| a serological survey of arboviral diseases among the human population of the andaman and nicobar islands, india. | in an attempt to determine the prevalence of certain arthropod-borne viruses of public health importance amongst the human population of the andaman and nicobar islands of india, 2,401 sera were collected from six major localities. the sera were analysed by the hemagglutination inhibition (hi) and neutralization (n) tests, using chikungunya (chik), japanese encephalitis (je), west nile (wn), dengue (den-2), langat (tp-21) and kyasanur forest disease (kfd) viral antigens. the highest prevalence o ... | 2002 | 12757228 |
| community-centred approach for the control of aedes spp. in a peri-urban zone in the andaman and nicobar islands using temephos. | chikungunya fever struck the andaman and nicobar islands in july 2006. from the entomological point of view, dengue and chikungunya are hard to control due to the high prevalence of aedes aegypti in both urban and rural areas. mobilizing communities for the control of aedes aegypti has not been attempted in india. | 2009 | 19764685 |
| dengue: a newly emerging viral infection in andaman and nicobar islands, india. | summaryprior to 2009 dengue fever had not been reported in the andaman and nicobar archipelago. in 2009, a few patients with dengue fever-like illness were reported, some of whom tested positive for dengue antibodies. in 2010, 516 suspected cases were reported, including some with dengue haemorrhagic fever (dhf) and dengue shock syndrome (dss); 80 (15·5%) were positive for dengue antibodies. denv rna was detected in five patients and pcr-based typing showed that three of these belonged to seroty ... | 2011 | 22152648 |

| natural transmission of dengue virus serotype 3 by aedes albopictus (skuse) during an outbreak in havelock island: entomological characteristics. | from may to june 2014, an outbreak of dengue virus (denv) illness occurred in the havelock island, south andaman. entomological investigations were undertaken during the peak of the outbreak, from 26th may-4th june, to identify the primary vector(s) involved in the transmission so that appropriate public health measures could be implemented. adult mosquitoes were collected by bg-sentinel traps in houses and neighborhoods of clinically ill patients. water holding containers were inspected for the ... | 2016 | 26780552 |
| studies on insecticide susceptibility of aedes aegypti (linn) and aedes albopictus (skuse) vectors of dengue and chikungunya in andaman and nicobar islands, india. | dengue and chikungunya are important arboviral infections in the andaman islands. competent vectors viz. aedes aegypti and aedes albopictus are widely prevalent. the most effective proven method for interrupting the transmission of these arboviruses is vector control, mediated through insecticides. currently, ddt and temephos are the insecticides used for vector control in these islands. lack of information on susceptibility necessitated assessing the susceptibility profile of a. aegypti and a. ... | 2015 | 26344869 |
| host-feeding pattern of aedes aegypti and aedes albopictus (diptera: culicidae) in heterogeneous landscapes of south andaman, andaman and nicobar islands, india. | mosquito foraging behavior is a determinant of host-vector contact and has an impact on the risk of arboviral epidemics. therefore, blood-feeding patterns is a useful tool for assessing the role in pathogen transmission by vector mosquitoes. competent vectors of dengue and chikungunya viz. aedes aegypti and aedes albopictus are widely prevalent in the andaman and nicobar archipelago. considering the vector potential, medical importance of both these mosquito species and lack of information on ho ... | 2015 | 26220560 |
| spatial distribution of aedes aegypti and aedes albopictus in relation to geo-ecological features in south andaman, andaman and nicobar islands, india. | the study was undertaken in south andaman district, comprising three tehsils, viz. port blair, ferrargunj and little andaman tehsils, respectively. intensive pupal infestation surveys were carried out along the national highway (nh 223), the main passenger and trade route, referred to as great andaman trunk road. sampling locations at every 3 km were geo-referenced with global positioning system unit. a total of 17314 water collections were examined from 29 locations across the south andaman dis ... | 2017 | 28770695 |
| outbreak investigation of fever mimicking dengue in havelock island, an important tourist destination in the andaman & nicobar archipelago, 2014. | an upsurge of fever cases of unknown origin, but resembling dengue and leptospirosis was reported in havelock, andaman & nicobar islands, an important tourism spot, during may 2014. investigations were carried out to determine the aetiology, and to describe the epidemiology of the outbreak. the data on fever cases attending primary health centre (phc), havelock showed that the average number of cases reporting per week over the last 2 years was 46·1 (95% confidence interval 19·4-72·9). a total o ... | 2017 | 28185603 |
