Purpose The purpose of this paper is to investigate epidemiology and control strategies of the four priority vector-borne diseases (VBDs) in Nepal, i.e. malaria, Kala-azar (visceral leishmaniasis), lymphatic filariasis (LF) and dengue fever/dengue hemorrhagic fever. Design/methodology/approach The study was a retrospective design to collect data during 1998–2016 from VBDs endemic districts of Nepal. All data were reviewed and epidemiological information of the four VBDs were analyzed. Findings The number of malaria cases during 1998–2016 of the 13 affected districts was declined from 8,498 to 991 cases with no record of deaths since 2012. The number of cases and deaths in the 12 kala-azar (visceral leishmaniasis) affected districts in 1998 was 1,409 and 42 cases, respectively, but was dramatically decreased in 2016 to 213 and 2 cases, respectively. LF cases of the 61 affected districts in 2011, 2014 and 2016 were 28,855, 30,000 and 33,517 cases, respectively. In total, 25 districts achieved elimination target and the remaining are expected to complete the needful cycles by 2018. Dengue incidence of the 31 affected districts during 2006–2015 was under controlled with reported cases of 642, 356 and 136 cases in 2013, 2014 and 2015, respectively, and only one death in 2015. Implementation of control strategies particularly disease management and community peoples’ awareness significantly reduced the cases and deaths of the target VBDs. Practical implications The results of this study clearly suggest that the current control strategies have been worked effectively. However, in particular of the VBDs, health education in communities in the endemic areas should be adopted for better community participation in the context of the primary health care approach and increase the effectiveness of disease control. Originality/value VBDs, i.e., malaria, kala-azar (visceral leishmaniasis), LF and dengue fever/dengue hemorrhagic fever, are major causes of morbidity and mortality in the least developed countries which include Nepal. Globalization of travel and trading, unplanned urbanization, environmental and climate change are having a significant impact on disease transmission. Therefore, the Ministry of Health of Nepal had brought some changes in strategies based on activities for disease control, vector control, preventive and preparedness for outbreak response. Consequently, the cases and deaths due to malaria, kala-azar (visceral leishmaniasis), lymphatic filaiasis and dengue fever/dengue hemorrhagic fever have been brought down markedly.

Abstract Background Wolbachia is an obligate intracellular maternally transmitted, gram-negative bacterium which forms a spectrum of endosymbiotic relationships from parasitism to obligatory mutualism in a wide range of arthropods and onchocercid nematodes, respectively. In arthropods Wolbachia produces reproductive manipulations such as male killing, feminization, parthenogenesis and cytoplasmic incompatibility for its propagation and provides an additional fitness benefit for the host to protect against pathogens, whilst in onchocercid nematodes, apart from the mutual metabolic dependence, this bacterium is involved in moulting, embryogenesis, growth and survival of the host. Methods This review details the molecular data of Wolbachia and its effect on host biology, immunity, ecology and evolution, reproduction, endosymbiont-based treatment and control strategies exploited for filariasis. Relevant peer-reviewed scientic papers available in various authenticated scientific data bases were considered while writing the review. Conclusions The information presented provides an overview on Wolbachia biology and its use in the control and/or treatment of vectors, onchocercid nematodes and viral diseases of medical and veterinary importance. This offers the development of new approaches for the control of a variety of vector-borne diseases. Graphic Abstract

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

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.

