An evaluation of the current coverage and diminished rate of mosquito nets usage for malaria control plays an important role in malaria control planning. A survery was carried out between 1995 and 2003 in 15 hamlets of five communes of 3 malaria endemic districts in Thua Thien – Hue province. A high rate of bed-net usage was found in the surveyed hamlets. In average, the coverage reached the rate of 2.0 ± 0.3% nets per person. However a considerable rate of damaged nets (4.7 ± 1.2%) was also recorded in the surveys. Further surveys and studies should be conducted to determine the ways the bed-nets go down and get diminished for planning of more appropriate malaria control measures

Data research from 1997-2004, restrospective and cross-sectional studies were conducted every 6 months from 4/2002-4/2004 to collect data on malaria patients and the rate of malaria parasite and follow up the sectoral development of Anopheles and An. minimus at areas where interruption of vector prevention at different times: 1, 2 or 3 years showed that indicators like malaria patients, malaria patients/1000 residents and the density of malaria parasite were decreasing and stable. An.minimus recovers and increase with time. The density at 2-3 years after spraying was higher than the density at the point of spraying. An.minimus presented at all sites of the study but the density in striking people was low. If the supervision, management and treatment of malaria patients are well, the malaria situation could be kept stable even vector control methods were not used often

Background: National malaria preventive and control program is rather successful, but the special result has not been accurately analyzed.\r\n', u'Objectives: to evaluate of the malaria situation for the period of 2000-2007 in Viet Nam.\r\n', u'Subjects and methods: This retrospective study analyzed data from malaria information system.\r\n', u'Results: On annual average, about 140.000 to 150.000 patients are diagnosed as malaria. Annual malaria morbidity is greatly reduced from 6.91/1000 in 2000 to 2.21/ 1000 population in 2007. The deaths in children accounted for 30 to 40% of the total malaria deaths of the whole country. The annual average number of malaria cases treated is about 150.000 to 160.000 and it is decreased by year. Artemisinine based Combination Therapy (ACT) for P.falciparum cases is 18 - 20% of the total patients. \r\n', u'From 2000 to 2007, on average, about 1.5 to 2 million of people in the malaria endemic, high risk areas were protected by Indoor Residual Spray (IRS) annually. The coverage of protected population tends to be reduced from 6.7% to 5.9 % of population at risk of malaria. \r\n', u'The annual average number of population protected by Insecticide Treated Bed Nets (ITNs) is from 8.5 to 11.5 million and the coverage of ITNs is increasing from 23.6% to 31.0% of population in malaria endemic areas. . \r\n', u'Conclusion:From 2000 to 2007, the malaria in Vietnam continues to be decreased in term of morbidity and mortality.\r\n', u'

Clothers with hats and mosquito nets made from Olyset tried on 50 people who were working out-door at nights and 50 people who were sleeping with mosquito nets indoor at nights. 100 control people divided into 2 groups. Results showed that mosquito density indoor decreased significantly, clinical malaria and malarial parasite reduced from the 2nd month to the 4th month. There was no case of clinical malaria and malaria parasite on the 5th month. There was no major change in the control groups before and after experiment. After 7 to 10 months of experiment, no major changes of falling mosquito (80%) when contacted with Olyset net within three minutes

An evaluation of the malaria control activity in 2000 has shown that the malaria control activity has obtained some achievements including no big outbreak, reduction of morbidity number and mortality number to 50% and 60%, respectively when comparing with these in 1995. This paper presented some shortcoming such as the high morbidity and mortality, malaria in the central highland, limited diagnosis, treatment, education and communication in the local level, especially in remote areas as well as unstable equipment and material

In past ten years, the socialized activity has contributed an important part in improving the malaria situation of VietNam, with remarkable achievements are: after 10 years (1991-2000), the malaria mortality reduced by 96.8%, malaria incidence reduced by 73%. Malaria outbreaks reduced by 98.6% and many locals have created sustainable factors to maintain the result of malaria control

From 1991, the Vietnam has been implementing the National malaria control program aiming at the reduction of outbreak, morbidity and mortality. This program has obtained some primary achievements including interruption of malaria outbreak, reduction of malaria epidemy, and morbidity and mortality

An investigation on 31 communes at Thua Thien - Hue province, with the total of 116 times of investigations had collected 29 species of Anopheles mosquitoes with 2 varitae: Anopheles Meigen, 1818 (10 species) and Cellia Theobald, 1902 (19 species). The predominant species were An. Sinensis, An. Aconitus and An. Philippinensis. 2 major mosquito vectors were An.dirus and An. Minimus, however they accounted for low rates

National Institute of Malariology - Parasitology - Entomology reported national malaria status in the first 6 months of 2004. Investigative indexes included: mortality, morbidity, the shortcomings of technology, natural environmental and social changes, resource management. Providing some focuses on malaria prevention in the second 6 months of 2004 for malaria epidemiological surveillance, vecto prevention, malaria treatment and diagnosis, communicative education and malaria preventive socialization

In 2003, due to practice effectively malaria prevention programs and intensify supervise malaria epidemiology that malaria prevention in Tuyen Quang provice had good results, gained 3 aims: malaria morbidity reduced 28%, malaria mortality 0%. Malaria epidemiology was stable in Tuyen Quang. However, in 15 malaria parasites in Tuyen Quang in 2003, there was 14 was exotic malaria parasites from the South and other provinces. Therefore, in the later years, beside the investigation, management of Ministy of Health, the government project for malaria prevention, National Institute of Malariology - Parasitology - Entomology, Tuyen Quang needed to implement well malaria epidemiological surveillance in basic levels and malaria preventive plan to maintain gained malaria preventive results
