mucous membranes

[helpmeplease4040]

hi doctor,
i wanted to ask a question for my knowledge and everybody else's on this forum
and i had a lot of exposures with blood on my mucous membrane


just wanted to know the difference between mucous membrane and other skin of the body
i know if hiv positive fresh blood gets on any skin of our body it cannot enter as skin will protect it but what about mucous membrane like nose penis lips etc etc
can blood seep in the mucous membrane?



if  fresh hiv positive blood touches or is poured on any mucous membrane of your body does it pose a risk and can blood seep in mucous membranes ?
i mean touching blood or pouring blood on mucous membrane and not injecting

You are repeating yourself and wasting your time:

1.  Correct.
2.  HIV is not spread by frottage, with or without blood as has been said on this Forum inumerable times.

hello doctor,
thanks a lot for your reply and i am sure that i cannot get hiv from bloody nose exposure.
my question was for my knowledge and a lot of exposures where mucous membrane got in touch with blood like frottage and all in the past.

my only and last question is

1) hiv cannot seep in mucous membranes like it cannot seep in any other normal skin when fresh  hiv positive blood is poured in on mucous membranes?

2) if penis is rubbed on vagina (frottage) and hiv positive menstrual blood gets on the penis even then there is no risk? if not why?

pls answer the questions doctor and i hope i am not repeating myself and feel sorry if i am.
thanks and regards doctor
god bless you

I note that because of your continuing unwarranted concerns about a most unlikely nasal "exposure" Dr. Handsfield terminated your earlier interchange.  I will briefly  try to address your question but to be honest, my assessment is not your "risk" but your unwarranted anxiety.  Asking further, repetitive questions will not change this.

The entire body is covered with what are called epithelial cells.  Both our skin and mucous membranes are composed of epithelial cells and the structure of these surfaces at different parts of the body and with different mucous membrane surfaces varies from site to site.  In general mucous membranes have more glandular tissue that epithelial skin surfaces- these help to keep the areas moist.  HIV does not pass through intact mucous membranes.  HIV is sexually transmitted with the friction and minor trauma associated with normal sexual activity act to cause minor breaks in the mucous membrane surfaces through which HIV, when introduced in high concentrations sometimes enters to cause infections.  The mucous membranes of the mouth are very different from the mucous membranes of the nose.


Finally, although you did not ask it directly, I will reiterate what Dr. Handsfield has already told you- there is no risk of HIV from having been examined in a doctor’s office for a bloody nose.  I will not debate this or entertain and "but what if...." questions - no risk.

I hope this helps address your question and will allow you to move forward from your position of unwarranted concern. EWH
