  • 42. AVOID Sexual intercourse : HIV can infect the mucous membranes directly or when entered through cuts and sores during sexual intercourse. Unprotected Vaginal or Anal intercourse may result in receiving the virus. Oral sex : The risk of HIV transmission through the throat, gums or any other oral membranes has a lower risk then receiving it from the vaginal or anal area.Sharing injection needles: Injecting a needle and sharing it with another person can result to transmitting of the virus. Mother to Child: A woman who has HIV can pass the virus directly to her child before, or during birth, or through breast milk. Breast milk contains HIV, small amounts of breast milk doesn't effect adults, it can be transmitted to infants.
  • 43. Treatment For HIV There is no cure for HIV yet. Medical professionals are working on a cure for it, but there are some treatments. Drug therapy for patients who are devoted to taking all off their medication and have A CD4 count lower than 350 mL, which shows their immune system is subdued. Pregnant women and people who have kidney or neurological problem related to HIV, probably need treatment regardless of their CD4 Count. It's important to take all of their medication or the virus will quickly become resistant to the drugs.Antiretroviral drugs (ARVs)
