Abstract
This research was conducted from October 2005 to September 2007 with the aim of
developing a counseling system and determining the efficiency of HIV counseling in preventing the
maternal transmission of HIV at the antenatal care unit in Pong District, Phayao Province. The first
step was undertaken in 2004, namely a situation analysis and result evaluation for planning. The
second step in 2005 developed the couple HIV counseling system, promoted project and personnel
preparation, and tried a one-stop health center approach. The third step in 2006 implemented
the system, while the fourth step in 2007 adjusted and further developed it. The device for
collecting data was evaluated, i.e. an awareness form for HIV counseling and gathering general data
for that purpose in the antenatal care unit. Analysis was by mean, percentage and standard
deviation. The result of the study showed that after counseling the mean awareness of the couples
was higher than before counseling and that success had been achieved in developing the couple
HIV counseling system in the health center of Pong District. Coverage was more 100 percent of
health centers and more than 80 percent of all such couples in 2007 in the antenatal unit; now all
health centers have a couple HIV counseling system. There was no instance of one mate infecting
another and in more than 80 percent of the pregnancies of an HIV-infected mother there was no
transmission of the virus to the child.
