Correspondence to Kelsey K Case e-mail: Bulletin of the World Health Organization ; Planning HIV prevention programmes requires up-to-date information on the likely sources of new infections and mathematical modelling provides a framework for understanding epidemic patterns and for highlighting priority areas for prevention.
You can get or transmit HIV only through specific activities. Most commonly, people get or transmit HIV through sexual behaviors and needle or syringe use.
Only certain body fluids—blood, semen cumpre-seminal fluid pre-cumrectal fluids, vaginal fluids, and breast milk—from a person who has HIV can transmit HIV.
These fluids must come in contact with a mucous membrane or damaged tissue or be directly injected into the bloodstream from a needle or syringe for transmission to occur. Mucous membranes are found inside the rectum, vagina, penis, and mouth. For the HIV-negative partner, receptive anal sex bottoming is the highest-risk sexual behavior, but you can also get HIV from insertive anal sex topping.
Sharing needles or syringes, rinse water, or other equipment works used to prepare drugs for injection with someone who has HIV.
HIV can live in a used needle up to 42 days depending on temperature and other factors. Less commonly, HIV may be spread From mother to child during pregnancy, birth, or breastfeeding. Although the risk can be high if a mother is living with HIV and not taking medicine, recommendations to test all pregnant women for HIV and start HIV treatment immediately have lowered the number of babies who are born with HIV.
By being stuck with an HIV-contaminated needle or other sharp object. This is a risk mainly for health care workers. In extremely rare cases, HIV has been transmitted by Oral sex—putting the mouth on the penis fellatiovagina cunnilingusor anus rimming.
This was more common in the early years of HIV, but now the risk is extremely small because of rigorous testing of the US blood supply and donated organs and tissues. Eating food that has been pre-chewed by a person with HIV. The only known cases are among infants. Being bitten by a person with HIV.
Each of the very small number of documented cases has involved severe trauma with extensive tissue damage and the presence of blood. There is no risk of transmission if the skin is not broken. Contact between broken skin, wounds, or mucous membranes and HIV-infected blood or blood-contaminated body fluids.
Deep, open-mouth kissing if both partners have sores or bleeding gums and blood from the HIV-positive partner gets into the bloodstream of the HIV-negative partner. HIV is not spread through saliva.
How well does HIV survive outside the body? HIV does not survive long outside the human body such as on surfacesand it cannot reproduce outside a human host. It is not spread by Mosquitoes, ticks, or other insects.
Saliva, tears, or sweat that is not mixed with the blood of an HIV-positive person. Can I get HIV from anal sex? In fact, anal sex is the riskiest type of sex for getting or transmitting HIV. HIV can be found in certain body fluids—blood, semen cumpre-seminal fluid pre-cumor rectal fluids—of a person who has HIV.
Can I get HIV from vaginal sex? Most women who get HIV get it from vaginal sex.For health care workers on the job, the main risk of HIV transmission is from being stuck with an HIV-contaminated needle or other sharp object.
However, even this risk is small.
Scientists estimate that the risk of HIV infection from being stuck with a needle used on an HIV-infected person is less than 1%. San Francisco AIDS Foundation is a California nonprofit public benefit corporation which has been granted tax exempt status under Internal Revenue Code section (c)(3).

Various modes of transmission of HIV are - Sexual. Most of HIV infections are by unprotected sexual relationship. Transmission occurs when infected secretions of one person come into contact with the genital, oral, or rectal mucous membranes of other person.
The use of latex condoms reduces the risk of sexual transmission of HIV by more than 85%.

Human immunodeficiency virus infection and acquired immune deficiency syndrome People with AIDS have an increased risk of developing various viral-induced cancers, including Kaposi's sarcoma, The most frequent mode of transmission of HIV is through sexual contact with an infected person.
