The Acquired immune deficiency syndrome (AIDS) is brought about by the deadly retrovirus-the human immunodeficiency virus (HIV). In the USA alone an estimate of 120,000 - 160,000 women are HIV- infected and most are even unaware of it. In India women account for 38% of HIV cases.
In the year 2007 it was estimated that there were 2.1 million children worldwide who were infected by HIV and in almost 85-90% the infection occurred due to mother-to-child transmission.
HIV is mostly transmitted in the following ways:-
• Sexual intercourse with an infected partner
• Coming in contact with infected blood and other body fluids or blood products
• Using infected needles
• From an infected mother to her child during delivery or breast -feeding
It takes a minimum of 3 months for a person to develop antibodies to HIV. This phase is called the ‘window period’ and, any diagnostic test would show the correct result only after that window period.
If antibodies against HIV are detected during blood tests then that person is reported to be ‘HIV- positive’
. Although this status does not mean that the person has AIDS, a HIV –positive individual is capable of transmitting the virus to others.
People who are HIV – infected do not display the symptoms immediately. The period between HIV infection and developing full- blown AIDS may be anything between 3 months to 17 years.
HIV works by destroying the immune system of the infected individuals who then become prone to dangerous and life- threatening conditions such as lymph node tumors and pneumonia. But with improved drugs in the market, the prognosis for AIDS patients has vastly improved.
The bottom line is that pregnancy does not necessarily make the mother's HIV disease any worse, however the mother or the couple in such situations need to be counseled about her own health and health of the baby. Long term results of treatment, its possible side-effects and outcomes should also be discussed. HIV and Pregnancy Facts
• A baby born to a HIV-infected woman has a 25% chance of being HIV-positive, without treatment or interventions High -risk women
• HIV and the ensuing treatments increases the risk of premature birth
• A combination of anti-retroviral therapy and C- section greatly reduces the HIV transmission to the babies by less than 1 per cent
• If one of the partner is affected a couple may opt for artificial insemination
• Infertility clinics that accept sperm donors will generally ensue that the man who donates sperm submits his test report showing the HIV status. This is generally done twice- once during donation and then again after 3 months. Only if both the tests are negative the sperm are accepted for use.
Women become HIV-infected through the following ways-
• Unprotected heterosexual sex (vast majority)
• Women whose male partners use IV drugs
• Women whose male partners have male sex partners
• Women who use IV drugs
• Women with multiple sex partners
• Women who have sexually transmitted diseases
• Recipient of blood transfusions where the blood is infected Who needs HIV Screening?
Although it is recommended thatall adults who are between 13 and 64 years are screened for HIV, It is mandatory that all women be screened for HIV well before their conception. If that is not possible then the screening must be done during pregnancy. This is to ensure that appropriate treatment can be carried out to protect the baby.
Studies have revealed that drug treatment during pregnancy benefits women who are HIV- infected. It is therefore advisable for all women who are pregnant, with special emphasis on the high risk group, to be routinely checked for HIV’s presence and to repeat the screening during the third trimester. This will help to protect the babies of those infected from acquiring the infection.