Abstract BackgroundDengue and chikungunya (CHIKV) are the two major vector-borne diseases of serious public health concern in India. Studies on socio-economic and housing determinants of dengue and CHIKV at a pan-India level are lacking. Here, we took advantage of the recently carried out Longitudinal Ageing Study in India (LASI) carried across all the States and Union Territories of India to study the social determinants of dengue and CHIKV in India.MethodsLASI-1 (2017-2018) data on the self-reported period prevalence of dengue and CHIKV from 70,865 respondents aged ≥45 years were used for this analysis. The State-wise distribution of dengue and CHIKV was mapped. Prevalence was estimated for each study variable, and the difference was compared using the χ2 test. The adjusted odds ratios (AOR) of the socio-economic and housing variables for dengue and CHIKV were calculated using a multiple logistic regression model.ResultsUrban residence is the major socio-economic determinant of dengue and CHIKV (dengue: AOR: 1.57, 95% CI: 1.17-2.10; CHIKV: AOR 1.56, 95% CI: 1.20-2.02). Wealth status (richest) and less than primary schooling are associated with dengue and CHIKV prevalence. In addition to these factors, social group (scheduled and forward castes) is also associated with CHIKV prevalence. Water-source outside the dwelling (AOR: 1.20, 95% CI: 0.96-1.50), pucca or semi- pucca house type are also associated with increased odds of CHIKV. ConclusionsDespite the limitation that the data is only from adults ≥ 45, this analysis provides important insights into the socio-economic and housing variables that increase the odds of dengue and CHIKV in India. Understanding these determinants may assist in the national planning of prevention and control strategies for dengue and CHIKV.

ABSTRAK  Latar belakang: Demam Berdarah Dengue (DBD) disebabkan oleh virus Dengue dapat menyebabkan kematian. Pencegahan DBD yang dianggap paling tepat adalah Pemberantasan Sarang Nyamuk (PSN). Penelitian ini bertujuan untuk mengetahui pengaruh pelatihan pengendalian vektor Demam Berdarah pada siswa sekolah dasar terhadap Maya Index di Majalengka. Metode: Penelitian ini menggunakan desain quasi experiment (pretest-posttest control group design). Sebanyak 4 sekolah terpilih sebagai kelompok intervensi dan 4 sekolah lainnya sebagai kontrol. Subyek penelitian adalah siswa kelas IV-VI yang terdiri dari 171 siswa pada kelompok intervensi dan 163 pada kelompok kontrol. Instrumen yang digunakan adalah formulir pemantauan jentik berkala. Hasil: Jumlah rumah dengan kategori Maya Index tinggi berkurang dari 27,5% menjadi 9,4%. Terjadi penurunan angka BRI kategori tinggi pada kelompok intervensi dari 20,5% menjadi 1,8%. Pada kelompok kontrol tidak terjadi penurunan angka BRI kategori tinggi (22,1%), sebaliknya terjadi penurunan kategori rendah dari 34,4% menjadi 3,7%. Tidak terjadi penurunan angka HRI pada kelompok intervensi maupun kontrol. Kesimpulan: Pelatihan pengendalian vektor Demam Berdarah dapat menurunkan nilai BRI dan Maya Index, tetapi tidak berpengaruh terhadap nilai HRI. Tidak adanya perubahan nilai HRI menunjukkan bahwa kebersihan dan sanitasi lingkungan merupakan faktor yang berpengaruh terhadap probabilitas kejadian demam berdarah. Kata Kunci : Demam Berdarah, Maya Index, pelatihan, pengendalian vektor   ABSTRACT Background: Dengue Hemorrhagic Fever (DHF) caused by Dengue virus could cause death. The most appropriate prevention of Dengue is eradication of mosquito nests (PSN). This study aims to determine the effect of Dengue vector control training on elementary students towards Maya Index in Majalengka. Method: This study used quasi-experimental design (pretest-posttest control group design). A total of 4 schools were selected as intervention groups and 4 other schools as controls. The subjects were students in grades IV-VI consisting of 171 students in the intervention group and 163 in the control group. The instrument used was periodic larva monitoring form. Results: The number of houses with a high Maya Index category in the intervention group decreased from 27.5% to 9.4%. There was a decrease in the high BRI category in the intervention group from 20.5% to 1.8%. In the control group, there was no decrease in the high BRI category (22.1%), on the contrary, there was a decrease in the low category from 34.4% to 3.7%. There was no decrease in HRI rates both of intervention or control groups. Conclusion: Dengue Fever vector control training could decrease the value of BRI and Maya Index, but does not affect the value of HRI. The absence of changes in HRI  indicate that environmental hygiene and sanitation are factors that influence the probability of dengue fever occurrence. Keywords: Dengue Hemorrhagic Fever, Maya Index, training, vector control
