Introduction: Dengue is the most prevalent viral mosquito-borne disease, with over 2.5 billion humans at risk given its endemicity in not less than 100 countries. Globally, 50-100 million cases of dengue is seen annually, with approximately 0.7% resulting in Dengue Hemorrhagic Fever (DHF), and 22,000 deaths. In 2017, there were 83,849 reported cases of dengue fever in endemic under-reported Malaysia, with 177 deaths. Method: The Authors here narrate from their own personal-experiences, besides reviewing existing-literature. Results and Conclusion: Prevention and Control methods have been desiring of greater achievements, but also show greater promise with Newer Insecticides, Innovative Methods and Vaccines. Dengue Fever would very likely become near-eradicated just like all other vaccine-preventable diseases, once comprehensive mass-vaccination programs are available globally, using safe and very-effective tetravalent-vaccines soon to be available.

Globally, 50-100 million cases of dengue occur annually, with approximately 0.7% resulting in dengue haemorrhagic fever (DHF), and 22,000 deaths. In 2017, there were 83,849 reported cases of dengue fever in endemic under-reported Malaysia, with 177 deaths. One of our authors (Verasingam K 2006) here, earlier published an article in the Med J Malaysia titled “Dengue Fever in Malaysia: Time for Review?” This Article is meant as a sequel. Method: The Authors here narrate from their own personal-experiences, as well as from reviewing existing-literature. Results and Conclusion: Clinical Management has brought about vast improvements in mortality and morbidity. Similarly, great advancements in Laboratory Diagnostics. Prevention and Control methods have been desiring of greater achievements, but also show greater promise with Newer Insecticides, Innovative Methods and Vaccines. Dengue Fever would very likely become near-eradicated just like all other vaccine-preventable diseases, once comprehensive mass-vaccination programmes are available globally, using safe and very-effective tetravalent-vaccines soon to be available.

SUMMARY Dengue fever, a very old disease, has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors, increased epidemic activity, the development of hyperendemicity (the cocirculation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tropical infectious disease after malaria, with an estimated 100 million cases of dengue fever, 500,000 cases of dengue hemorrhagic fever, and 25,000 deaths annually. The reasons for this resurgence and emergence of dengue hemorrhagic fever in the waning years of the 20th century are complex and not fully understood, but demographic, societal, and public health infrastructure changes in the past 30 years have contributed greatly. This paper reviews the changing epidemiology of dengue and dengue hemorrhagic fever by geographic region, the natural history and transmission cycles, clinical diagnosis of both dengue fever and dengue hemorrhagic fever, serologic and virologic laboratory diagnoses, pathogenesis, surveillance, prevention, and control. A major challenge for public health officials in all tropical areas of the world is to devleop and implement sustainable prevention and control programs that will reverse the trend of emergent dengue hemorrhagic fever.

Dengue fever, a very old disease, has re-emerged during past 20 years besides, an expanded geographic distribution of both the viruses and the mosquito vectors. With increased epidemic activity, the development of hyperendemicity (the co-circulation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease was the most important tropical infectious disease after malaria, with an estimated 100 million cases of dengue fever, 500,000 cases of dengue hemorrhagic fever, and 25,000 deaths annually. The reasons for this resurgence and emergence of dengue hemorrhagic fever in 21st century are complex and not fully understood, but demographic, societal, and public health infrastructure changes in the past 30 years have contributed greatly. Based on the data of National Vector Borne Disease Control Programme (NVBDCP), the number of cases reported in 2016 in India was about 1,11,880 for dengue with 227 deaths1. This paper reviews the changing epidemiology of dengue and dengue hemorrhagic fever by geographic region, the natural history and transmission cycles, clinical diagnosis of both dengue fever and dengue hemorrhagic fever, serologic and virologic laboratory diagnoses, pathogenesis, surveillance, prevention, and control. Major challenges for public health officials in all tropical areas of the world is to develop and implement sustainable prevention and control programs that will reverse the trend of emergent dengue hemorrhagic fever.

Dengue fever is a painful mosquito-borne infection caused by different types of virus in various localities of the world. There is no particular medicine or vaccine to treat person suffering from dengue fever. Dengue viruses are transmitted by the bite of female Aedes (Ae) mosquitoes. Dengue fever viruses are mainly transmitted by Aedes which can be active in tropical or subtropical climates. Aedes Aegypti is the key step to avoid infection transmission to save millions of people in all over the world. This paper provides a standard guideline in the planning of dengue prevention and control measures. At the same time gives the priorities including clinical management and hospitalized dengue patients have to address essentially.

