Hiv evolution

Common Questions and Answers about Hiv evolution


Avatar m tn I also appreciate reading the professional and nonjudgmental advice you give others with HIV-related questions. I noticed that over time, and this is just my perception, that yours and the other physicians' opinions on certain issues have varied somewhat; i.e., several years ago you advised that oral sex was "low risk"(advising against engaging in oral sex with a known hiv-infected individual) but more recently referred to it as "no risk".
Avatar n tn Where to start with a post like this? My god. "I am sure a lot of you older fellas remember the 1970's like it was yesterday...promiscuous, unprotected sex with many women, experimentations with mind-expanding drugs in a non-consequential environment, etc. Get an STD in the 70's, and a shot of Penicillin was the cure." The penicillin is helpful for the bacteria-based infections only. Herpes was around in the 1970s.
Avatar m tn But I think you failed to understand some basic aspects of HIV evolution and diagnosis. The genetic and antigenic differences between strains are great in one sense, but the core genes and the proteins for which they code are in fact quite stable. There is no material difference across strains for p24, gp120, or gp41, the main antigens used as the basis for the routine HIV antibody tests.
Avatar m tn The fact that i have 3 mouth ulcers now does that mean a slow evolution of HIV????? pLEASE I AM AFRAID!!!!!!!!!!!!!!!!!!!!!!!!!
Avatar n tn PCR-DNA Tests Neither the Abbott RealTime nor the Roche COBAS AmpliPrep/COBAS TaqMan HIV-1 assay is intended to be used as a donor screening test for HIV-1 or as a diagnostic test to confirm the presence of HIV-1 infection.
Avatar n tn Most other websites indicate that a negative HIV test at 12 weeks is conclusive regardless of vintage. You are obviously HIV negative.
Avatar m tn Second, it is pretty much impossible to catch HIV by unprotected vaginal sex, and the risk of HIV transmission is not significantly higher when infected women are menstruating. Menstrual blood on the outside of a condom doesn't mean anything important. As for symptoms, perhaps the single piece of advice we give most frequently on this forum is that symptoms are virtually never useful in judging whether or not someone has HIV.
1024580 tn?1331577721 Romero and others, in their article describing an excellent and diligent long term study failed to identify any risk at all in transfer of HIV from an HIV positive to an HIV negative partner through oral sex. In total 19000 episodes of oral sex were documented amongst 135 heterosexual couples over ten years and in 34% of these episodes the HIV positive male ejaculated into the HIV negative females' mouth. (Romero J et al.
Avatar m tn 3)Since the new generation tests have been introduced have their been any cases of people going past 6 to 8 weeks for HIV other than people on HIV antiviral drugs, PEP, chemo etc. I did read about a conference that had 300 doctors that specilized in HIV that didn't put there hand up to this question about people testing positive after 6-8weeks. It there anything in medical journals that you have read or heard of that might suggest some people have gone past this period of 6 to 8 weeks?.
Avatar n tn gag, pol and env. They found that among the mutations randomly affecting the genome as a whole, those which influence the genes essential for viral survival and multiplication appear to be systematically selected against (negative selection).
Avatar m tn hiv and ks are different things you do not have hiv,,,and that the case of this forum ks evolution dependens on many factor ,, its true there some kind of cofactor with hiv ,, but thats not the case of this forum moreover some mediterranean etnics suffer ks more than others etc whatever the case NOTHING to worry about have a good day
96938 tn?1189803458 Thx, I sent a letter both to the general email inquiry address and to head of the department which deals with HIV. Of course Hepatitis is not mentioned anywhere under any of the departments, but that should be of no surprise to most of us here.
1494472 tn?1299614037 Dear all: I had skin with skin contact with a hiv+ guy 4 weeks ago. NO penetration, he just gave me oral sex Today is one week sore and itching Its clear I do have hsv.. I´ll visit an infectologyst on Monday Im hiv negative QUESTION: Could I have had hsv-8 and then sarcoma kaposis? Whats that about type 4- 5-6- 7? Or I just have to check types 1 and 2?
Avatar n tn Hence Different Assays for Viral load HIV-1 and HIV-2. Apparently It's not easy to Get Viral load tests for HIV-2 as it is for 1. Tests have to be programmed to Know what to look for. I'm Guessing PCR is More Accurate as mutation would have to affect more than the antigenic sites, so it would become a totally different animal. Reverse transcriptase is an enzyme, that would be positive anyway.
Avatar m tn Still doctors I have seen believe this is not a sing of emergency, and no need to further evolution. What do you think, and recommend? Tests I have done ( I repeated below tests several times): CBC: WBC (Low) 3.0 range 4-11 Absolute Neutrophil (low) 1.5 range 1.6-9.3 Protein Total (High) 8.
