The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans. Over time, they cause acquired immunodeficiency syndrome (AIDS), a condition 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. In most cases, HIV is a se_ually transmitted infection and occurs by contact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids. Research has shown (for both same-sex and opposite-sex couples) that HIV is untransmittable through condomless sexual intercourse if the HIV-positive partner has a consistently undetectable viral load. Non-s_xual transmission can occur from an infected mother to her infant during pregnancy, during childbirth by exposure to her blood or vaginal fluid, and through 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,[13] 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, leading to the development of AIDS.
HIV is a member of the genus Lentivirus, part of the family Retroviridae. Lentiviruses have many morphologies and biological properties in common. Many species are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with a long incubation period. Lentiviruses are transmitted as single-stranded, positive-sense, enveloped RNA viruses. Upon entry into the target cell, the viral RNA genome is converted (reverse transcribed) into double-stranded DNA by a virally encoded enzyme, reverse transcriptase, that is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase, and host co-factors. Once integrated, the virus may become latent, allowing the virus and its host cell to avoid detection by the immune system, for an indeterminate amount of time. The HIV virus can remain dormant in the human body for up to ten years after primary infection; during this period the virus does not cause symptoms. Alternatively, the integrated viral DNA may be transcribed, producing new RNA genomes and viral proteins, using host cell resources, that are packaged and released from the cell as new virus particles that will begin the replication cycle anew.

Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was initially discovered and termed both lymphadenopathy associated virus (LAV) and human T-lymphotropic virus 3 (HTLV-III). HIV-1 is more virulent and more infective than HIV-2, and is the cause of the majority of HIV infections globally. The lower infectivity of HIV-2, compared to HIV-1, implies that fewer of those exposed to HIV-2 will be infected per exposure. Due to its relatively poor capacity for transmission, HIV-2 is largely confined to West Africa.

  1. Sir எனக்கு ஒரு 7 மாதகாலமாக எண்ணுடைய ஆண் இன உறுப்பில் முன் தோல் பகுதியில் சிவப்பு நிற கொப்பளம் போல் வருகிறது. வரும் சிறிது நாள் இருக்கும் பிறகு அதுவாகவே போய்விடும் மீண்டும் வரும் அது என்ன காரணம்

  2. எனக்கு 57 வயது 5 வயது முதல் வாயில் புண் வரும் அதற்கு மருந்துகள் ஏதும் வேலை செய்யாது…. உடல் சூட்டை தணிக்கும் உணவுகளை எடுங்கள். 4 – 5 நாட்களை விட பலநாட்கள் நீடித்தால் கவனம் தேவை . வலி இல்லாத புண்களானால் அதிக கவனம் தேவை ஒரு சிலருக்கு புற்று நோய் ஆரம்ப கால நிலமையாக இருக்கலாம்…

  3. எனக்கு தெரிந்து எய்ட்ஸ் உள்ளவர்கள் பல வருடங்களாக பார்க்கிறேன் நன்றாக உள்ளனர் ஆனால் சர்க்கரை நோய் வந்தவர்கள் சில வருடங்களிலேயே இறந்து விடுகிறார்கள் ஆக எய்ட்ஸ் விட கொடுமையானது சர்க்கரை நோய் எனக்கும் சர்க்கரை நோய் உள்ளது

  4. Sir,
    Your video is good so that people can understand the symptoms of aids but no one is aware that maximum aids is caused through homo sex occasionally only through hetro sex
