Can u be born hiv positive?

Yes, if the mother is HIV+

Babies born to HIV positive mothers are tested for HIV
differently than adults. Adults are tested by looking for
antibodies to HIV in their blood. A baby keeps antibodies
from its mother, including antibodies to HIV, for many
months after birth. Therefore, an antibody test given
before the baby is 18 months old may be positive even if
the baby does NOT have HIV infection. For the first 18
months, babies are tested for HIV directly, and not by
looking for antibodies to HIV. When babies are more than
18 months old, they no longer have their mother's
antibodies and can be tested for HIV using the antibody
test.
Preliminary HIV tests for babies are usually performed
at three time points:
鈥?birth to 14 days
鈥?at 1 to 2 months of age
鈥?at 3 to 6 months of age
If babies test negative on two of these preliminary tests,
they should be given an HIV antibody test between 12-18
months. Babies who test negative for HIV antibodies at
this time are not HIV infected.
Babies are considered HIV positive if they test positive
on two of these preliminary HIV tests. Babies who test
positive for HIV antibodies will need to be retested at 15
to 18 months. At 18 months, babies should have an HIVantibody test to confirm HIV infection. A positive HIV
antibody test given after 18 months of age confirms HIV
infection in children.
