HIV Causes and Risk Factors

Risk factors
The highest risk factors for contracting HIV include:

  • Having unprotected sex with someone who is HIV-infected
  • Using needles/syringes used by someone who is HIV-infected
  • Receiving blood or transplanted organs from someone who is HIV-infected (there is little risk now, since regular testing began in 1985)
  • Passing HIV-infection from mothers to children through breastfeeding, pregnancy, or birth.
