Estoy infectado? / Re: Posible infección Sexo oral Insertivo
« Last post by Jim Allen on Yesterday at 06:02:59 pm »
Estas preocupando innecesari y su problema es emocional no VIH.

No hay riesgo de vih, no veo razón para realizar el test a menos que hayas tenido otros encuentros sexuales que no hayas mencionado aquí.

Como eres sexualmente activo, hágase la prueba para detectar el VIH y las ITS por lo menos una vez al año.

el VIH no puede transmitirse a través de un condón intacto.

Adelante con su vida y como eres sexualmente activo, hágase la prueba para detectar el VIH y las ITS por lo menos una vez al año.

Y además prueba negativa de mi pareja

Él se hace chequeos constantes, hoy llegaron sus resultados negativos.

Totalmente irrelevante

Tengo mucho miedo Jim, estoy muy deprimido

You have had 14 negative HIV tests when Zero where needed and still think you got HIV from a handjob.

You don't understand, as your left testical could drop off and your right arm it would not change that you had no HIV risk to start with from the handjob. Now, let say you tested positive next week it would still not be from the handjob, it would be from your real, recent and ongoing risks like the condomless intercourse!

Now to be very clear there is nobody in the I just tested positive section that has tested positive without having a real exposure or without having ongoing exposures and nobody outside the testing timelines post a risk in the manner that you are suggesting. Let's just be very clear on that.

I do know and have heard wild stories, we all have from time to time, and if you have been reading stories online and mistaking them to be facts, no wonder you can't move on with your life. I've done this for a while and have had people claim to have acquired HIV after contact with Aliens from outer-space, toilet seats, door handles, handshakes, eating food and drink ect https://www.avert.org/news/5-weirdest-hiv-transmission-myths-ever

It's okay I understand they need a story for themselves, it's the old good AIDS vs bad AIDS thinking, but thankfully these stories are just stories, not facts and, there are many reasons why someone would rather not admit to exposure or simply incorrectly dismiss a real risk without realizing it.

Factoring into stories is that being newly diagnosed is difficult enough time on its own. For some, it's a time of struggling with a deep fear of HIV stigma, social judgment, legal concerns, self-stigma and things like sexuality or facing one's sexual orientation, religion, family, etc. 

Finally, as mentioned you are getting a ban, it's out of kindness as this is not helping you move on and neither is the merry go round of testing. Please consider seeking professional support to help you overcome this phobia.

Best, Jim

Asides from my experience & knowledge below is a small collection of data on stories & testing for you to consider.


STI Risk Perception in the British Population and How It Relates to Sexual Behaviour and STI Healthcare Use: Findings From a Cross-sectional Survey (Natsal-3)

We have identified falsely optimistic views of personal STI risk among a substantial proportion of those at risk of STIs in the British population, which could have a negative impact on efforts to promote safe sex and STI testing, and the control of STIs.

Among those classed as having ‘unsafe sex’ in the past year (comprising approximately 1 in 5 sexually-active 16–44-year-olds), 39.2% of men and 51.0% of women rated themselves as not at all at risk of STIs


Underreporting in HIV-Related High-Risk Behaviors: Comparing the Results of Multiple Data Collection Methods in a Behavioral Survey of Prisoners in Iran

Participants reported more sexual contact in prison for their friends than they did for themselves. In men, NSU provided lower estimates than direct questioning, whereas in women NSU estimates were higher. Different data collection methods provide different estimates and collectively offer a more comprehensive picture of HIV-related risk behaviors in prisons.


Socially desirability response bias and other factors that may influence self-reports of substance use and HIV risk behaviors: A qualitative study of drug users in Vietnam

The accuracy of self-report data may be marred by a range of cognitive and motivational biases, including social desirability response bias

Self-perceived risk of STIs in a population-based study of Scandinavian women

Subjective perception of risk for STI was associated with women’s current risk-taking behaviours, indicating women generally are able to assess their risks for STIs. However, a considerable proportion of women with multiple new partners in the last 6 months and no condom use still considered themselves at no/low risk for STI.


