Human Immunodeficiency Virus
(HIV)What is human immunodeficiency virus
(HIV)?Human immunodeficiency virus (HIV) causes acquired immune
deficiency syndrome (AIDS), which kills or impairs cells of the immune
system and progressively destroys the body's ability to fight infections
and certain cancers. The term AIDS applies to the most advanced stages of
an HIV infection.
How is HIV spread?HIV is spread most commonly by sexual contact with an infected
partner. HIV may also be spread through contact with infected blood,
especially by sharing needles, syringes, or drug use equipment with
someone who is infected with the virus. Most babies with HIV contract the
infection from their HIV-infected mother during pregnancy. According to
the Centers for Disease Control and Prevention (CDC), HIV transmission
from mother to child during pregnancy, labor, and delivery, or by
breastfeeding, has accounted for 91 percent of all AIDS cases reported
among US children.
What are the symptoms of HIV?The HIV virus may cause flu-like illness within a month or two
after exposure, although there may not be any symptoms at all. Persistent
or severe symptoms may surface within two years in babies born with an HIV
infection.
The symptoms of HIV may resemble other conditions or medical problems.
Always consult your baby's physician for a diagnosis.
The National Institutes of Medicine, the American College of
Obstetricians and Gynecologists, and the American Academy of Pediatrics
and other health organizations recommend HIV testing of all pregnant
women. Prenatal care that includes HIV counseling, testing, and treatment
for infected mothers and their children saves lives and resources. Current
recommendations are for HIV-positive women to take specific medications
during pregnancy and during labor. Blood tests are also performed to check
the amount of virus. Newborn babies of HIV-positive mothers also receive
medication for the first 6 weeks of life. Studies have found this
treatment can reduce the chance of a mother's transmission of HIV to her
baby from 25 percent to 8 percent.
Cesarean delivery may be recommended for HIV-positive women. This can
help reduce the transmission of the virus to the baby. Because breast milk
contains the virus, HIV positive women should not breastfeed their babies.
