Since its re-emergence in 2005, chikungunya virus (CHIKV) transmission has been documented most Indian states. Information is scarce regarding the seroprevalence of CHIKV India. We aimed to estimate age-specific seroprevalence, force infection (FOI), and proportion population susceptible infection.We did a nationally representative, cross-sectional serosurvey, which we randomly selected individuals three age groups (5-8, 9-17, 18-45 years), covering 240 clusters from 60 districts 15 states...
The effect of insecticide-treated mosquito nets (ITMNs) on Japanese Encephalitis (JE) virus seroconversion in pigs and humans was studied Assam, Northeast India. A sharp reduction rate human pig found treated localities after intervention. marked achieved (risk ratio [RR] = 0.28, 95% confidence interval [CI] 0.16–0.49) (RR 0.21, CI 0.11–0.40) the Kollolua locality where ITMNs were used both compared with other two area, Athabari Rajmai, covering only either or pigs. Monitoring population...
Neuropathic pain of various etiology is the most commonly reported at primary clinics by patients. Patients experience moderate to severe chronic pain, impacting quality life (QoL) and mood. The mainstay treatment includes gabapentinoid-based reduce severity improve QoL for In a retrospective cross-sectional survey in India, drug usability neuropathic was studied. This included data collection from neurological across India that considered patient demographics, comorbidities, type...
A temporal relationship of Japanese encephalitis virus (JEV) transmission in pigs, mosquitoes and humans revealed that sentinel pig seroconversions were significantly associated with human cases 4 weeks before (P = 0·04) their occurrence, highly correlated during the same time 2 case occurrence < 0·001), remained up to after 0·01). JEV was detected month pigs mosquitoes, peaks seroconversion preceded by 1-2 months infection vectors. Kaplan-Meier analysis indicated detection JEV-positive...
Dengue has been reported from plains as well hilly regions of India including some parts Northeast India. In July-August 2012, outbreak fever with unknown origin (FUO) indicative was in Pasighat, East Siang district Arunachal Pradesh (AP) state. Serum samples ( n = 164) collected patients Health Training and Research Centre General Hospital, were tested for NS1 antigen IgM antibodies. NS1-positive analyzed by RT-PCR assay entomological surveys carried out. The majority suspected cases...
West Nile virus (WNV) is a zoonotic flavivirus maintained in mosquito-bird transmission cycle. Although humans are accidental hosts, fatal outcomes following WNV infection have been reported from India. Studies identified as an important etiological agent causing acute encephalitis syndrome Assam, Northeast While circulation of evident, the role vectors and avian hosts involved remains unclear. In this study we local mosquito species for evidence along with seroconversion among sentinel...
A convenient ultrasound assisted synthesis of new anti-bacterial N-benzylidene-N'-(1-methyl-2, 2-dioxo-2,3-dihydro-1H-2λ 6 -benzo[c][1,2]thiazin-4-ylidene)hydrazines from methyl anthranilate is reported.Methyl was reacted with methane sulfonyl chloride, followed by N-alkylation and subsequent base catalyzed cyclization.Hydrazinolysis the cyclized products their mediated condensations different benzaldehydes yielded title compounds.Some these compounds showed good activity against Pseudomonas...
The incidence of fever cases unknown origin has increased in Northeastern Region India recent years.We conducted passive surveillance and performed laboratory testing on suspected for the presence dengue infection during 2009-2011.We estimated by applying age, sex season adjusted positivity.We identified 430 which 143 (33.3%) were found to be laboratory-confirmed cases.Dengue transmission was occur post-monsoon (September-December).We evaluated differences clinical features hematologic...
Scrub typhus, caused by the intracellular bacteria Orientia tsutsugamushi is widely distributed in Southeast Asian countries with antigenically divergent strains reported across Asia–Pacific belt. The present study was conducted to characterize circulating of prevailing two Northeastern states India—the gateway most countries. A total 278 (98 clinical and 180 field collected) scrub typhus positive blood samples collected from December 2014 2016 were subjected for amplification partial 56...
We estimate the effectiveness of Japanese encephalitis (JE) SA 14-14-2 live-attenuated vaccination single dose campaign among children aged 1-15 years in India during 2006-07.Acute syndrome (AES) cases hospitalized following campaigns 2006-08 were investigated retrospectively. The laboratory-confirmed JE detected from surveillance laboratories based on anti-JE IgM antibody by ELISA or viral RNA detection RT-PCR sera cerebrospinal fluid. Consent was sought parents guardians. Four community...
IntroductionIndia introduced a hepatitis-B (HB) vaccine in the Universal Immunization Program 2002–2003 on pilot basis, expanded to ten states 2007–2008 (phase-1), and entire country 2011–2012 (phase-2). We tested sera from nationally representative serosurvey conducted duing 2017, estimate seroprevalence of different markers HB infection among children aged 5–17 years India assess impact vaccination.MethodsWe 8273 for estimated weighted age-group specific who were chronically infected...
During June-September 2008, an illness characterized by fever, headache and joint pain was reported in Assam state, northeast India. It presented characteristic features resembling chikungunya or dengue virus infection based on clinical symptoms. Dengue IgM antibody detected 10.0% (28/280) 3.6% (10/280) patients respectively. The positive did not travel to from any endemic region confirming indigenous transmission. Persistent arthralgia hearing loss has been observed a recovered patient....
