BACKGROUND 

The problems with dioxin and its effect to health of the communities have long been discussing during, right after the war and last until now. A number of researches have been implemented with a lot of findings. The latest one, and seems being accepted widely since it has been carried out in collaboration between an well-known research Company in Canada name Hatfield and scientists working in the specific focusing on this narrow field institution in Vietnam called committee 10-80. The approach, the methodology and the ways of collecting samples of this research have been objective and accepted by scientists worldwide through publications and presentations internationally. The results of this study have been quoted in a number of meeting aiming at how to solve problem. Based on the findings of this research, 7 hotspots have been identified with the levels of dioxin vary from as high as 2.5 to 80 time than permitted level (depending on where the sample have been taken) stipulated by a number of countries, and one could easily found out the fact that after more than 30 years of the war, people those who have been and are newly settling in the areas with high concentration of the dioxin still facing with a very high risks of being infected either thru exposing themselves directly with the water, soil where dioxin is settled and indirectly thru daily innocently eating food contaminated by the chemical toxic. Both ways of exposing are not only posing harmful impact directly to the exposed persons but the following generations. Discussions are still going on concerning to the concentrative levels of TCDD in the polluted area. However, under the public health point of view, we could not wait and see of what should be the last decision on the exact levels of TCDD settle in the water, soil and the food chain while community people is still facing day to day with threatening due to a confirmedly higher than permitted levels of dioxin in the polluted materials surrounding them. Some immediate actions should be taken using the scientific approval methods in order to reduce the risks faced by the community people right now.

 DEVELOPING A MODEL OF DENGUE FEVER PREVENTION

The intervention study “Developing a model oF Dengue fever prevention at Binh Thanh Commune, Thanh  Binh District, Dong Thap Province”. Dengue fever/dengue hemorrhagic fever is one of the major health problems in Northern provinces, especially those in the Mekong Delta. In Dong Thap, there is a large number of incidences detected regularly in all seasons during a year. This province also has the highest number of cases in Viet Nam. With the financial and technical support of VPHA, Dong Thap PHA has been implementing this intervention study to deal with this health problem, and then developing a pilot model of replication and adaptation in neighboring regions. This intervention study will be implemented within 28 months, from April  2006 to July 2007, and will be divided into 3 phases:
