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

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

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

The infection of malaria fell down by 30,9% (in quantity) and 26.3% (rate of population). It is the first time for many years, the mortality and the infection rate of malaria in the year on year basic in Tay Nguyen - Binh Phuoc areas reached lower level compared with the whole country. The main causes as followed: There were time by instructions from the Ministry of Health's leaders; The national project on malaria prevention, the Institutes for malaria - parasite - insect.
