Study: HIV Becoming Less Deadly, Less Infectious
An anonymous reader writes: A new study (abstract) from Oxford University shows HIV is weakening as it evolves in response to our immune system. When the virus encounters somebody with a particularly strong immune system, it sacrifices efficiency in replication to gradually overcome those defenses. This causes it to take more time for the infection to cause AIDS. Professor Philip Goulder said, "It is quite striking. You can see the ability to replicate is 10% lower in Botswana than South Africa and that's quite exciting. We are observing evolution happening in front of us and it is surprising how quickly the process is happening. The virus is slowing down in its ability to cause disease and that will help contribute to elimination." Goulder added that the average time from infection to the onset of AIDS has increased by 25% over the past 10 years.
It seems on it's way to becoming a more permanent and established disease.
From TFA: "Some virologists suggest the virus may eventually become "almost harmless" as it continues to evolve." Yes, I realize the the article says "Some" and "almost" but still I'd rather it be like dealing with a common cold than a full shutdown of my immune system.

Comcast is really excited. If HIV can get some positive press, they may have some hope, too.
I hate to say this, but if the virus is changing in that direction, it means it is more effective at infecting people that way. That's the way evolution works.
I guess if the virus is low key for a long time, it is detected later and retrovirals are started later, so it gets more chances to infect someone. Also, if the virus damages the body less, or the damage is slowwer, there are more chances it is not treated, so again it gets more chances to infect.
While it is good news that VIH is becoming less deadly, I wouldn't like it to become a chronic infection slowly debilitating and eventually killing its hosts. That would cause it not to be treated at all in poor countries.
When his defense asked, "Which computer has Jon Johansen trespassed upon?" the answer was: "His own."
"The virus is slowing down in its ability to cause disease and that will help contribute to elimination."
Not sure if this is incorrectly phrased or i'm incorrect in my understanding of viral evolution... The virus has evolved to slow down the process of causing disease, surely this is because it is advantageous to the continuation of this virus, if the host dies too quickly they are less likely to pass on the virus. So how does this contribute to eliminating the virus? is it not the opposite? Longer infected lifespan == Greater chance of transmission.
Perhaps he's not as pissed at us for the rampant Gay as the far right wing bible banging charlatans would have us believe!
On a more serious note, this is weird right? Isn't this the exact opposite of expected virus behavior? To evolve to become LESS likely to spread?
"If you love someone, set them free. If they come home, set them on fire." - George Carlin
One of the most nasty things a disease can do is to slowly replicate without causing symptoms. These long incubation periods are why Ebola, Tuberculosis, and Rabies are so dangerous. It makes them hard to detect and gives the host time to travel and potentially infect others without either party knowing. By the time the symptoms manifest it is often too late. By contrast, a disease that produces symptoms immediately is easily detectable and the host seeks treatment. If it is really really fast, they die before they can pass it on, and such diseases quickly eradicate themselves.
I don't look forward to a world where AIDS only manifests after 30 years, but everyone has it.
Slashdot digging up Drudge headlines a few hours later than I read them.... You guys are slipping hard. Just another roll of the DICE
Just went on a family vacation where my little brothers were playing a game on their iDevices.
The game - not giving it any specific advertisement - revolves around you "building" a disease meant to kill everyone on Earth. It gives you 3 categories on how the disease is perceived; Infectivity, Severity, and Lethality.
As Severity increases, the world becomes aware of the disease, the higher the severity the greater the focus the world has on finding a cure. So to combat this, you "devolve" traits that increase severity until the world doesn't care anymore or cares less than you want it to so infection continues.
Keeping on this fine line of severity until everyone in the world is infected, and then you "evolve" traits that kills everyone within minutes, winning you the game.
It seems HIV is taking a page out this games strategy book and sayin "Hey! Don't look at me, I won't kill you for another 20 years! Look at that guy over there first! (heuheuheuheu)".
Strange but true, at the end of the day all parasites are better off when they become symbiotic. There is no advantage to killing off your free meal, in fact your are better off lending a hand.
So far more than half the comments are as fucking stupid as this. I don't know why I even bother reading here anymore.
Shh! Don't get this kind of information beyond the sphere of well informed people. Some people may think that risky sex behavior becoming less dangerous is a thing.
Linux is for people who don't mind RTFM.
You're probably like a lot of readers, who now only read Slashdot for the cultural reference replies, the snarky replies or to find comfort in reading other comments with the same views as your owns.
And let's not forget the trolls and the pointless personal attacks, you stupid brain-dead half-wit redneck moron bastard.

I'm somewhat skeptical here. From my very small n=2 study, my husband and myself, infected the same year in 2006 (we both had HIV negative and positive tests that same year) with the same virus, as evidenced by genotype mutations test, I can tell you that my husband progressed from HIV to AIDS in less than a year, and had to go on antiretrovirals right away, whereas I didn't need medication for years and chose to remain without them for 4 years. I was in HIV controller studies. There was no change to my immune system on paper. But I was very tired, and I later chose to go on meds anyway. I had to drop out of the studies for this reason. I don't know what came of them. We are of different ethnicity - I am of caucasian and middle eastern descent; while my husband is asian; so our genetic are probably quite different.
It seems to me that this difference in disease progression between countries may have less to do with the virus itself evolving than it does with people's immune systems and genome evolving and becoming better able to deal with the virus.

