[Question #3867] HPV Transfer from ultrasoundqdoppler device

32 months ago
A few days ago i was diagnosed with an ultrasound/doppler device in a private labratory to check the flood flow to my penis.( thats what this specific labratory do all the time) The device was attached to my penis a few times in different locations and using a special GEL . The device was not clean ,without protection of any kind, and the operator did not clean it - for sure. the last guy that was checked with the device did it about 1hr before me. What are the odds to get infected with HPV with that procedure?and why?  there are mixed opinions about catching HPV from fomites/sex toys/inanimate objects.

thanks, very nervous.

Welcome to the Forum.  I'll be glad to comment but, before I do, I must comment that it would be most unusual for a medical device used to take measurements from any cutaneous surface to not be cleaned between uses.  Typically, ultrasound probes are also used with coverings which also reduce the chance of transmission.  If after asking you find that the device used on you was not cleaned between patients I would be troubled.

that said however, although HPV has been demonstrated to be present in environmental surfaces for hours after being contaminated, transmission from such surfaces and devices has never been documented and is not something that I would worry about.  This topic has been studied and despite such studies, once again I'll point out that transmission through contact with medical devices or surfaces has not been ever found.

I would not worry about your risk for HPV from your contact with the ultrasound device.  I hope my reassurance is helpful to you. EWH

A doctor offered me an HPV PCR test and said that the one  he is using is very relieble even after just 24hours. right now 72 hr have passed.
 To do the test he takes cultures from my mouth, anus, and penis and sends to labratory. It is expensive-250$ .

1.Do you think i should do to test? I have a girlfriend and i afraid to infect her.

2.Are there any other STD’S i should be afraid of because of my speciefic case? other than hpv? 

3.why some doctors believe that it is possible to get hpv from a used towel if those kind of infections never been documented? I saw that you talked before about hpv dna and not virus in whole.... 

4.is my case different from used sex toys for example? (As far as i know it is quite possible to get hpv from a used vibrator) 

Thank you.

There are no FDA approved tests for HPV available in the U.S.  Many laboratories have and offer them but a more important question for you to consider is what if you were found to have HPV at any particular site.  Expert advice would be to simply observe prospectively for signs of lesions.  Treatment would not be warranted.    Further, should you turn out to have HPV, odds are that you acquired it sexually, not from the ultrasound device.  If you look at 4-5 posts from other clients regarding HPV you will see that the data we cite indicates that nearly all sexually active persons acquire HPV during their lives, that well over 90% of those infections resolve spontaneously without therapy and that less than 1% go on to progress to cancer.  HPV is part of what happens among sexually active persons and is a nuisance which is preventable in younger persons by the vaccine and is of little consequence for persons who see their health care providers on a regular basis.

In answer to your specific questions:
1.Do you think i should do to test? I have a girlfriend and i afraid to infect her.
I recommend against testing.  Depending on her age your GF may have been vaccinated and is not at risk.  Further, if she has had other sexual partners and has not been vaccinated, then odds are she already has HPV (just as you do if you have had other partners).

2.Are there any other STD’S i should be afraid of because of my speciefic case? other than hpv? 
No, and I would urge you not to worry about HPV either.

3.why some doctors believe that it is possible to get hpv from a used towel if those kind of infections never been documented? I saw that you talked before about hpv dna and not virus in whole.... 
Those doctors are misinformed.

4.is my case different from used sex toys for example? (As far as i know it is quite possible to get hpv from a used vibrator) 
Whether or not HPV is transmitted by shared sex toys or not is not clear.  If transmission were to occur, it would be in situations in which the toys were shared immediately without cleaning.  Your situation is not like that.

My advice:
1.  Do not worry about this event.
2.  Do not worry about HPV
3.  Look at 4-5 other posts about HPV on this site, you will see that your concerns are widely shared but that they are not a problem for you, your health, or your partner's heath.
4.  Stay off the internet. The information there is often taken out of context, out of date or just plain wrong.  EWH

Question about the HPV PCR - is it possible that after a few days from contact , the test will find dna of hpv on my skin and become Positive while i actully did not get infected with HPV at all ?

I mean - does the teat check for active infections or just dna hpa cells? 

Thanks

Absolutely.  A PCR test could detect DNA which was present but not going to go on to cause infection.  The further out one is from the contact, the less likely it is to happen but it certainly could and does happen.  The presence of DNA does not necessarily mean that an active infection is present.

I'll repeat my advice from above.  I really think you are overthinking these concerns and would not worry.  I hope you will do that.  This is my 3rd reply to your questions  This, as per Forum Guidelines, this thread will be closed without further answers from me in a few hours.  Take care.  Please don't worry.  EWH
