Dengue fever (DF) is the most rapidly spreading mosquito-borne viral disease in world. In this decade it has expanded to new countries and from urban rural areas. Nepal was regarded DF free until 2004. Since then dengue virus (DENV) its range even mountain regions of Nepal, major outbreaks occurred 2006 2010. However, no data on local knowledge, attitude practice (KAP) exist although such information required for prevention control measures.We conducted a community based cross-sectional...
The Indonesian region of Aceh was the area most severely affected by earthquake and tsunami 26 December 2004. Department Health data reveal an upward trend dengue cases in since events tsunami. Despite increasing incidence region, there is limited understanding among general population Aceh. aim this study to assess knowledge, attitude, practice (KAP) regarding people Aceh, Indonesia order design intervention strategies for effective prevention program. A community-based cross-sectional...
Abstract Aim We used inferences of phylogenetic relationships and divergence times for three lineages highland pitvipers to identify broad‐scale historical events that have shaped the evolutionary history Middle American taxa, test previous hypotheses Neotropical speciation. Location America (Central Mexico). Methods 2306 base pairs mitochondrial gene sequences from 178 individuals estimate phylogeny New World pitviper lineages, focusing on genera ( Atropoides , Bothriechis Cerrophidion )...
Background The presence of the recently introduced primary dengue virus vector mosquito Aedes aegypti in Nepal, association with likely indigenous secondary albopictus, raises public health concerns. Chikungunya fever cases have also been reported and causing this disease is transmitted by these species. Here we report results a study on risk factors for chikungunya vectors, their elevational ceiling distribution, climatic determinants abundance central Nepal. Methodology/Principal Findings...
Poisoning after eating puffer fish containing highly lethal tetrodotoxin (TTX) is widespread in Asia. In 2008, naïve inland populations Bangladesh were exposed to cheap sold on markets. three outbreaks, 141 patients with history of consumption hospitalized. Symptoms poisoning included perioral paraesthesia, tingling over the entire body, nausea and vomiting, dizziness, headache, abdominal pain muscular paralysis limbs. Seventeen (12%) died from rapidly developing respiratory arrest. Blood...
Ever since it was discovered that zoophilic vectors can transmit malaria, zooprophylaxis has been used to prevent the disease. However, zoopotentiation also observed. Thus, presence of livestock widely accepted as an important variable for prevalence and risk but effectiveness remained subject debate. This study aims critically analyse effects on malaria using a large dataset from Indonesia. is based data Indonesia Basic Health Research (“Riskesdas”) cross-sectional survey 2007 organized by...
Snakebite envenoming is a common but neglected public health problem, particularly in impoverished rural regions of sub-Saharan Africa, Asia and Latin America. The only validated treatment for this condition passive immunotherapy with safe effective animal-derived antivenoms. However, there long-lasting crisis the availability these life-saving medications, Africa parts Asia. We herein advocate multicomponent strategy to substantially improve antivenoms at global level. This based on: (i)...
Malaria, a parasitic infection, is life-threatening disease in South Sumatra Province, Indonesia. This study aimed to investigate the spatial association between malaria occurrence and environmental risk factors. The number of confirmed cases was analysed for year 2013 from routine reporting Provincial Health Office Sumatra. were spread over 436 out 1613 villages. Six potential ecological predictors different regions using ordinary least square (OLS) geographically weighted regression (GWR)....
Regional collaboration is crucial to end preventable deaths and disability from snakebites in South Asia, say Ravikar Ralph colleagues ### Key messages Five million occur globally each year, causing between 81 000 138 nearly 400 amputations other permanent disabilities.1 Asia has the highest incidence of venomous world.2 Within region, Bangladesh, India, Nepal, Pakistan, Sri Lanka together constitute 70% global snakebite mortality.3 The World Health Organization recognised as a neglected...
Hepatitis B (HepB) is a major public health concern in Malaysia yet little known about knowledge and awareness of this infection the country. Such information essential for designing effective intervention strategies HepB prevention control. The aim study was to characterize regarding identify their associated sociodemographic determinants. A community-based cross-sectional survey conducted between January May 2016 Selangor state Malaysia. two-stage cluster random sampling design used one...
Malaria is an increasing concern in Indonesia. Socio-demographic factors were found to strongly influence malaria prevalence. This research aimed explore the associations between socio-demographic and prevalence The study used a cross-sectional design analysed relationships among explanatory variables of five endemic provinces using multivariable logistic regression. analysis baseline data revealed following independent risk related prevalence: gender, age, occupation, knowledge availability...
Since 2006, Nepal has experienced frequent Dengue fever (DF) outbreaks. Up to now, there have been no knowledge, attitude and practice (KAP) studies carried out on DF in that included qualitative in-depth quantitative data. Thus, we aimed explore compare the KAP of people residing lowland (< 1500 m) highland (> areas Nepal.A cross-sectional mixed-method study was conducted six districts central September-October 2018 including both (660 household surveys) data (12 focus group discussions 27...
Over the last decade, incidence of confirmed malaria has declined significantly in Nepal. The aim this paper is to assess spatio-temporal distribution and its association with climatic factors vector control interventions two high-risk districts
Rapidly increasing temperatures in the mountain region of Nepal and recent reports dengue fever lymphatic filariasis cases from mountainous areas central prompted us to study spatio-temporal distribution vectors these two diseases along an altitudinal transect Nepal.We conducted a longitudinal four distinct physiographical regions September 2011 February 2012. We used BG-Sentinel CDC light traps capture adult mosquitoes. found geographical virus Aedes aegypti albopictus our extend up 1,310 m...
It is increasingly recognized that climate change can alter the geographical distribution of vector-borne diseases (VBDs) with shifts disease vectors to higher altitudes and latitudes. In particular, an increasing risk malaria dengue fever epidemics in tropical highlands temperate regions has been predicted different scenarios. The aim this paper expand current knowledge on seasonal occurrence altitudinal other eastern Nepal. Adult mosquitoes resting indoors outdoors were collected using CDC...

The Hindu Kush Himalayan region is a global hotspot for climate change and highly vulnerable to its direct indirect impacts. Understanding people’s perception of crucial effective adaptation strategies. We conducted study by using quantitative (Household survey, n = 660) qualitative data collection tools (Focus group discussion, 12; In-depth interviews, 27) in central Nepal encompassing three altitudinal regions: Lowland (<1000 m amsl; Terai region), Midland (1000–1500 hilly region)...
Prospective studies of snake bite patients in Chittagong, Bangladesh, included five cases bites by greater black kraits (Bungarus niger), proven examination the snakes that had been responsible. This species was previously known only from India, Nepal, Bhutan and Burma. The index case presented with descending flaccid paralysis typical neurotoxic envenoming all Bungarus species, but later developed generalized rhabdomyolysis (peak serum creatine kinase concentration 29 960 units/l)...
