Objectives: Malaria prevention still faces many difficulties in the mountainous and highland areas, especially the provinces in the Central region and the Central Highlands, Vietnam. This study aims to describe the practice of malaria prevention of forest goers in four high-risk provinces of Vietnam in 2023 and some related factors. Methods: Cross-sectional in 696 foresters in 4 provinces: Gia Lai, Dak Lak, Dak Nong, Binh Phuoc, Vietnam from January 2023 to December 2023. The study used a validated questionnaire and convenience sampling method to select research subjects. Health station staff were trained as data collectors and supervised during data collection. Results: The study subjects with good malaria prevention practices accounted for 54.6%. In addition to sleeping under mosquito nets, subjects also applied other preventive measures such as wearing long-sleeved clothes and mosquito repellant cream, 83.1% and 67.8%, respectively. Gender, ethnicity, religion, education, health insurance, occupation, frequency of work in the forest, and good knowledge about malaria control as it relates to malaria prevention practices. Conclusion: The current status of malaria prevention practices among forest goers in four high-risk provinces is still limited. It is necessary to promote communication measures to improve people's knowledge, attitudes, and practices on malaria prevention

Background: Mosquitoes and pigs play important roles in maintaining and increasing the Japanese Encephalitis (JE) virus in nature and which is then transmitted to humans. Thus, surveillance of the JE infection frequency in the pig population may predict the human JE cases. \r\n', u'Objectives: The study aimed to determine IgG antibody against the JE virus in the pig population in Hanam province \r\n', u'Subjects and methods: The study included 1791 pig serum samples collected from 3 districts of Hanam province from Apr 2006 to Mar 2007. GAC-ELISA technique was used to determine the JE virus infection in the swine population.\r\n', u'Results: The average positive rate in pig population was 34.9 % (626/1791); with the highest frequency occurring in the summer (37.7%- 84.0 %), co-incident with the JE season in Northern Vietnam. On the contrary, in winter JE case are rare, frequency of IgG antibody against JE virus in the swine population was low, ranging from 9.2% to 22.0.%. \r\n', u'Conclusions: These results have shown the ecologically close relationship between the amplification of the JE virus in the swine population, vector and JE cases in northern Vietnam. \r\n', u'

Background: In Vietnam, although there were interventions in perinatal and neonatal care services, the neonatal mortality reduced slowly, accounting for >50% of under-5-year-old mortality rate and >70% of under-1-year-old mortality rate. \r\n', u'Objectives: Discover the status of prenatal, perinatal, and postnatal care services, and analyze the relationships between healthcare services and neonatal mortality in Quang Ninh province. Subjects and method: Information on births and neonatal deaths between January and December 2005 in Quang Ninh province was collected. The perinatal care services including antenatal, delivery and post partum cares were described. The relationship between neonatal deaths and places of delivery was analyzed in order to uncover the risk of death in newborns delivered at home. Results: 76% of pregnant women received 3 or more antenatal care visits. More than 90% of deliveries took place at health facilities, of them, 16% occurred in community health stations. Only 49% of mothers received post partum care visits, with 82% of them received the visits in the first week after delivery. There were 17,519 births and 284 neonatal deaths in 2005. The neonatal mortality rate was lowest in cases born in community health stations (7.5/1.000) and highest in home birth cases (39/1.000). Conclusion: Further improvement in safe motherhood and neonatal survival can be achieved by increasing the accessibility of women to perinatal cares during pregnancy, delivery. \r\n', u'