Social desirability bias and underreporting of HIV risk behaviors are significant challenges to the accurate evaluation of HIV prevention programs for orphans and vulnerable children (OVC) in sub-Saharan Africa


Non-disclosed men who have sex with men in UK HIV transmission networks: phylogenetic analysis of surveillance data

Jim: In short they analysed the genetic code of the virus from HIV-positive people and came to the conclusion that some of the self-reported heterosexual mens HIV was more than likely actually non-disclosed MSM.

Is Patient-Reported Exposure a Reliable Indicator for Anogenital Gonorrhea and Chlamydia Screening in Young Black Men Who Have Sex With Men?

Among 485 young black men who have sex with men recruited in Jackson, MS, 90-day anal sexual exposure significantly predicted rectal infection, but 19.4% of rectal infections would have been missed among men denying receptive anal sex. Reports of consistent condom use were associated with lower infection rates only in men reporting insertive anal sex.

Could misreporting of condom use explain the observed association between injectable hormonal contraceptives and HIV acquisition risk?

Jim - Not a conclusive or in depth study but under the study participants it did find: 9 out of every 20 sex acts reported with condoms are actually unprotected


Rollins School of Public Health, Emory University, and the Kensington Research Institute, Silver Spring, MD 20910, USA https://www.ncbi.nlm.nih.gov/pubmed/14655794

"At risk" women who think that they have no chance of getting HIV: self-assessed perceived risks.

more than one-half of the "no perceived risk of HIV" sample had engaged in at least one risky practice during the preceding year and more than one-quarter had engaged in at least two such behaviors

The Validity of Teens’ and Young Adults’ Self-reported Condom Use

A significant degree of discordance between self-reports of consistent condom use and YcPCR positivity was observed. Several rival explanations for the observed discordance exist, including (1) teens and young adults inaccurately reported condom use; (2) teens and young adults used condoms consistently but
used them incorrectly, resulting in user error; and (3) teens and young adults responded with socially desirable answers

BMC Public Health 2007

Analyses of data from the Demographic and Health Surveys, Sexual Behaviour Surveys and from other countries show a similar pattern indicating under-reporting
It is probable that as HIV campaigns encouraging delayed sexual debut and abstinence before marriage reach the population, people will report behaviour
assumed to be more socially desirable.

there are some signs of differential reporting bias in our study. We found that controlling for less risky sexual behaviour substantially reduced the association between HIV and survey time among urban men, but less so among women; this may suggest that self-reports from men about sexual behaviour are more reliable. Studies suggest that respondents, especially women, tend to under-report the number of lifetime sexual partners . Therefore, analyses of associations with, and changes in, self-reported sexual behaviour should be interpreted with caution.


Self-presentation bias (wishing to be viewed in a positive light) may result in patients underreporting behaviors they perceive to be stigmatizing

Approximately a third of the men in the sample reported that they did not disclose all of their risk behaviors to the HIV counselor during the face-to-face risk assessment. These results echo similar studies of risk disclosure to medical providers

Taylor, D., Durigon, M., Davis, H., Archibald, C., Konrad, B., Coombs, D., et al. (2015). Probability of a false-negative HIV antibody test result during the window period: a tool for pre- and post-test counselling. Int. J. STD AIDS 26, 215–224. doi: 10.1177/0956462414542987

Patients typically want accurate test results as soon as possible while clinicians prefer to wait until the probability of a false-negative is virtually nil. This review summarizes the median window periods for third-generation antibody and fourth-generation HIV tests and provides the probability of a false-negative result for various days post-exposure. Data were extracted from published seroconversion panels. The median (interquartile range) window period for third-generation tests was 22 days (19-25) and 18 days (16-24) for fourth-generation tests. The probability of a false-negative result is 0.01 at 80 days' post-exposure for third-generation tests and at 42 days for fourth-generation tests.

Rosenberg NE, Kamanga G, Phiri S, et al. Detection of acute HIV infection: a field evaluation of the determine(R) HIV-1/2 Ag/Ab combo test. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3318673/

Results. Of the participants 838 were HIV negative, 163 had established HIV infection, and 8 had acute HIV infection. For detecting acute HIV infection, the antigen portion had a sensitivity of 0.000 and a specificity of 0.983. For detecting established HIV infection, the antibody portion had a sensitivity of 0.994 and a specificity of 0.992.

