In the US there is a compulsory prenatal screening of pregnant women for HIV infection by determining serum antibody.Such testing is provided for national guidelines, once performed in the first trimester or the first time a pregnant woman if it occurs later.It is part of a program for the prevention of perinatal transmission, according to online resource medlinks.ru.
To date it is not known whether there is enough of such testing as part of prevention of perinatal transmission of HIV from mother to child.The fact that the possible omission of the recent cases, the diagnosis of infection or infestation that occurred during pregnancy.
In order to determine the prevalence of acute HIV infection in pregnant group of researchers from North Carolina State University (USA) conducted a large study in which experts used data from the program STAT (Screening and Tracing Active Transmission).This program began in North Carolina back in 2002. In its framework in all government offices HIV testing all of the sampl
If in the course of the program revealed the presence of patients with acute HIV, he is in a very short time it was informed about the results, which are then confirmed by the analysis.Then, the patient was given counseling and, if necessary, on his way to a specialized surveillance.
In order to prevent vertical transmission of HIV-infected pregnant women were prescribed antiretroviral therapy immediately.Careful observation of the women were exposed before birth, and newborns.This study captured data, which were collected during the period from November 2002 to April 2005
results, which were obtained by researchers in the course of its work, suggest that quite a large proportion of cases of perinatal infection of the fetus (in this case - 50%) were developed in the mother during pregnancy is already in acute HIV infection.Experts believe that the algorithms that include testing for HIV RNA, in addition to the rapid re-testing of pregnant women for HIV antibodies in the second trimester of pregnancy can reduce the possibility of such an infection to a minimum.
