HIV Transmission Captured On Video

Technology Review has promising news on the AIDS front: researchers have captured HIV T cell transmission on video. The upshot could be new avenues of treatment. "The resulting images and videos show that, once an infected cell adheres to a healthy cell, the HIV proteins... migrate within minutes to the contact site. At that point, large packets of virus are simultaneously released by the infected cell and internalized by the recipient cell. This efficient mode of transfer is a distinct pathway from the cell-free infection that has been the focus of most prior HIV studies, and reveals another mechanism by which the virus evades immune responses that can neutralize free virus particles within the body."

There is a way to beat the HIV virus

[Anonymous Coward]

I have an idea how to stop HIV and it involves the same technology found in terminator seeds.

In a nutshell, the government sanctions the agricultural giant Monsanto to engineer a new strain of HIV virus with a limited lifespan beyond a certain generation with ability to recode the DNA as it progresses. This virus could be hostile to all the known HIV strains out in the wild and force them out. People voluntarily get infected with this new virus as means of guarding against incurable HIV infections. Since this new virus can be regulated upon demand, Monsanto can then minimize the damage for a low monthly fee by supplying you with various off switches to reduce the infection. They could set up various plans depending on your budget. Silver and Gold plans would have limited side effects to encourage you to upgrade to the Platinum plan and get better viral sterilization methods.

I think this could work.

Ok I'll bite ... "HIV Transmission Captured On Video" ... I can't be the first to think, its probably been caught on videos before now!

It's been caught on video many times before - and sold.

Scary stuff, really.

> Roxx, on learning about James being HIV-positive, said, "It totally made me realize how I trusted this system that wasn't to be trusted at all, because it obviously doesn't work," and "I thought porn people were the cleanest people in the world."

"The system" in this case is inherently flawed.

After initial HIV infection, it can take up to six months for someone to start producing HIV antibodies (seroconvert). And unfortunately, most HIV tests don't check for viral load, but check for the presence of antibodies.

So basically, you have a window period of up to six months where you are contagious but will come up negative on tests.

Re:Is HIV dangerous? It's a "consensus" anyway...

HIV causing AIDS? It's a consensus that has an overwhelming amount of evidence to back it up. I won't even begin to try to summarize it all, but I will describe the gist of it.

Causality between a microorganism and disease is commonly established through the demonstration of Koch's Postulates. These are not hard-fast rules; some of Koch's Postulates are difficult to prove through ethical experiments. However, in the case of HIV, all of Koch's Postulates have been fulfilled:

1. The microorganism must be found in abundance in all organisms suffering from the disease. The virus has been isolated from every patient with AIDS. On top of that, people have sequenced its genome, elucidated its structure, and taken a picture of it.
2. The microorganism must be isolated from a diseased organism and grown in pure culture. The virus has been isolated from patients with AIDS, and grown in culture. Critics cite the fact that this is very difficult to do, and requires special conditions. Most scientists believe that such special conditions are necessary when you are trying to culture something like a retrovirus. Special requirements for growth are not unique to HIV; for example, no one has ever successfully cultured a pathogenic strain of Treponema pallidum (syphilis) in vitro, but anyone who has ever had syphilis will tell you it is a VERY real disease.
3. The cultured microorganism should cause disease when introduced into a healthy organism. When introduced into a healthy individual, the HIV virus has been found to cause disease. It should be noted that this has only happened a few times in monitored environments, through needle-stick exposures; however, it would not be ethical to experimentally inoculate a healthy person with HIV. There is an overwhelming body of non-experimental evidence to support bloodborne and sexual transmission of the HIV virus, and the evidence shows that everyone who contracts HIV eventually gets AIDS - with OR without therapy.
4. The microorganism must be reisolated from the inoculated, diseased experimental host and identified as being identical to the original specific causative agent. This has been demonstrated in the cases of needle-stick exposures.

Anti-retroviral therapy - while itself is quite dangerous and filled with side effects - has nevertheless been shown in numerous studies to reduce morbidity and mortality in HIV+ patients. Anti-retroviral therapy has also been compared to placebo, and its effects have been found to be beneficial over placebo. Other studies, mostly performed in Africa, have examined the "natural history" (i.e. the untreated progression) of HIV infection; such studies have shown that the natural history of HIV infection leads to the severe immunocompromise characteristic of the AIDS syndrome, followed by death.

Yes, there is plenty of money flowing into AIDS research and drugs. However, that fact fails to prove anything related to this discussion, one way or another. There was a point in time when the HIV-AIDS connection was, indeed, a hypothesis; many people cite evidence from that period of time in making the claim that HIV->AIDS is still a widely disputed theory. However, a careful examination of the current scientific evidence will reveal an overwhelming body of evidence supporting a causal relationship between HIV and AIDS.
