Thank
you very much on answer, but I need some explanation why penis-vaginal
fluid contact inside body is risky but outside body is not risky (e.g.
virus lives outside body 1 micro second or it can’t be reproduced in outside environment, or something else).

Sorry for asking for more details
but I am mathematic type and I am always trying to find logical explanation.

Thank you.

Luuk

HIV is fragile and require very specific conditions to transmit it.... INSIDE the body.


external
contact and infection just does not happen in the real work in the 25 years of this epidemic.   If it had, we'd know about it.



but it
doesn't and you won't be the first.   If you have further questions,
i'm sure others here can provide the science, but the science rarely,
if ever, provides people comfort.   It's not the science of it you need
to understand, it's the risk vectors for transmission.  the science will not help you and will only foster additional concerns.

like a hot tub at body temp or a bath?   NO.

Giống như một cái bình nóng ở nhiệt độ cơ thể hay bồn tắm. KHÔNG

Please read the green link i provided 'welcome thread'.


You
get hiv by having unprotected anal or vaginal sex.  those are your risk
factors which is all we discuss here (unless you share needleworks for drug use, which could also be a factor, but you didn't mention that)

Luuk,


It's not just temperature that needs to be right for hiv, it is also pH levels and moisture levels.

Không chỉ là nhiệt độ cần phải thích hợp cho HIV mà cần cả độ pH và độ ẩm


Hiv
is very fragile. It has "plugs" on the surface of its membrane that
must remain undamaged in order to hook into specific receptors on
specific cells before it can successfully transmit itself to a new
host. These plugs and the membrane itself damage very easily. Also, on
the specific cells that hiv needs to bump into in order to infect
aren't found on the outside of the body. They are found in the lining
of the anus and vagina and also the lining of the urethra. Hiv cannot
seek these specific cells out, as it has no means of locomotion. That
is why I say it must "bump into" the right type of cell. You might find this lesson helpful.


Please also make sure you read through the HIV Transmission Lesson


Hiv really is quite difficult to
transmit. Using condoms is all the protection you need against infection.

Hiv thật sự khá khó khăn để lây nhiễm. Sử dụng BCS là tất cả những gì bạn cần để tránh sự lây nhiễm


By
the way, you never mentioned anything specifically that you are worried
about. If you tell us what leads you to think you have been at risk for hiv infection, we will be better placed to help you.
