The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and over time acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.
HIV infects vital cells in the human immune system such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells. HIV infection leads to low levels of CD4+ T cells through a number of mechanisms, including pyroptosis of abortively infected T cells,apoptosis of uninfected bystander cells, direct viral killing of infected cells, and killing of infected CD4+ T cells by CD8 cytotoxic lymphocytes that recognize infected cells. When CD4+ T cell numbers decline below a critical level, cell-mediated immunity is lost, and the body becomes progressively more susceptible to opportunistic infections.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

What are HIV & AIDS? HIV, or human immunodeficiency virus, is a type of virus that infects human immune cells. Over time, immune cells are lost, which weakens the immune system and allows patients to be infected by other viruses and develop several types of tumors. Subscribe - https://goo.gl/w5aaaV.

When you get infected with the HIV virus, you can get AIDS, which stands for 'acquired immune deficiency syndrome'. This means that you have a deficient immune system. This animation explains how you can get infected with the HIV virus and what it means when you are 'sero positive'. It also explains the different disease stages and possible treatment options. Healthchannel makes complex medical information easy to understand. With 2D and 3D animations checked by medical doctors, we give information on certain diseases: what is it, wat are the causes and how is it treated? Subscribe to our Youtube channel and learn more about your health!
The modes of transmission of HIV are numerous. This animation describes the common and less common ways in which HIV can be transmitted from one person to another. While HIV is most commonly spread from an infected person through vaginal or anal intercourse, as well as intravenous blood exposure through the sharing of needles, there are practices and measures that you can take to help minimize the risk of becoming infected.

I'm a 45 year old single mother of 3 and on 2/15/16 I found out that I had HIV. This is my story about how I contracted it, how I survived AIDS and how I live my life today with HIV. I originally put this video out for my Facebook friends, I had no idea it would get this king of attention. Every day is a new adventure on this new journey of YouTube and my story. I'm excited to be alive, excited to take this ride and excited to take you all along with me. Be sure to SUBSCRIBE, I will be doing more videos as long as there is interest :) You can also follow (message) me on Facebook by clicking the link on my main page (it's on the right hand bottom corner of the ocean cover photo). Thanks!
