Socailize has important role in building and developing malaria prevention factors in Thua Thien - Hue province. The union, industries have had the specific activities to help socializing effectively malaria prevention acitivity. The results: 100% household sleeping with net. 92.1% of nets available is used and 96.25% of population has knowledge sleeping with net. To socailize effectively malaria prevention activity, in the next time, need to maintain and develop these contents: To promote the role and leader responsibility, population guidance of leaders; To mobilize society contributing the more and more for malaria prevention; To propagate widely to organizations, government and people knowledging the necessary to socialize; To mobilize the economic contribution; To diversify the forms and practical solutions

Reprospective study on the healthy station's reports and the data monthly of Malaria Protection Centre of Thanh Hoa province, from 1998-2002. The malaria situation has been stable, no malaria epidemic outbreak and death due to malaria. The annual malaria morbidity has been greatly reduced from 3.74% in 1998 to 2.09% in 2001 and 1.70% in 2002. The malaria parasite rate has been reduced from 0.25% in 1998 to 0.22% in 2001 and 0.19% in 2002. The malaria imported cases were 51.78% (1998) and 92.86% (2002). However, malaria cases are available in almost districts. The number of positive cases in the plain and midland districts are more than in the mountainous area due to the importation of malaria from malaria endemic areas. The malaria cases distributed scattered, which is difficult for management and treatment patients

In the first 7 months of 2002, the malaria status in Bac Can province were rather stable: the malaria incidence reduced 16%, there was no malaria outbreak, the morbidity due to malaria reduced. These activities to practice the malaria prevention plan in Bac Can: supervising malaria epidemiology, preventing vecto, propagating healthy education, educating training, systemizing report information, using materials expenses. The result of survey quality malaria prevention activities in Cho Moi and Mach Thong districts were low: Bach Thong district examined newly supplement smear pills, in which smear pill had more mistakes; Cho Moi district treated correctly 50% of checked case history

In December 2002, 445 households and 1832 individuals of Khanh Trung commune were interviewed and examined in a cross-sectional survey (approximately 85% inhabitants of the commune). The results showed that: The slide positive rate was 10.1%. The rate of asymptomatic malaria carriers was 77.2% of total malaria confirmed cases. There is a relation between people with sleeping in the forest and people without sleeping in its, OR=1.89, P=0.001. Ethnic group of Ra-glai infected with malaria (11.1%) and the age group which had highest rate of asymptomatic malaria was 5-9 years old 11.2%. Parasite density index of asymptomatic malaria group was lower than that of the fever malaria group

There were 1.000 people (accounting for 43% of population) received blood slide examination in Thanh commune, Huong Hoa district, Quang Tri province, from 10/10/2002 to 15/12/2002. Of which 170 people got malaria parasites with 84 cases of single P.falciparum infection, 46 cases of single P.vavax infection and 40 cases of mix infection P.vivax + P.falciparum. The rate of malaria infection in children under 14 years old was high (67.6%). The cure rate of 51 patients with uncomplicated P.falciparum malaria received SR2 ( a single dose of 25mg sulfadoxine + 1.25 mg pyrimethamine/kg) by day 28 was 87.7%. In this survey, 532 people were received Paracheck-Pf and bloot slides examination by microscope. The results showed that 101 cases were found to be positive(+) with Paracheck-Pf. Of which 87 cases (86.1%) with P.falciparum were found by blood slide examination and 14 cases (13.9%) were negative

The supervision on the quality of malaria diagnosis and treatment was carried out at 7 provincial and central hospitals, 18 distric hospital in the Central and Highland area, from 2000 to 2002. The answer of the results of examination of malaria parasite available before 2 hours was 73.7%; no blood examination for malaria parasite was 6.0%, the rate of mistakes in parasitic examination was 6.1%. Diagnosis of malaria cases taken before 2 hours was 82.9% and correct diagnosis of malaria cases was 80.1%. The treatment with specific antimalarial drugs occupied 69.7%. Most of clinical malaria cases were treated by combination of some specific antimalarial drugs and antibiotic. The provincial and central hospitals have proper facilities and anti-malaria drugs to for treatment of all forms of malaria. The district hospitals have not yet got sufficient facilities for emergency aid and treatment of severe and complicated malaria such as severe complications, severe anaemia malaria

The retrospective study on the quality of malarial diagnosis and treatment in 4 district hospitals of Dac Lac province in 2001. Quality of malarial diagnosis: 100% patients tested for malaria, the positive slide rate was 58.3%, of which 93.1% with P.falciparum infected. Cases defination of WHO to confirm malaria diagnosis was not applied. There were 4 types of malaria diagnosis: malaria 26.8%, clinical malaria 28.8%, P.falciparum malaria 37.5% and severe malaria cases 6.0%. Quality of treatment: there were 8 treatment schedules used, of which 7 schedules were used for treatment of P.falciparum infection. More than 70% of the patients received treatment schedule with artemisinin derivatives and 66.6%-80% of them received full dose of treatment. The average time of treatment course was 2.5-4.5% days

In 2002, 99.807 blood slides were taken and examined in Thanh Hoa province, of which 33.464 slides were taken from fever patients (33.52%). 196 positive cases were detected. 52 microscopic points were checked, of which 10 microscopic points were very good functioning (19.23%), 27 points were good (59.9%), 12 were average and 3 were not good (5.76%). The quality of slides taken by the commune and village health workers was not so good, the slides were too thick or too thin with blood. In some villages, the slides were taken massively in order to fulfill the target. Checking the quality of microscopy showed that the mistake rate of microscopy was 13.16% as compared with the total slides sent for rechecking. In some microscopic points, the mistake rate was high (the provincial hospital had the mistake of 6/19 positive slides)

Cross-sectional survey on the effectiveness of the Parascheck Pf tests for malaria rapid diagnosis was carried out in all people lived in malaria areas in the Central and Highland of Vietnam. Comparision of the sensitivity, the specificity, the value of negative prediction and the accuracy of the Paracheck Pf tests between 4 different geographical zones and 2 different malaria areas (stable and unstable malaria areas) showed that there was no significant difference. The rapid Paracheck Pf tests have the sensitivity, specificity, the value of positive and negative prediction and the accuracy of 95.8%, 98.1%, 74.3%, 99.7% and 97.9%, respectively

Application of PCR technique to survey component and mechanism of 4 human malaria parasites in Gia Lai province. These used bait couples were specificity for P.falciparum, P.vivax, P.malariae and P.ovale. The results showed that: there were the existance of 4 human malaria parasite species, of which P.falciparum was 57.6%, combination rate of 2,3,4 parasites species was 54.76%. To distinguish the recurrent, re-infection based on the difference of alleles in locus gen. 3 genes for highly polymorphic antigens: merozoite surface protein 1 (MSP1), merozoite surface protein 2 (MSP2), glutamate rich protein (GLURP). 11 patients were treated by fansidar had been recurrented after 14 days
