2.1 Counselling and voluntary testing
For women to take advantage of measures to reduce MTCT, they
will need to know and accept their HIV status. Voluntary counselling and testing
services therefore need to be widely available and acceptable. Ideally, everyone
should have access to such services since there are clear advantages to knowing
ones serological status.
People who know they are HIV-infected are likely to be motivated
to look after their health, perhaps with behaviour and lifestyle changes, and to
seek early medical attention for problems. They can make informed decisions
about sexual practices, childbearing, and infant feeding, and take steps to
protect partners who may still be uninfected. Those whose test results are
negative can be counselled about how to protect themselves and their children
from infection.
Furthermore, voluntary counselling and testing has an important
role to play in challenging denial of the epidemic: it helps societies which are
currently only aware of people who are ill with AIDS to recognize that there are
many more people living with HIV and who show no outward signs. However, it must
be emphasized that, unless people have real choices for action once they have
their test results, there is no good reason to take a test.
However, providing voluntary counselling and testing for the
whole population will not necessarily be justified in low HIV prevalence areas
where resources are scarce. And even where justified on the basis of prevalence,
it will not be a realistic option in some places because the health
infrastructure is not sufficiently strong to support the service. For, besides
the cost and practical requirements of providing counselling and testing itself,
there must be an efficient referral system to a range of other basic services
that people need once they have received their test results. These include
family planning, prevention and treatment of sexually transmitted diseases
(STDs), mother-and-child health services, and health care for infected people
including prevention and treatment of opportunistic infections, counselling, and
psychological support.
Taking local conditions into account, therefore, policy-makers
need to decide what kind of counselling and testing services are most
appropriate and feasible, and what action, if any, is required to strengthen the
health system that supports them. In particular, decisions need to be made about
whether to make counselling and testing available to the whole population
(comprehensive VCT); or to target the service at women or couples making use of
reproductive health services in areas where the HIV prevalence is especially
high (targeted antenatal VCT); or to offer counselling and testing to all women
attending antenatal services as part of a programme to reduce MTCT of HIV
(routine antenatal
VCT).
