In the period of 1999-2003, a double blind trial was performed with 140 patients selected randomly divided into 4 groups, authors predicted TCD4+ count of HIV infected persons from the results of skin test using dinitrochlorofenyne (DNCB). The slope of the regression line was greater significantly than zero, indicated that TCD4+ count decreases as the skin reaction to DNCB decreases (slope = 11.37, 95%Cl = 9.82 to 12.91, p=0.005, Y = 166.06 + 11.37X, r2 = 0.61).

Molecular epidemiological study of the HIV infection in Vietnam showed that recombinated HIV-1 subtype CRF01 (E subtype according to old classification) is still largely predominant either among injection drug users or persons infected though sexual intercourse. However, the presence of other HIV-1 subtypes B, C and other recombinated viruses indicated that HIV infection in Vietnam might become more complex with entry of different generic HIV-1 subtypes and other recombinated viruses

The initial study of natural protection against HIV-1 infection among exposed uninfected intravenous drug users in Vietnam showed that this people had more immune system with activation than normal people. The peripheral blood monocysts in some people resist disease-induced viruses in vitro by two mechanisms: target cells (T CD4) resist or less sensitivity with HIV-1 virus or inhibit viruses from T CD8 cells

Studies of HIV/AIDS in 1992-2004 show that HIV/AIDS endemic has been recorded since 1992. During 1999 - 2004, it has developed very fast. There were 1,618 accumulated HIV cases, 253 AIDS, and 186 deaths of AIDS. 100% of districts and towns with 81.3% of communes have people infected with HIV. The HIV cases in Nam Dinh town reached up to 59% of total number of the whole province. The HIV prevalence of the province is 81.6/ 100.000 people. Infection rate in Nam Dinh town is 409/100.000 people, 5.5 - 17 times higher than that in other districts. The trend of HIV infection rate among risk groups increased by 27,7% in drug abuser group and 5% in prostitute group. There is the need to inhance the prevention activities, media promotion, addressing social issues to curb the spread.

The study was to assess the epidemiological characteristics of HIV/AIDS in Nam Dinh 1992-2003. HIV/AIDS endemic has been recorded since 1992. During 1999 - 2004, it has developed very fast. There were 1,276 accumulated HIV cases, 164 AIDS, and 107 deaths of AIDS. 100% of districts and towns or 77% of communes had people infected with HIV. The prevalence of HIV infection is 64/100,000 residents in Nam Dinh town, reached up to 62.3 % of total number of the whole province. The prevalence in injecting drug users is 27.% (2003), in pregnant women and recruits is 0.38% and 0.97%, respectively. The prevalence of HIV infection is increasing both in the vunerable groups and in communities.

An inquiry was conducted in HIV/AIDS cases and AIDS deaths in 21 sentinel provinces in the period of 1999-2001. In An Giang, Kien Giang provinces, sex female workers underwent interview, intervention, blood examination,… Results showed an increasing tendence of HIV with complex evolution in morphology, in infective objects, in age. There were considerable defferences between various region. The incidence in male was 85.73% and female 14.24%. Among male HIV infected, the incidence in North was higher than in South regions. 61.9% of infections were drug users and the incidence was difference between various locations. There was a tendence of raising of sexual transmitted infection and the prostitutes were rather high risk transmitted people with their low knowlegde on HIV/AIDS, on STD, the prevention ways, low rate of condom use. After intervention there was an enhance of their user of these measures

A study on 784 HIV positive cases detected between 1996 and May 2004 in Thaibinh city and Kienxuong district showed that the HIV/AIDS prevelance in the studied areas was 205.56/100,000 people. The HIV positive cases were mainly in the 20-39 age group. In the households with one positive case accounted for 91.6%. The households with more than 1 positive case was 7.6%. The orphans (parents died from AIDS) were 0.8%. Among all HIV positive cases, 68.75% were drug users, 10.45% were STI people, 2.93% were commercial sex workers, and 1.9% were pregnant women

A pilot cross-sectional study was conducted in order to identify the need and the use of HIV/AIDS counselling services and real situation at the counselling facilities in Hanoi. data was obtained using a self- administered questionaire to 8 groups of people with risk behaviours related to HIV/AIDS. These groupd also took part in group discussions. Structured in-deep interviews with counsellors and observation at counselling facilities were also conducted. The need for using HIV/AIDS counselling services was low (45.7%). Only 41.6% of persons who have need for counselling had use service. People living with HIV/AIDS and their families were the two main groups using these services. The reason for low utilisation was user’s poor perception of HIV/AIDS infection risks. Problems from the providers also con tributed to the services: inappropriate organisation and investment. The main fidings suggest that increase of the risk perception of HIV/AIDS of individual and community serveices, it should be reorganised. At the same time, the counselling activities should be socialised, and considered as the key task of the whole society and community, not only that of the health sector.

Background: With the development of HIV/AIDS pandemic in community, amount of HIV/AIDS people more and more increase in prison. Objectives: Determine the rate of HIV/AIDS infection of prisoners at Binh Dien prison. Learning about related elements to HIV/AIDS infection. Subjects and method: Prisoners at Binh Dien prison. Method: 492 prisoners were chosen, interviewed directly and taken blood samples to HIV test. Using cross-sectional study on accidental samples. Techniques were used in this study: SERODIA-HIV and ELISA technique. Results: The rate of current HIV/AIDS infections was 21,74%, some HIV/AIDS related factors in the prison included sex, religion, income source, marrital status, common knowledge of HIV/AIDS, drug addiction history, needle sharing, sexually transmitted disease history, body tatoos and forskin inserted with metal balls, alcohol and beer drinking history, some factors such as: age and educational level were not associated with HIV/AIDS infection in prison. Conclusion: Strengthen interventional activities in prison to prevent HIV/AIDS spread between prisoners. To prisoners who were not infected HIV/AIDS: strengthen educational communication to they may prevent themselves from HIV/AIDS infection behaviors. To HIV/AIDS prisoners: Need to educate and consult especially to they have right behaviors, prevent HIV/AIDS spread for the others while they were in prison as well as they return to society.
