In January 2011, human cases with hemorrhagic manifestations in the hospital staff were reported from a tertiary care Ahmadabad, India. This paper reports detailed epidemiological investigation of nosocomial outbreak affected area Gujarat, India.Samples 3 suspected cases, 83 contacts, Hyalomma ticks and livestock screened for Crimean-Congo fever (CCHF) virus by qRT-PCR which samples two medical professionals (case C E) husband index case D) positive CCHFV. The sensitivity specificity...
The global pandemic caused by SARS-CoV-2 virus has challenged public health system worldwide due to the unavailability of approved preventive and therapeutic options. Identification neutralizing antibodies (NAb) understanding their role is important. However, data on kinetics NAb response among COVID-19 patients are unclear. To understand in patients, we compared findings microneutralization test (MNT) plaque reduction neutralization (PRNT) for SARS-CoV-2. Further, was assessed.A total 343...
Background & objectives: Since the beginning of year 2020, pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) impacted humankind adversely in almost all spheres life. The virus belongs to genus Betacoronavirus family Coronaviridae . SARS-CoV-2 causes disease known as 2019 (COVID-19) with mild-to-severe illness. currently available diagnostic tools for diagnosis COVID-19 are mainly based on molecular assays. Real-time reverse transcription-polymerase chain...
Abstract Background In India, Pune was one of the badly affected cities during influenza A (H1N1) 2009 pandemic. We undertook serosurveys among risk groups and general population to determine extent pandemic virus infections. Methods Pre-pandemic sera from archives, collected January 2005 March 2009, were assayed for determination baseline seropositivity. Serosurveys undertaken such as hospital staff, practitioners, school children staff between 15 th August 11 December 2009. addition,...
Kyasanur forest disease (KFD) outbreak was confirmed in Dodamarg Taluka, Sindhudurga district (Maharashtra) India during the year 2016. The rise suspected KFD cases reported January 2016, peaked March, and then declined gradually from April thoroughly investigated considering different socio-clinical parameters.Total, 488 were using specific real-time RT-PCR anti-KFDV IgM enzyme-linked immunosorbent assay (ELISA). Sero-epidemiological survey carried out affected area IgG ELISA.Among cases,...
Crimean Congo Hemorrhagic Fever (CCHF) is a highly infectious zoonotic disease of humans transmitted by Hyalomma ticks. Earlier studies have shown CCHF seroprevalence in livestock throughout India, yet sporadic outbreaks been recorded mostly from the Gujarat state India since 2011. Occupational vulnerability to for animal handlers, veterinarians, abattoir workers, and healthcare workers has documented. The current study was planned determine with an intention identify high -risk population...
Real-time reverse transcription polymerase chain reaction (rRT-PCR) is one of the most accurate and extensively used laboratory procedures for diagnosing COVID-19. This molecular test has high diagnostic accuracy (sensitivity specificity) considered as gold standard COVID-19 diagnosis. During surge in India, rRT-PCR service was encouraged supported by government India through existing healthcare setup at various levels facilities. The primary purpose this research to determine per-unit cost...
Crimean-Congo hemorrhagic fever virus (CCHFV) etiology was detected in a family cluster (nine cases, including two deaths) the village of Karyana, Amreli District, and also fatal case Undra, Patan Gujarat State, India. Anti-CCHFV IgG antibodies were domestic animals from Karyana adjoining villages. Hyalomma ticks households found to be positive for CCHF viral RNA. This confirms emergence CCHFV new areas wide spread this disease State.
Unusual rise of acute encephalitis syndrome cases (AES) were reported in July 2014 the northern region West Bengal, India. Investigations carried out to characterize outbreak and identify associated virus etiology. This observational study is based on 398 line listed AES cases, mostly (70.8%, 282/398) adults, with case fatality ratio 28.9% (115/398). Japanese infection was detected 134 (49.4%) among 271 tested most them (79.1%, 106/134) adults. The reports a large genotype III adults J. Med....
Abstract The pandemic of COVID‐19 has caused enormous fatalities worldwide. Serological assays are important for detection asymptomatic or mild cases COVID‐19, and sero‐prevalence vaccine efficacy studies. Here, we evaluated compared the performance seven commercially available enzyme‐linked immunosorbent assay (ELISA)s anti‐severe acute respiratory syndrome corona virus 2 (SARS‐CoV‐2) immunoglobulin G (IgG). ELISAs were with a characterized panel 100 serum samples from qRT‐PCR confirmed...
Monitoring the antibody responses to SARS-CoV-2 infection and its correlation clinical spectrum of disease is critical in understanding progression protection against re-infection. We assessed nucleocapsid (N) receptor-binding-domain spike (SRBD) protein specific IgG neutralizing (NAb) COVID-19 patients up 8 months with diverse spectrum.During first wave pandemic, from 284 patients, 608 samples were collected post infection. The categorized as asymptomatic, symptomatic severe. N SRBD NAb...
SUMMARY An outbreak of influenza A(H1N1)pdm09 was detected during the ongoing community-based surveillance influenza-like illness (ILI). Among reported 119 cases (59 in year 2012 and 60 2015) summer months, common clinical features were fever (100%), cough (90·7%), sore throat (85·7%), nasal discharge (48·7%), headache (55·5%), fatigue (18·5%), breathlessness (3·4%), ear (1·7%). Rise ILI negatively correlated with seasonal factors such as relative humidity (Karl Pearson's correlation...
Background: A massive outbreak of dengue-like illness was reported from Pune district Maharashtra, India during May-June 2022. Isolation and characterization the etiological agent at genomic level for possible mutations that led to higher transmissibility is topic study. Methods: Entomological investigations were carried out by ICMR-National Institute Virology (Pune, India); Aedes aegypti mosquitoes collected processed virus detection molecular techniques. Positive mosquito pools isolation...
