In order to study on epidemiological factors, clinical manifestation of AIDS patients in Vietnam, a retrospective study on 5247 AIDS patients in the whole country has been conducted from 1993-2001. The results of study showed that most of AIDS patients were male and young and almost cases used the injection. Clinical manifestations were prolonged fever and persistent diarrhea over 1 month and persistent diarrhea. Duration of HIV infected to AIDS and to death was short. It needs to implement voluntary counseling testing program and strengthen AIDS survey activities in Vietnam.

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.

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.

Various specialtus were developed with a large professional staff of qualified levels, prosperious experiences and long carrier in health service. However, in this system there are some bad facilities poorly equiped, with a low capacities both in quantities and in qualities.

A retrospective survey on HIV/AIDS control data from health services and related functional branches of Nghe An province in the period of 1997-2002 was conducted. The epidemy have evoluated continuously. In 1996, 4 HIV/AIDS infected persons immigrated from other province. In December 2002, 1922 had immigrated, among them 256 were transferred to AIDS patients and 83 died. There were 1510 native people were infected with HIV, among them 183 were transfered to AIDS and 72 died. About 90% officers and cadres, 80% urban population, 70% rural and mountain population have had awareness and proper attitude about HIV/AIDS. 70-80% high risk subjects were approaches the education and consultation of HIV/AIDS control

The number of pregnant women affected with HIV/AIDS in Hung Vuong hospital has increased rapidly. During 8 years (1996-2003), the rate increased from 0,05% to 0,81% (2002) and decreased to 0,7% in 2003. The percentage of HIV positive pregnant women below 19 years old has increased from 12,5% (1996-1998) to 16,8% (1996-2003). Primigravida with HIV(+) test have increased from 37,5% (1996-1998) to 60% (1996-2003). Number of HIV(+) pregnant women living in the suburb has increased from 23% (1996-1998) to 28,32% (2003), that means HIV has attacked women living in the countryside. Counselling is still be inadequate, as a result, 1,5% women who knew that they had HIV test(+) continued to have another pregnancy.

Acquired Immune Deficiency Syndrome (AIDS) has been one of the main public heath problems that the Chinese public is facing. In order to estimate and predict the development of the epidemic situation, we studied on cellular automaton with the mechanism and characteristics of AIDS, and sets up an AIDS model on the base of the principle of cellular automaton. By studying the model, we analyzed the segregation power and AIDS-immune persons' influence on the transmission of the diseases. Some estimations and predictions can be drawn by studying model parameters. The structure of the model is flexible, and so it can change control tactics during evolution. Traditional differential equation cannot come up to it under the circumstances. It serves as tool with a great significance to the control as well as the prevention of AIDS.