Avatar n tn 4)You currently suggest 6-8wk testing post exposure. Is this what's been recommended by HIV experts to people as well as med students?. I found out that my wife has been with another man that has been HIV positive and I have had unprotected sex with her not knowing this. I am trying to move on and would like to know as being tested if I am absolutely in the clear without any worry in the future. Hence the questions at the start. I am worried about being positive in a years time or later.
Avatar f tn This lack of phenotypic innovation over an extremely long period of divergent evolution demonstrates, perhaps, how the evolution of HCV is shaped and constrained entirely by its close adaptation to the particular ecological niche it inhabits, the human liver. HCV genetic diversity and genotypes Genetic variability of HCV exists at several different levels.
634590 tn?1293777693 All of these viruses that are showing up such as the swine flu, HIV, SARS, avian flu etc. and including HepC were passed on to us by the animal world. When you have 10 minutes you can watch this video on youpoop and it will tell you the whole fret SARS, avian flu, swine flu ... each virus outbreak raises the question: What can be done?
Avatar n tn As far as hiv, since its evolution there never been even one case of infection through intact condom.
Avatar n tn I got my first testing of HIV after 14 months by HIV-Biome Tridot Kit on 16 Jan 2008.It was NEGATIVE. The test was conducted in a private hospital in Bhubaneswar. But I thought the test may be wrong. Again I got my 2nd test after 22 months on 21 September 2008 for HIV-1 & HIV-2 Antibody and pb-24 antigen test which was also NEGATIVE. The sample was collected by Dr Lal Franchise in Bhubaneswar and test was conducted in Dr Lal Lab in New Delhi.
Avatar n tn I doubt that multivitmans would change the bateria of chlamydia. Normally it is from common evolution that a bacteria or virus will mutate.
553878 tn?1226510894 The lack of public knowledge. testing, and misconceptions are unbelievable. Hell herpes, warts and vaginal itch get more publicity (for lack of a better word). From what I ascertain we are just the vanguard of a whirl wind yet to come. Powers that be know the stats. Is it because its"mostly an I.V. drug user thing" like they did with HIV for decades. On that note does and to what extent is the government involved in funding for research.
Avatar m tn Teak, if you're available... First, I'll apologize if incomplete parts of this question were sent to you prior to this. My computer has an issue these days and has been sending off partial messages prematurely. A couple of seemingly contradictory statements by the immensely knowledgeable Dr. Handsfield have a few of us confused and hoping you can clarify what you would know his specific position to be regarding this oral sex issue. In May/2011, a poster referenced this comment by Dr.
Avatar n tn I had absolutely no concerns over the bj because I read a risk chart before the event which didnt list HIV (or any other non-treatable disease)as a risk when getting a bj. (San Fran. health dept. / also other sites have stated clearly there is no risk at all for the insertive partner) BUT to my horror..the CDC site says there are documented cases! Then I revisited Medhelp site and saw DR HHH quoting a 1 in 20000 risk! I thought he used to say no risk?
Avatar m tn Last night I had unprotected sex with a female who tested HIV positive some years ago. Oral sex and vaginal pentration and kissing. She told me that her HIV is dormant and that while I may want to use protection, it's more difficult to contract it from a female. She also stated that her HIV is sow low as to be now undetectable. I need information on the likelihood that I contracted it last night, what I need to do to protect myself and what I don't have to worry about.
Avatar m tn Time later I found what I thought was just another bump located at the base of my penis, on the upper side, and tried to squeeze it but nothing came out, I never worried about it, I have never worried until now about STD's I have tested negatived for HIV three times in the last 5 years, and gave it little importance until recently.
Avatar m tn In general, the STDs and the bacteria, viruses, and other organisms that cause them evolved in parallel with human evolution in a way that makes very intimate contact a requirement for transmission. In general, that requires insertive sex -- i.e. a penis inside another person's vagina, rectum, or mouth. Although rare transmissions occur through genital apposition without penetration, it is very uncommon.
Avatar m tn I'm not sure if these remaining pains actually have to do with nodal swelling or ARS or HIV, but they of course have me a little worried since they all showed up around the 4th week after my exposure. However, by this time all of the other possible ARS symptoms, like my rash and sore throat had already began to go away. My main question is, 1.
Avatar m tn He took all the tests for std's and hiv. I went to the free clinic and took another round of std medication, the pills and shot. A quick blood hiv test showed negative. Two weeks later, the urologist said I had no std's and no hiv. Its almost three months now. Despite the urologist telling me I don't need to, I am going to get my tests again. I am living with guilt and fear. I come to sites like Medhelp for guidance and honest answers.
