| susceptibility of immature stages of aedes (stegomyia) aegypti; vector of dengue and chikungunya to insecticides from india. | susceptibility of aedes aegypti to some insecticides in different geographic areas was conducted during dengue and chikungunya outbreak. at present, the only method of preventing dengue and chikungunya is to control the vector, which is the weakest link in vector-borne diseases. in our study, the susceptibility of a. aegypti collected from urban areas of delhi, mumbai, jodhpur, chennai and coimbatore was evaluated against temephos, fenthion, malathion and ddt. the a. aegypti from different locat ... | 2008 | 18172687 |
| co-infections with chikungunya virus and dengue virus in delhi, india. | aedes aegypti mosquitoes are common vectors for dengue virus and chikungunya virus. in areas where both viruses cocirculate, they can be transmitted together. during a dengue outbreak in delhi in 2006, 17 of 69 serum samples were positive for chikungunya virus by reverse transcription-pcr; 6 samples were positive for both viruses. | 2009 | 19624923 |

| genetic characterization of chikungunya virus from new delhi reveal emergence of a new molecular signature in indian isolates. | chikungunya (chik) is currently endemic in south and central india and exist as co-infections with dengue in northern india. in 2010, new delhi witnessed an outbreak of chik in the months october-december. this was the first incidence of a dominant chik outbreak in delhi and prompted us to characterize the delhi virus strains. we have also investigated the evolution of chik spread in india. | 2012 | 22632412 |
| evidence for natural vertical transmission of chikungunya viruses in field populations of aedes aegypti in delhi and haryana states in india-a preliminary report. | aedes aegypti and aedes albopictus are principal vectors for the transmission of chikungunya virus (chikv). india is a hub for both dengue and chikungunya infections and there are several reports of co-infection of dengue and chikungunya virus in the clinical scenario. the present pilot entomological survey was conducted to evaluate vertical transmission of chikv in aedes field populations. aedes immature (larvae and pupae) collection was done in 2012, over a period of six months from selected s ... | 2016 | 27282096 |
| the first dominant co-circulation of both dengue and chikungunya viruses during the post-monsoon period of 2010 in delhi, india. | summaryindependent outbreaks of dengue virus (denv) infection and sporadic cases of chikungunya virus (chikv) have been recorded in the metropolitan city of delhi on several occasions in the past. however, during a recent 2010 arboviral outbreak in delhi many cases turned negative for denv. this prompted us to use duplex reverse transcriptase-polymerase chain reaction (d-rt-pcr) to establish the aetiology of dengue/chikungunya through sequencing of cprm and e1 genes of dengue and chikungunya vir ... | 2011 | 21906409 |
| a study of chikungunya outbreak in delhi. | chikungunya virus, an alphavirus belonging to the togaviridae family, caused large scale outbreaks in several parts of southern, western and eastern india in 2006. we report chikungunya outbreak in delhi in 2010. this study was conducted in the virology laboratory of maulana azad medical college and associated lok nayak hospital, delhi from august 2010 to february 2011. serum samples of 324 patients presenting with fever, arthralgia, myalgia, rash etc. were tested for anti-chikungunya igm antibo ... | 2011 | 23781642 |
| [an imported chikungunya fever case from new delhi, india to ankara, turkey: the first imported case of turkey and review of the literature]. | chikungunya virus (chikv) is an arthropod-borne alphavirus that causes an acute febrile illness, chikungunya fever. chikv virus is geographically distributed in africa, india, and south-east asia. chikungunya fever outbreaks have been reported from india since 2006. the incubation period is 3-7 days, and the disease is characterized by sudden onset of high fever and severe arthralgia. other symptoms can be rash, headache, fatigue, nausea-vomiting, and myalgias. here, we report the first chikungu ... | 2012 | 22399181 |
| evaluation of chikungunya virus infection in children from india during 2009-2010: a cross sectional observational study. | chikungunya virus, a small (about 60-70 nm diameter), spherical, enveloped, positive, single stranded rna virus is transmitted by aedes mosquitoes. after a short period of incubation (3-5 days) symptoms like fever with joint pains and others start appearing. after a gap of 20 years, this virus re-emerged during 2006-2008 in india causing a major outbreak of chikv in india. this study was conducted subsequent to the major outbreak in order to evaluate the proportion of chikungunya virus infection ... | 2016 | 26581026 |
| dengue fever among israeli expatriates in delhi, 2015: implications for dengue incidence in delhi, india. | we present the data of 13 dengue cases diagnosed between 1 august and 15 september 2015 among 240 israeli expatriates residing in delhi. attack rates were similar between adults (6/128, 4.7%) and children (7/112, 6.3%). dengue virus (denv-2) was identified in two and denv-1 in one dengue-seropositive sample. another febrile patient was diagnosed with chikungunya virus infection. the reported incidence of dengue fever among people living in delhi was lower than 0.1% as of september 2015. based on ... | 2016 | 26929156 |
| molecular characterization of dengue and chikungunya virus strains circulating in new delhi, india. | dengue and chikungunya are acute viral infections with overlapping clinical symptoms. both diseases are transmitted by common mosquito vectors resulting in their co-circulation in a region. molecular and serological tests specific for both dengue and chikungunya infections were performed on 87 acute phase blood samples collected from patients with suspected dengue/chikungunya infections in delhi from september to december, 2011. rt-pcr and igm elisa were performed to detect dengue virus (denv) a ... | 2014 | 25346397 |
