Background: From the first case of HIV/AIDS in Vietnam on December 1990, up to June 30th 2007, there were 126,543 cases of HIV infections, 24,788 AIDS patients and 13,874 AIDS-related deaths. Strong political commitments were given by the government to develop HIV/AIDS prevention and control programs. Objectives: To discover the current state of the HIV/AIDS epidemic and HIV/AIDS prevention as well as control in a number of northern provinces and to discover various related factors. Subjects and method: An analytic cross-sectional study was carried out from 2006 to 2007 on the leaders of local authorities, health facilities and HIV-infected people in 7 northern provinces. The documents and reports related to HIV/AIDS prevention and control were reviewed. Results: HIV/AIDS epidemic is not the problem of only the health system; it was increasing as a complex problem. HIV infection rate was higher in Quang Ninh, Ha Noi, and Son La. Among HIV-infected people, drug-injected users accounted for 93%. The prevention of HIV/AIDS has been planed, carried out in all communities, but is not very efficient and it requires high-quality solutions that should be widened to control and reduce this disease. Conclusion: The efficacy of current HIV/AIDS prevention and control program was not proficient.

Background: Success in preventing HIV transmission from mother to child has been confirmed, however intervention remains difficult in both services and access barriers due to discrimination and stigma. Objectives: To clarify the HIV prevalence in pregnant women and evaluate the indicators related to the impact of intervention on prevention of mother-to child transmission of HIV. Subjects and method: This study was carried out in 5 districts in 5 provinces that implemented the Prevention of Mother to Child Transmission (PMTCT) Project. The interventions included the training to provide knowledge, skills on counseling, testing and supervision on PMTCT. The data were collected from designed-questionaires. Results:The results showed there are 100% of pregnant women that came for antenatal visits, had voluntary test counseling. The prevalence of HIV (+) among pregnant women was 0,43%. There were 57 infants born to mothers with HIV (+); received prophylaxis treatment. At the time of the study, there were 31 infants at 18 months of age that received HIV test and all of them were confirmed as negative. Conclusion: Intervention on PMTCT was effectively achieved and should be expanded nationally. Communication, counseling is very important to encourage pregnant women with HIV (+); visit for antenatal care, followed up by health facility and strict adherence to the PMCT schedule to diminish the chance of transmission to their infants.

The role of natural killer cell in natural protection against HIV-1 infection was studies on 37 injected drug users (IDUs) who had been in high risk of exposure to HIV-1 but remain uninfected (EU) for many years follow-up. A comparison had been conducted between 10 IDUs who underwent seroconversion and 28 unexposed blood donors (controls). The results showed that the lytic activities and cytokines production of natural killer cells were significantly augmented in EU IDUs. This findings supports the role of natural killers cells in contribution to the natural immune response against HIV-1 infection among exposed uninfected IDUs
