HIV/AIDS has become much more than a health issue. HIV/AIDS is a development issue, it's a security issue.
From the beginning, the HIV/AIDS pandemic has presented very difficult challenges.
There's so much stigma around HIV/AIDS. It's a challenging issue, and the people that already have been tested and know their status find it very, very hard to disclose their status, to live with that virus, and to even seek out the kind of information they need. This experience of going to South Africa a decade ago really woke me up to the scale of the HIV/AIDS pandemic in sub-Saharan Africa, how it was affecting women and their children. I haven't been able to walk away from it.
The United States has put more money on HIV, AIDS, malaria and tuberculosis than any country in the world and it's having an impact real quick.
I hope to continue to be an activist for kids and teenagers and especially girls who are living with HIV/AIDS, because all over the world, people don't have the same rights that we do in the United States.
In terms of medicine, I've generally been pretty interested in public health issues as they relate to sub-Saharan Africa on a broad scale - HIV/AIDS, malaria etc.
That makes climate change a bigger public health problem than AIDS, than malaria, than pandemic flu.
HIV AIDS is a disease with stigma. And we have learned with experience, not just with HIV AIDS but with other diseases, countries for many reasons are sometimes hesitant to admit they have a problem.
The fight against HIV/AIDS requires leadership from all parts of government - and it needs to go right to the top. AIDS is far more than a health crisis. It is a threat to development itself.
Just to be clear, if, like Pat Robertson, you somehow missed all the evidence, all the research, the depth and breadth of all the knowledge garnered about HIV and AIDS over the past three decades, you cannot get HIV if you share towels.
To tell you the truth, I'm shocked, as I travel across this country, at how little people know or don't want to know about HIV/AIDS. There are a lot of people who don't know that HIV is one thing and AIDS is another. Those people just think it's one big old alphabet of a disease.
I am sure it is in the medical textbooks, there are many things that cause immune deficiency and you will find therefore in the South African HIV and AIDS programme, that it will say that part of what we have got to do is to make sure that our health infrastructure, our health system is able to deal adequately with all of the illnesses that are a consequence of AIDS.
As of 2013, according to the World Health Organization, 35 million people were estimated to be living with HIV or AIDS globally, and 39 million have died from the disease. The epidemic of denial won, and now everyone knows there is money in the making of drugs for AIDS.
HIV/AIDS is the greatest danger we have faced for many, many centuries. HIV/AIDS is worse than a war. It is like a world war. Millions of people are dying from it.
When we can get the incidence of HIV down enough to turn the trajectory of the pandemic, it will assume a momentum of its own in diminishing HIV.
Its not even probable, let alone scientifically proven, that HIV causes AIDS. If there is evidence that HIV causes AIDS, there should be scientific documents which either singly or collectively demonstrate that fact, at least with a high probability. There are no such documents.