The virus is slowing down in its ability to cause disease and that will help contribute to elimination.
Wouldn't being asymptomatic but contagious increase the spread of a virus rather than eliminate it?
Sarcasm mixed with parody and irony is one of the better recipes for moderation horror.
Doesn't this suggest things fall apart?
If so, is the court system going to censor this due to the establishment clause?
Because I heard somewhere criticism of evolution is basically forcing someone into religion.
HIV was never harmful to begin with. I guess this is the way science is going to handle this scandal?
"Oh, HIV will magically mutate into something harmless! That's why the disease model is wrong! Not because it was a lie all along!"
This is just unbelievable - the same scammers who claimed that a harmless retrovirus was the cause of 20 plus diseases, and different diseases in gay men, women, Africans, non-Africans, etc. are now conveniently telling us that the 'deadly virus' is 'less deadly'...
LOL. If AIDS was caused by a sexually transmitted virus, then why aren't millions of heterosexual westerners dying every year from it, seeing as all REAL STDs are increasing every year, and have been for decades?
There is no such thing as an 'HIV test' (the test insert itself tells you that it doesn't test for the presence or absence of HIV), the 'Western Blot' test is a total and utter fraud, giving completely different results for the same samples, and the 'anti-HIV' drugs are deadly and kill people - who we are then told died from 'AIDS'.
But don't believe me, try researching it for yourself. For a change.
Some people have been commenting about the huge differences between time of AIDS-onset in different HIV-infected individuals. What makes your immune system better at controlling HIV is your MHC capacity for presenting the antigens. The viral antigens have mutated to i) avoid triggering an immune response so it won't be well degraded in the first place, that happens by avoiding inflammatory pathogen associated molecular patterns (gp120 bings to a crappy receptor called DC-SIGN); ii) not fit well in most people's MHC cleft's, meaning that even when the pathogen is properly degraded, if you don't have good affinity with the MHC cleft, you won't be able to mount a good response based on T lymphocytes. The item II is what usually impacts the viral fitness in clinical practice. People with the same promiscuous MHC clefts which can cause autoimmune diseases are the ones who are usually slow developers. Since they can mount a good cellular response from the start, they will easilly get rid of most copies of the virus. What will be left will usually be the ones who have had mutations so big that they will not only not fit in the MHC cleft but they also won't bind well with CD4 or the correceptors. I've taken an extreme case, but this will happen in people with standard MHC`s who mount a standard answer. Also, the interesting thing about elite developers is that they don't mount the standard cytotoxic response which is expected against viruses. The dominant answer will be based on a novel type of T CD8+ nicknamed non-cytotoxic (duh) lymphocyte. These will, instead of killing the infected CD4+ lymphocytes, secrete anti-viral factors which will stall the virus reproduction. Another interesting example which shows that many diseases which we have are less harmful than our immune response. In this case, killing the infected cells means killing the own cells which will keep your immune system working, so it's a terrible idea, since the virus evolves faster, changing the antigens very fast while our immune system takes too long to mount a specific response. you will eventually suffer from immune exhaustion and that's AIDS.

He was in a really dark place when he was orchestrating those events.
Then those damn hipster goths became a thing and he decided dark wasn't cool anymore so he wrote the New Testament to be all PLUR and shit until like Fallen Apostates came and like corrupted his message man!
Media and entertainment sector people may now rejoice. They can sin with impunity with lessening health consequences. That is, until the Füçkdeath virus or something worse comes about.
News of the featured article coincides this week with news that the gay community is agitating to repeal the ban on blood donation by MSM participants (men who have sex with men, aka, gay men). The workers in blood donation centers all wear protective gear - gloves, coats and plastic full-length face masks. But what about me, the donor? I don't get any protective gear whatsoever (except a band-aid at the end). During the process, the blood donation puncture (an open wound) is completely exposed. All that is required for me to be infected is for another donor to bleed on me. And just so you understand the risk, I see someone else's free-flowing blood during every visit. It is not uncommon for a person sitting/standing/walking near me to literally dribble blood uncontrolled onto the floor, anywhere either inside or outside the donation center. Some readers may be inclined to start screeching "Phobia!!!" But is that cool? Among other things, the blood I donate goes to treat people with immune deficiencies. I would not be surprised if immune deficiency patients are walking around with literally my blood in their veins. The gay community receives enormous taxpayer largesse in the form of HIV research and abatement from the wealthiest nations on Earth. Maybe they should just leave well enough alone. Or, perhaps we should just ask, how long will it be before some other virus evolves, and we are faced with a new generation of Ryan White?
And comments like the title are stupid. Most people do not use condoms. Serial "monogamous" people when entering a new relation start doing it without checking the others background. There are some that are more risky prone and do not use them even in one night stands or with their friends with benefits that have probably a couple of other special "friends". Hell, right there in Africa they do not care about condoms, and do not even have the money to buy them (spending half of their monthly salary in condoms? Good luck with that).

"Some virologists suggest the virus may eventually become "almost harmless" as it continues to evolve"
It would be harmless if the virus did not encode for a homologue of the human lipid peroxidase inhibitor glutathione peroxidase. See Keshen's disease (China).

What they say might be happening but what *also* would explain that (and they did not check, a simple serum selenium test would differentiate) is:
Bloomberg news 2013:
"... selenium for two years were able to delay their need for antiretroviral therapies by about half compared with those given a placebo, according to research published in the Journal of the American Medical Association. The study followed 878 HIV-infected adults from Botswana, a nation with one of the highest rates of infection of the AIDS virus."

(they need to read Fosters papers, B, C and E boost the immune system but it's Tryptophan, Glutamine and Cysteine that the virus encodes for and strips from the body)
