There is a potentially high risk of HIV spreading from people living with HIV/AIDS. We conducted a cross-sectional study to examine HIV risk behaviours and their determinants among people living with HIV/AIDS. Eighty-two percent had been sexually active. Sex with multiple partners was reported by 20% and consistent condom use by about one third. More than half of the participants (52%) reported having injected drugs during the previous month, and 35% of those had shared needles and syringes. Voluntary HIV testing and having received condoms or injection equipment from the local HIV prevention program, were found to be significantly associated with fewer HIV risk behaviours. Having learned recently about personal HIV status, multiple sex partners, low educational attainment and young age were found to be associated with higher HIV risk behaviours. Giving high priority to targeted preventive and support programmes is likely to be a highly cost-effective strategy.
The goal of this study was to describe the evolution of the HIV epidemic in Vietnam and its responses. Surveillance was conducted in 8 provinces in 1994, expanded to 12 in 1995, 20 in 1996, and 30 in 2001. Sentinel populations were sexually transmitted disease (STD) patients, female sex workers (FSWs), injection drug users (IDUs), tuberculosis (TB) patients, antenatal women, and military conscripts. Vietnam is in the concentrated epidemic stage. HIV prevalence had increased significantly in all surveillance population groups in the 1990s. HIV prevalence in the south is higher than in other regions of the country. The national HIV prevalence increased from 10.1% in 1996 to 32% in 2002 among IDUs, from 0.6% in 1994 to 6.6% in 2002 among FSWs, from 0.4% in 1994 to 2.4% in 2002 among STD patients, from 0.03% in 1994 to 0.34% in 2002 among pregnant women, from 0% in 1994 to 0.7% in 2002 among army military recruits, and from 0.5% in 1994 to 3.6% in 2002 among TB patients. The government has a strong commitment to control the epidemic and has implemented many activities for HIV prevention and control. Vietnam's HIV epidemic is predominantly among IDUs. Current intervention activities have not been sufficient to reduce HIV transmission. Vietnam needs to strengthen responses by scaling up the best practices in the most affected population groups by implementing internationally recognised effective interventions appropriately.
Abstract:This study aims at sustainably developing rural tourism in An Giang Province, an agricultural province located in the South of Vietnam, by identifying the determinants of the satisfaction and revisit intention of tourists based on both qualitative and quantitative approaches. From exploratory interviews with experts and comprehensive group discussions, we developed a questionnaire for an official survey of 507 tourists at different tour-sites in An Giang Province. It is found that: (1) there are seven key factors affecting the satisfaction of the tourists, including: spirituality, tourism safety and security, people, food and beverage, natural environment, service prices and tourism infrastructure; and (2) revisit intention of tourists is affected by six factors, including: satisfaction, spirituality, tourism safety and security, people, food and beverage and service prices. Among them, spirituality is a new factor to be thoughtfully considered due to its significant influence on both the tourist satisfaction and revisit intention. From these findings, we proposed some managerial implications for the sustainable development of rural tourism in An Giang Province by enhancing the satisfaction and revisit intention of the tourists after they visit the province.
The finding of marked geographical variation in HIV prevalence underscores the value of understanding local contexts in the prevention of HIV infection. Although lacking support from data from all provinces, there would appear to be a potential for sex work to drive a self-sustaining heterosexual epidemic. That the close links to serious injecting drug use epidemics can have an accelerating effect in increasing the spread of HIV merits further study.
For 5 years, we have conducted sentinel surveillance for rotavirus at 6 hospitals in 4 cities in Vietnam. Stool samples obtained from >10,000 children <5 years old who were admitted to the hospital with diarrhea have been screened for rotavirus. Overall, 55% of samples were positive, and there was little variability in rates of detection of rotavirus between sites (44%-62%). In Vietnam, the characteristics of rotavirus infection more closely resemble those seen in developed countries, rather than those seen in developing countries: children become infected at an older age, the percentage of stool samples in which rotavirus is detected is extremely high, and the rotavirus strains appear to be the common types, with fewer mixed infections occurring. It is estimated that 5300-6800 children <5 years old die of rotavirus infection each year in Vietnam, representing 8%-11% of all deaths in this age group (cumulative risk per child by age 5 years, 1 in 200 to 1 in 285). Additional studies are ongoing to document the economic cost of the disease and to assess the burden of both fatal cases and milder cases of disease. Study outcomes will provide information for future testing and potential use of a rotavirus vaccine.
The disease burden of rotavirus diarrhea in Vietnam was assessed by surveillance of children <5 years old who were hospitalized for diarrhea at 3 centers in the north and 3 centers in the south. Rotavirus was identified in 56% (range, 47%-60%) of the 5768 patients surveyed between July 1998 and June 2000. G-typing of the first 224 strains indicated that only 2% were non-typeable, 9% were in mixed infections, and the remainder were of the common serotypes G1, G2, G3, G4, and G9. In Vietnam, diarrhea accounts for 9880 deaths per year, which is approximately 15% of all deaths among children <5 years old, or 6.5 deaths per 1000 children. If even 50% of these diarrhea-related deaths in Vietnam were due to rotavirus, the number would represent 4%-8% of all deaths among children <5 years old, 2700-5400 rotavirus-related deaths per year, and 1 death per 280-560 children during the first 5 years of life. Thus, the disease burden of rotavirus in Vietnam is substantial, and programs to encourage the use of oral rehydration should be encouraged while efforts to develop vaccines continue.
This study aims at identifying the influence of corporate social responsibility (CSR) on the competitiveness of tourist enterprises in an emerging tourism region – Mekong Delta in Vietnam with an empirical case of Ben Tre Province. Combining qualitative and quantitative research methods, we conducted a survey of 250 respondents including directors, deputy directors, managing and running tourism businesses. Through statistical tests of scale reliability, exploratory factor analysis, confirmatory factor analysis and structural equation modelling, we found that there are five perspectives of CSR significantly affecting the enterprise competitiveness, including (1) human-oriented CSR, (2) social activity–oriented CSR, (3) partner-oriented CSR, (4) environment-oriented CSR and (5) product and service quality–oriented CSR. Especially, this study identified the important roles of three new elements discovered through our expert interviews and group discussions, including ‘connection between business culture development strategy and the local and native cultures’, ‘tourism products/services promoting local special features’ and ‘tourism products/services promoting green environment’. From these findings, we proposed some managerial implications for policymakers to have proper policies in promoting CSR among tourist enterprises and improving their competitiveness.
There is a high prevalence of gonorrhea/chlamydia among FSWs in these border provinces of Vietnam. Correlates of gonorrhea/chlamydia identified in this study could be incorporated into treatment algorithms for cervicitis in FSWs in Vietnam.