Abstract Background Dengue is a mosquito-borne flavivirus present in many metropolitan cities of tropical countries. Methods During and after the dengue season (September 2018 to January 2019), we conducted a case-control study in order to determine the risk factors for dengue fever in Hanoi city, Vietnam. 98 dengue patients and 99 patients with other acute infections, such as Hepatitis B virus infection, were recruited at Department of Infectious Disease of Bach Mai national hospital in Hanoi. Patients were interviewed using a structured questionnaire covering demographic, housing, environmental factors and knowledge, attitude, and practice on dengue prevention and control. Univariate analysis and multivariable logistic regression were used to determine the risk factors of dengue status. Results The mean score of knowledge items and practice items was only 7.9 out of total 19 points and 3.9 out of total 17 points, respectively. While the mean score of attitude items was 4.8 out of total 6 points. Multivariable logistic regression indicated that older patients had lesser risk of getting dengue infection as compared to younger adults aged 16–30, and patients living in peri-urban districts were less likely to suffer of dengue fever than patients living in central urban districts (OR = 0.31; 95% CI 0.13–0.75). This study could not find any association with occupation, water storage habit, knowledge, attitude, or practice on dengue prevention. Conclusions All patients had a relatively low level of knowledge and practice on dengue prevention and control. However, the attitude of the participants was good. We found that age group and living district were the risk factors correlated with the dengue status. Communication programs on raising dengue awareness should be repeated all year round and target particular groups of adolescents, younger adults, landlords and migrants from other provinces to improve their knowledge and encourage them to implement preventive measures against dengue fever.

Dynamic Damage

To provide a theoretical basis for water prevention and control methods and reasonable supporting techniques for vertical shaft, and to ensure the shaft construction to pass the sandstone aquifer safely and rapidly, numerical simulation using dynamic damage constitutive model, which was a user-defined constitutive modules in FLAC3D, a lagrangian analysis code in three dimensions, has been applied to investigate the dynamic damage effect in the surrounding rock of the grouting curtain near the driving working face for vertical shaft excavated by blasting. The results indicate that the distribution of the damage zone in the surrounding rock of the shaft, which decreases the effective thickness of the grouting curtain, was like a ellip-se, and that the depth of the damage zone in the surrounding rock of the shaft grouting curtain is fewer than that of the driving face floor. It can be concluded that the centre part of the driving face floor, especially the cutting hole zones, and the shaft wall in the greater horizontal stress side are the " key parts " for shaft water prevention and control methods.

Epidemiological Characteristics

We assessed the epidemiological characteristics of a mumps virus epidemic (genotype D) that occurred in the Netherlands between August 2007 and May 2009 and its association with a subsequent mumps outbreak in Canada. In the Netherlands, five data sources were used: notifications (only mandatory since the end of 2008) (56 cases), laboratory confirmation data (177 cases), a sentinel general practitioner (GP) database (275 cases), hospitalisation data (29 cases) and weekly virological reports (96 cases). The median age of cases in the notification, laboratory and GP databases ranged from 13 to 15 years. The proportion of cases that were unvaccinated ranged from 65% to 85% in the notification, laboratory and GP databases. Having orthodox Protestant beliefs was the main reason for not being vaccinated. In Canada, a mumps virus strain indistinguishable from the Dutch epidemic strain was detected between February and October 2008 in an orthodox Protestant community with historical and family links to the affected community in the Netherlands, suggesting that spread to Canada had occurred. Prevention and control of vaccine-preventable diseases among population subgroups with low vaccination coverage remains a priority.

Hemorrhagic fever with renal syndrome(HFRS) is a worldwide fulminant infectious disease. Since the first HFRS cases in Hubei Province were reported in 1957, the disease has spread across the province and Hubei has become one of seriously affected areas in China. However, the epidemic characteristics of HFRS are still not entirely clear. Therefore, a systematic investigation of spatial and temporal distribution pattern of HFRS system is needed. In order to facilitate better prevention and control of HFRS in Hubei Province, in this paper, a GIS spatiotemporal analysis and modeling tool was developed to analyze the spatiotemporal dynamics of the HFRS epidemic, as well as providinga comprehensive examination the dynamic pattern of HFRS in Hubei over the past 30 years (1980-2009), to determine spatiotemporal change trends and the causes of HFRS. This paper describes the experiments and their results.

The increasing cases of dengue hemorrhagic fever disease in both children and adults can beinfluenced by several factors. One of that influences increasing of dengue fever is lack of communityknowledge about dengue hemorrhagic fever. Brainstorming is a form of discussion to gather theinformation from all participants. This research was to find out the effect of health educationbrainstorming method and video toward knowledge of dengue fever in the work area of Puger PublicHealth Center the distric of Jember. This was a quasy experiment research with two groups pretestposttesttreatment design. The population were 88 families with 30 respondents as sample,conducted by simple random sampling, and divided into two groups 15 respondents as treatmentgroup and 15 respondents as control group. Treatment group got health education brainstormingmethod combined with video and control group got health education brace method. Data wereanalyzed used t-test dependent and t-test independent with 95% CI (α: 0,05). The result showedthere were significant differences of knowledge before and after in both treatment group and controlgroup (p: 0,000) and there were significant differences between treatment group and control afterhealth education (p: 0,001). Overall, health education by brainstorming method and can improveknowledge of dengue hemorrhagic fever. It is recommended for nurses to do health educationpreventation and treatment about dengue hemorrhagic fever to improve knowledge people.Keywords: health education brainstorming method and video, knowledge, dengue hemorrhagicfever
