Precautions of HIV/Aids to enter human body

HIV is transmitted when the virus enters the body, usually by injection of infected cells or sperm. There are several possible ways in which the virus can enter.

•  
  • In most cases, HIV infection is spread through sex with an infected partner. The virus can enter the body through the lining of the vagina, vulva, penis, rectum or mouth during sex. Although the relationship is the main risk factor, the transmission of oral sex is also possible.
  • HIV frequently is spread among injection drug users who share needles or syringes that are contaminated with blood from an infected person.
  • Women can transmit HIV to their babies during pregnancy or birth, when infected cells enter the maternal

  • HIV can spread in health care facilities through accidental needle stick or contact with contaminated fluids.
  • Very rarely, HIV is spread through transfusion of contaminated blood or blood components. All blood products are tested to minimize this risk. If tissues or organs from an infected person are transplanted, the recipient can get HIV. Donors are now tested for HIV in order to minimize this risk.
  • HIV was spread when an infected person’s organs are transplanted into a recipient who is not infected. Because donors are routinely tested for HIV in the United States, it does not usually occur. However, a recent incident in Taiwan when the HIV test results for the donor were mistakenly thought it was negative.
  • People who already have a sexually transmitted infections such as syphilis, genital herpes, chlamydia, human papillomavirus (HPV), gonorrhea, or bacterial vaginosis are more likely to contract HIV during sex with an infected partner.

• The virus is not spread by casual contact such as food preparation, sharing towels and bedding, or via swimming pools, telephones or toilet seats. The virus is also unlikely to spread through contact with saliva, if it is not contaminated by blood.
