often incorrect info on the internet, I cannot tell you how nice it is to be able to ask an expert!!!

What about stuff like drinks and silverware? Although I can't remember where I read it, I read somewhere online that one of the herpes viruses (I think it was the one more commonly associated with oral herpes) can live longer outside the body than the other. So with that virus, becoming infected by doing something like using the same fork as someone infected or sharing a drink or doing something similar where there is not direct skin-to-skin contact. Are these types of encounters actual risks for contracting the virus from someone who has oral herpes but doesn't have a cold sore at the time? If this sort of contact is a risk, does it affect the risk level if it is HSV 1 or 2?

Also, years and years ago, someone told me that their brother had touched what he thought was a canker sore and then touched his eye. Apparently though it wasn't a canker sore. I honestly can't remember if the person told me it was a herpes sore, but the virus somehow caused an infection in the brother's brain and he ended up dying. I am sorry if this seems like a lot of speculation and also one of those freakish situations that even if possible are extremely unlikely. However, I've always wondered if something like this happening with a cold sore, or any sore caused by the herpes virus, is realistic. If you touched a herpes sore and then touched your eye, could it end up causing some kind of brain infection? Or, could the virus cause some kind of eye problems?

There are no documented cases of transmission of HSV via drinks and silverware.  I do caution people against sharing lip gloss or lipstick when cold sores are present.  And sex toys.
  Canker sores are not caused by herpes and herpes encephalitis is very rare condition (about 1500 cases per year) and is usually associated with HSV 1, not HSV 2.  If someone acquired herpes in the eye, it would not cause encephalitis but rather ocular herpes, herpes of the eye.

Thank you very much for all the information!

Can you contract herpes from sharing a hot tub with someone who has herpes or is having an outbreak? I read online that this is possible, although I can't remember if the scenario outlined specified if the person with herpes was having a current outbreak or not.

Should you get tested for herpes even if you never had an outbreak? I've been tested for other STIs but the testing didn't include herpes. I'm on the fence about getting tested because I've never had an outbreak and if I tested positive, I wouldn't even know what to do with the information.

Does a herpes outbreak ever resemble a pimple or other skin blemish? I always thought that herpes presented as an open sore but I've read online that this is not always the case. If herpes can resemble a pimple or other skin blemish, how can you tell the difference?

No, not unless you are having sex in the hot tub with someone who has HSV 2. 
It's your call about whether to get tested or not.  We experts on this forum do not agree about this so you an imagine that there are a variety of opinions about this.  If you were positive, you could daily antiviral medicine to reduce the risk of infecting partners and also use condoms - condoms reduce the risk of transmission by 96%.  And you would be obliged to disclose your infection to future partners to allow them to make the decision about whether to take the risk of becoming infected.  In thinking about whether to get tested or not, factors to take into consideration would be the number of lifetime sex partners, how often you have used condoms and also how much you want to know whether you have any transmissible to a partner.  If you do test, use only the IgG test, never IgM and just so you know, the very best test is the herpes western blot, done only at the University of Washington
