एचआईवी और एड्स

HIV is spread through:

• Sexual contact with an HIV-infected person, especially intercourse or anal sex
• Transfer of HIV from a mother to child during pregnancy, childbirth, or breastfeeding
• A prick from an HIV-contaminated needle
• A blood transfusion with HIV-infected blood (rare today, due to testing of all donated blood for HIV infection beginning in 1985)

Rarely, HIV can be spread through:

• Blood from an HIV-infected person getting into an open wound of another person
• Being bitten by someone infected with HIV
• Sharing personal hygiene items with an HIV-infected person (razors, toothbrushes, etc.)

जोखिम कारक

Factors that increase your chance of getting HIV include:

• कई यौन साथी होना
• Being a man who has sex with other men and engages in other high-risk behavior (having unprotected sex, using drugs during sex)
• Being a woman who has sex with other women and men and also engages in high-risk behavior
• Injecting illegal drugs, especially with used or dirty needles
• Having regular exposure to HIV-contaminated blood or other body fluids (a concern for healthcare workers and people who work in correctional facilities)
• Being born to an HIV-infected mother
• Receiving donor blood products, tissue, organs, or artificial insemination
• Being an immigrant from geographic locations with high numbers of AIDS patients
• Having a sexual relationship with a high-risk individual or a partner already infected with HIV

The risk factor for AIDS is having HIV.

लक्षण

HIV may not cause symptoms for a number of years.

Early symptoms may appear a month or two after becoming infected. They may last a couple of weeks. These include:

• Rapid weight loss
• सूखी खाँसी
• गला खराब होना
• Recurring fever
• रात का पसीना
• Extreme, unexplained fatigue
• Swollen lymph nodes in armpits, neck, or groin
• White spots on the tongue or in the mouth or throat
• सिरदर्द
• Discomfort from light
• खरोंच
• अवसाद
• Irritable mood
• Memory loss or other neurological disorder

After these initial symptoms pass, there may be no symptoms for months to years. Then, the following symptoms may occur over the course of 1-3 years:

• Swollen lymph glands all over the body
• Fungal infections of the mouth, fingernails, toes
• Repeated vaginal infections (yeast and Trichomonas)
• Development of lots of warts
• Exacerbations of prior conditions, such as eczema, psoriasis, herpes infection
• दाद
• रात का पसीना
• वजन घटना
• जीर्ण दस्त

It can be 10 years or more before HIV progresses to AIDS. This happens when T helper cell levels fall below certain levels and opportunistic infections arise. Examples of opportunistic infections and other complications of AIDS include:

• Thrush (an overgrowth of yeast)
• Pneumonia (particularly Pneumocystis jiroveci pneumonia)
• Invasive fungal infections (resulting in brain and/or lung infections)
• Toxoplasmosis infection
• यक्ष्मा
• Viral brain infection
• कपोसी सारकोमा
• लिंफोमा
• ग्रीवा कैंसर
• Eye disease due to cytomegalovirus infection
• Severe intestinal infections, especially due to shigella, salmonella, and campylobacter
• Severe weight loss (wasting syndrome)
• Severe skin rashes
• Reactions to medications
• Psychiatric problems, including depression and dementia

निदान

The doctor will ask about your symptoms, medical history, and risk factors. A physical exam will be done. Your doctor may order tests, such as:

• ELISA test—used to detect HIV infection
  • 95% will have a positive test within three months of infection
  • 99% will have a positive test within six months of infection
  • If an ELISA test is negative, but you think you may have HIV, test again in 1 to 3 months
• Western blot blood test—usually done to confirm the diagnosis if ELISA was positive

उपचार

Medicines can prevent, delay, or control the development of AIDS in many people infected with HIV.

रोकथाम

To prevent becoming infected with HIV:

• Abstain from sex.
• If you do have sex use a male latex condom. This includes any sexual act that results in the exchange of bodily fluids.
• Do not share needles for drug injection.
• Limit your number of sexual partners.
• Avoid sexual partners who are HIV-infected or injection drug users.
• Avoid receiving transfusion of unscreened blood products.
• If you are a healthcare worker or work in a correctional facility:
  • Wear appropriate gloves and facial masks during all procedures.
  • Carefully handle and properly dispose of needles.
  • Carefully follow universal precautions.
• If you live in a household with an HIV-infected person:
  • Wear appropriate gloves if handling HIV-infected bodily fluids.
  • Cover all cuts and sores, yours and the HIV-infected person’s, with bandages.
  • Do not share any personal hygiene items such as razors, toothbrushes, etc.
  • Carefully handle and properly dispose of needles used for medication.

Recent studies found that circumcised men were significantly less likely to develop HIV infection compared to uncircumcised men.

To prevent spreading HIV to others if you are HIV infected:

• Abstain from sex.
• If you do have sex, use a male latex condom. This includes any sexual act that results in the exchange of bodily fluids.
• If you are prescribed medicines, be sure that you are taking them.
• Inform former or potential sexual partners.
• Do not donate blood or organs.
• Ask your doctor about contraception.
• If you do wish to become pregnant, talk to your doctor. There are ways to lower your baby’s risk of being born infected with HIV.
• If you have a baby, do not breastfeed.
