Aggressive New HIV Virus Strain
Original Thread: medicaldaily.com
A new study has now identified a more aggressive strain of the HIV virus. The strain, called CRF19, has been spotted in parts of Africa, but it’s been found to be more widespread throughout Cuba. Researchers from the Rega Institute for Medical Research in Belgium found the strain is capable of turning from an infection to full-blown AIDS within three years, a lot faster than the average conversion time period of about 10 years. “We have a collaborative project with Cuba and the Cuban clinicians had noticed that they recently had more and more patients who were progressing much faster to AIDS than they were used to [seeing],” said Professor Anne-Mieke Vandamme, a professor in the Department of Microbiology and Immunology at Rega, according to Voice of America. “In this case, most patients had AIDS even at diagnosis.” The findings are especially concerning considering many people might not even know they have HIV infection. Firstly, because HIV tests normally can’t detect the virus during the first few weeks of infection (sometimes months), thus producing false negatives. Also, once a person gets through the flu-like symptoms that characterize acute infection — usually occurring about two to four weeks after infection — the virus undergoes a latency period, during which time it replicates and lives inside the body without causing any symptoms. This is the period that normally lasts 10 years before AIDS develops. Many of the current study’s patients, however, had gotten negative test results a maximum of one to two years prior to participating. Vandamme and her colleagues conducted their study by analyzing blood samples from 52 patients who experienced a rapid progression of AIDS and 22 healthy patients. They found CRF19 is a combination of the HIV subtypes A, D, and G, and suggested that this combination has allowed it to drive a high viral load, which in turn boosts an immune response and quickens the onset of AIDS. “There are two types of co-receptors (where the virus hooks onto human cells) that HIV can use: CCR5 or CXCR4,” Vandamme said. “In the normal progression of the HIV to AIDS, it often happens that the virus switches co-receptor. It almost always starts with using CCR5 and then it switches to CXCR4 after many years. And once it switches the progression to AIDS goes very fast.” While the findings are certainly a cause for concern, we’re no longer blindsided by the dangerous virus. ART is capable of managing the virus before it becomes AIDS if a sick person takes the right steps toward diagnosis. The only way to do this, however, is to avoid risky sexual behaviors, such as having unprotected sex or sex with multiple partners.

There is also a sub-type E in Thailand that progresses to AIDS in about 6 years.

However, it is not true that these new forms cannot be detected by current tests. As far as we know, our tests still can detect these infections. Honestly, if a person is infected with HIV, it makes precious little difference to him/her what strain it is. It is still a lifelong infection and it still can be controlled with the current meds we have. More aggressive forms are actually BETTER for public health. Because people progress to symptomatic AIDS quicker, it also means there is less time for them to pass HIV to someone else. Imagine if HIV kills a person within 1 day. The epidemic would be hardly as bad. Morbid but true.

Virus A when it infects a person he falls ill immediately and dies the next day. First of all, he only has 1 day to spread the virus to others. Secondly, all the public health authority needs to do is to quarantine every sick person for 1 day. Those that are not dead by the next day, you let them go. The epidemic will be gone and the problem solved. These kind of epidemics usually burn themselves out quickly because they kill the host too fast. Examples are Spanish Flu, Black Plague, Ebola. Virus B lies quiet in a person for 10 years. Nobody knows if he is infected or not. Yet he has 10 years to spread the virus to others. So as a health authority, what are you going to do? Make lots of TV ads to tell people who feel completely healthy to get tested? Most people would think "that cannot be me" and not get tested. So the epidemic continues and continues and continues. So don't you think having a more aggressive strain is good for public health? Bad for the individual who has it but good for public health.

Re: Aggressive New HIV Virus Strain
more aggressive, die faster, then wont spread as it will be isolated with care. Die slower, more chance to spread due to maybe some horny guy continue fuck more then spread more, then maybe 1 year later around 100 girls he fucked, fucked another 50 each. So imagine the distribution if the virus matured 1 year later per person