Conclusions. Combo RT displayed excellent performance for detecting established HIV infection and poor performance for detecting acute HIV infection. In this setting, Combo RT is no more useful than current algorithms.

In total, 953 people underwent HIV testing. HIV antibody (Ab) prevalence was 1.8% (17/953). Four false positive rapid tests were identified: two antibody and two p24 antigen (Ag) reactions. Of participants diagnosed as HIV Ab positive, 2/17 (12%) were recent seroconverters based on clinical history and HIV antibody avidity test results. However, none of these were detected by the p24 antigen component of the rapid test kit. There were no other true positive p24 Ag tests.

CDC recently published research findings that estimate the window period for 20 U.S. Food and Drug Administration (FDA)-approved HIV tests. The study showed that laboratory testing using antigen/antibody tests detects HIV infection sooner than other available tests that detect only antibodies. If a person gets a laboratory-based antigen/antibody test on blood plasma less than 45 days after a possible HIV exposure and the result is negative, follow-up testing can begin 45 days after the possible HIV exposure. For all other tests, CDC recommends testing again at least 90 days after exposure to be sure that a negative test result is accurate.

Recommendations (Grade 1A)

• Clinic policies and patient information regarding the HIV test window period should be based on 99th percentile estimates; where a test is undertaken sooner than this time interval, window period data should be used to counsel patients as to the likelihood of a false-negative result.

• Fourth-generation laboratory tests reliably exclude HIV by 45 days post-exposure, and this should be the window period applied when utilising these tests.

• Third-generation laboratory tests reliably exclude HIV by 2 months post-exposure, and this should be the window period applied when utilising these tests.

• POCTs reliably exclude HIV by 90 days post-exposure, and this should be the window period applied when utilising these tests.

2015 WHO http://apps.who.int/iris/bitstream/handle/10665/179870/9789241508926_eng.pdf;jsessionid=1F192FECF734A0DE7E2520864984AE63?sequence=1
In many settings post-test counselling messages recommend that all people who have a
non-reactive (HIV-negative) test result should return for retesting to rule out acute
infection that is too early for the test to detect. However, retesting is needed only for HIV-negative individuals who report recent or ongoing risk of exposure. For most people who test HIV-negative, additional retesting to rule out being in the window period is not necessary and may waste resources.

Please don’t ban me, I didn’t see that but until I replied already sorry.
Just regarding my test results are they fully conclusive regardless of my zero risk exposure.
I won’t bother you again until I’ve spoken with a physiologist.
Thx again for you help.
Thx Jim
I understand what you are saying but physiological I cannot accept all these physical symptoms.
Also reading the I just turned Poz forum there are example’s of when 4th Gen testing has given false negatives.
I’m going to ask for medication to help me try and get over this.
Jim can you just tell me with the testing I’ve done is there anything that would give so many false negatives, I’m reading people are saying 6 months is conclusive.

Have you ever seen anyone with my testing turn positive after?

I appreciate how tedious I must be so I’m really sorry but I’m in the worst place.
Antibiotics would not change the window period for HIV testing, it also does not matter if it did since you had no HIV exposure, no HIV risk!

Now I am sorry that you are feeling unwell but it has nothing whatsoever to do with HIV from the concerning incident.  Like I said I am not willing to pretend as that would be a disservice.

Instead of the merry go round of pointless testing over nothing, I would recommend instead you consider speaking to a therapist to help you cope with these irrational fears/phobia and guilt prehaps.

Read the below again and if you continue to post about this it will lead to a ban to encourage you to seek professional mental health support.

Lets recap.

You had no HIV risk from the handjob, no need to test over this as HIV can't be acquired that way and we're not going to pretend it was an HIV risk. It lacks all the biological and environmental conditions needed.

So relax and move on with your life. Regarding your wife, that's your ongoing risk and as you are sexually active make sure to test at least yearly and more frequently if you engage in condomless intercourse.

Finally, I am sorry that you have been stressing about and feeling unwell, I hope you feel better soon. Work with your doctor and treat whatever is making you feel unwell.
