Hiv transmission via frottage and rubbing genitals? Especially if female is releasing a lot of vaginal fluids, & tip of the penis also rubbed

Hiv transmission via frottage and rubbing genitals? Especially if female is releasing a lot of vaginal fluids, & tip of the penis also rubbed

Low risk: In general, genital rubbing and frottage would not be a risk factor for HIV transmission. However, exposure to vaginal fluids which can contain and transmit HIV does pose a risk, especially in the presence of "broken genital skin" which may or may not be evident to the naked eye. ...Read more

Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

Is dry skin a possible route for HIV transmission from infected blood on a object to dry skin on a persons hand?

Is dry skin a possible route for HIV transmission from infected blood on a object to dry skin on a persons hand?

Only if a cut: In general, contact via skin with HIV+ blood or fluids is relatively lower risk if the skin is intact, whether dry or not. However, as dry skin has the possibility of having more microscopic wounds than other healthier skin, the HIV could have an easier portal of entry. If you are worried you contracted HIV you should go to your doctor for testing and post-exposure medications immediately. ...Read more

I am worried about possible HIV transmission?

HIV: Transmission of this virus occurs only with intimate contact, either sexually or through needle sharing or blood or organ exchange. Make sure you have only protected sex. Ideally you might want to have a new sexual partner tested and not have sex with them until you are sure they are negative. Condoms are very effective. Several wives of my HIV patients have been negative for years. ...Read more

Hiv must be caused by transmission and transmission only. Is that right?

Hiv must be caused by transmission and transmission only. Is that right?

Yes.: Hiv (the virus that causes aids) is spread from person to person by sharing needles or by exchange of body fluids in intimate acts like oral/vaginal/anal intercourse. Hiv does not arise 'spontaneously' and is acquired by interactions with other people who are already infected with hiv. Do not share needles and always use a latex condom with spermicide to diminish risk of transmission. ...Read more

I've read that female to. Male HIV transmission is much lower than male to female transmission why is this true?

I've read that female to. Male HIV transmission is much lower than male to female transmission why is this true?

Skin vs. Mucosa: That's true in the us, mainly because the penis is covered almost entirely with uninfectable skin, whereas the vagina covered with infectable mucous membrane. Things that increase the risk of female to male transmission include genital ulcers or lack of circumcision in the male partner. ...Read more

Why are studies so quick to dismiss the transmission of HIV environmentally? Have there ever been studies on the survival outside? Plz show me links.

Why are studies so quick to dismiss the transmission of HIV environmentally? Have there ever been studies on the survival outside? Plz show me links.

No reason for fear: You describe a curious fact -- a theoretical risk that plays out in the real world as no risk. You've put yourself in the same situation as a woman who's afraid to swim in a public pool because there may be a live sperm that will make her pregnant. It just doesn't happen, and people aren't getting HIV by touching the xerox machine. Stop doing this to yourself and get on with your life. ...Read more

Can semen be a way of transmission of HIV and hepatitis?

Can semen be a way of transmission of HIV and hepatitis?

Yes.: Male ejaculate (semen) can carry viral infections such as HIV and viral hepatitis. Always using a latex condom and a spermicidal / viracidal lubricant can help to diminish the chance of acquiring a viral sexually transmitted disease. Hope that this helps. ...Read more

Immediate: Your should check immediate test to see your current status prior to this potential source.

It is better to see infectious disease physician to better understand this seroconversion, and your chance to get this infection. ...Read more

What is the risk from open wound to wound contact in terms of HIV transmission?

What is the risk from open wound to wound contact in terms of HIV transmission?

Moist transmission: Hiv virus is best transmitted when there is contact between someone with the disease who has an open wound or whose moist mucous membranes (mouth, penis, vagina, anus) comes in direct contact with some one elses open wound or moist mucous membranes. The virus must stay in a moist environment to be transmitted. Toilet seats, door knobs, etc. Will not allow transmission.A moist environment is key! ...Read more

If masseuse have others' semen on her hand n gave me a handjob, is that HIV transmission?

Can having a low HIV viral load lower the likelihood of transmission by a lot?

Can having a low HIV viral load lower the likelihood of transmission by a lot?

Yes!: Yes, by a lot. A large clinical trial showed that treating an infected person reduces the risk of transmission to a negative partner by 96%. If the positive partner has an undetectable viral load, the benefit is probably close to 100%. We still recommend condoms though, since you don't get your viral load checked every day. ...Read more

Can protected sex hold a risk of HIV transmission to a man? Can a man be infected with HIV through blowjob?

Possibly: Yes to both. But it is an exceedingly rare occurrence. Open sores in the mouth would be required and condoms are quoted to bring something along the lines of 99% percent effective. But remember if you fall into that 1% or even. 1% it's a 100% for you. Be safe. ...Read more

Dr accidentally re-used a thermometer without the plastic cover (noticed afterward), it this a risk for HIV transmission?? Oral thermometer

No risk, no worry: HIV is not transmitted by oral contact. For example, kissing carries no risk, and neither does oral sex (or so little that there are no proved cases of HIV transmission mouth to penis). So even if a previous patient using the thermometer had HIV, you would not be at risk. Maybe very small risk for more common viruses, like colds and influenza. But not HIV. ...Read more

Can nipple biting be a source of HIV transmission?

Can nipple biting be a source of HIV transmission?

Unlikely: Transmission of HIV through saliva is highly unlikely, since the enzymes kill the virus. If the person doing the biting draws blood and they are bleeding and have HIV disease, this is conceivable, but very improbable. ...Read more

Can prednisone for eczema increase the risk of transmission for hiv?

Repeated Question: Not sure why the previous answer was not adequate. Do you mean as someone who is contagious and you wonder if Prednisone will increase the contagiousness? Or will being on Prednisone make one more likely to get hiv? In either way if there is no high risk activity then Prednisone does not increase the risk. ...Read more

Can having a low HIV viral load actually prevent some transmission?

Let me clarify: It's not the fact that a low viral load prevents transmission it's that a low viral load has less of a chance of being transmitted as an infection. In simple terms it's all about the type of exposure, h the duration of the exposure, and the intensity of the viral load that helps determine transmissibility. ...Read more
