Why is there an increase in teenage pregnancy HIV/aids despite the introduction of sex education?

Sadly it's because it's in part low self-esteem at that age and feeling peer pressure. Also, most of the time young people (older as well) don't listen to what they don't want to hear or more--to what they think can't possibly happen to them.

Because in the heat of the moment it seem's people ignore and take the chance just to get a nut.

Is there an increase? Do you have statistics to back that up? It's hard to answer a question when the question assumes a statement is true without providing the background info.

i believe that ppl tend to get into sex which they will not mind if the otehr party refuse to use condom when they fail to overcome their desire, emptiness, lonliness.it is important for us to always have a clear mind, coz once u done it- there is no turning back...

Maybe more reports are being made known rather than the number of pregnancies. Did you know that the abortion rate is DOWN among teens?
6 :
In my own personal experience, I can say that a good reason for this is that some people don't learn until they make the mistake for themselves. I was 15 when I got pregnant with my son, and although I have always considered myself to be intelligent and smart, I didn't think it could happen to me. So, I think many teenage pregnancies are caused by the same thinking, not because of lack of knowledge on the subject.

What are the roadblocks in creating a cure for cancer and HIV/AIDS

What are the roadblocks in creating a cure for cancer and HIV/AIDS?
What is preventing scientists from creating cures for arguably the two biggest diseases today??

in both cases, the disease is rarely the same in two people. In HIV, the virus mutates and changes, and develops resistance to our drugs very quickly. It's hard because the diseases are ever-changing and aren't consistent between patients.
2 :
The problem with the HIV virus is that it mutates so quickly. By the time a a vaccine is created the virus always mutates into a different strain. The medicine then becomes useless because you are only protected against an old strain. So you are still completely vulnerable against the new one. Cancer can already be cured by chemotherapy and radiotherapy. However it is difficult to stop cancer occuring in the first place. The problem with cancer is that it is not just a virus or a bacteria which infects your body. Therefore you can not be vacinated against it. Cancer cells occur when your own cells divide, a process called mitosis, but the DNA is miss-copied. This then leaves you with two cells that do not contain your own DNA. These two cells then divide and then they divide creating more and more cancer cells. so the only way you can stop cancer cells occuring would be by stopping your own cells dividing. But then you wouldnt be able to grow and you would die. The only hopes are treating it once you have it. These treatments however are becoming more and more accurate at fighting cancer cells and survival rates are always increasing. I am sorry if that is really hard to understand but it is hard to explain.
3 :
I don't know the exact scientific explanations but basically the diseases are constantly changing and mutating, so it is basically impossible to create ONE medication or one cure that would affect all of the different strains or viruses. They are essentially like very extreme versions of the common cold. There is no cure because there are millions of strains that are always changing. You can get medication to get rid of the symptoms though. I hope I helped! EDIT: This explanation only applies to HIV, I do not know much about cancer.

The virus replicates in the lining of the gut and does much of its damage to the immune system there, Satya Dandekar, chairwoman of the Department of Medical Microbiology and Immunology at the University of California Davis Health System, and colleagues reported. Writing in the Journal of Virology, Dandekar said the study was the first to explain why the drug cocktails taken by HIV patients so often fail to work completely. "The real battle between the virus and exposed individuals is happening in the gut immediately after viral infection," she said in a statement. "We need to be focusing our efforts on improving treatment of gut mucosa, where massive destruction of immune cells is occurring. Gut-associated lymphoid tissue accounts for 70 percent of the body's immune system. Restoring its function is crucial to ridding the body of the virus." HIV cannot be cured but the drugs, known as highly active antiretroviral therapy, or HAART, can keep the virus under control. At first, doctors had hoped that years of treatment might eventually eradicate the virus, but, 25 years into the epidemic of AIDS, it is clear that cannot happen. That is because the virus can hide out quietly in reservoirs, which include certain immune cells. The gut is clearly important, too, Dandekar's team said. "We found a substantial delay in the time that it takes to restore the gut mucosal immune system in those with chronic infections," Dandekar said. "In these patients the gut is acting as a viral reservoir that keeps us from ridding patients of the virus." The mucosa are the wet tissues that line the nose and throat, the genitals and the inside of the gut. HIV often infects people via the mucosa. Dandekar's team has been studying HIV-infected patients who, even without treatment, have survived more than 10 years with healthy immune systems, including the T-cells that are attacked by the virus. "We looked at their gut lymphoid tissue and did not see loss of T-cells there. This correlated with better clinical outcomes," Dandekar said. So they started the current study, following 10 patients being treated with HAART, taking blood and gut samples before and after three years of treatment. They found evidence of inflammation, which disrupts tissue function, promotes cell death and upsets the normal balance of gut bacteria. Dandekar said these findings suggest anti-inflammatory drugs may help HAART work better.
