The study was conducted to investigate the molecular epidemiology of noroviruses (NoVs) from western India. A total of 830 fecal specimens were collected during July 2005-June 2007 from children, < or =7 years of age suffering from acute gastroenteritis in Pune, Nagpur, and Aurangabad cities. All the specimens were subjected to RT-PCR, sequencing and(More)
BACKGROUND/AIMS Hepatitis A and E viruses (HAV, HEV) are transmitted enterically and are highly endemic in India. This study aims to evaluate prevalence of these and TT virus (TTV) in the sewage. METHODS Influent and effluent samples from a sewage treatment plant from Pune, India were collected twice a week for 1 year and subjected to nested polymerase(More)
BACKGROUND Current, nationally representative data on rotavirus disease burden and rotavirus strains in India are needed to understand the potential health benefits of rotavirus vaccination. METHODS The Indian Rotavirus Strain Surveillance Network was established with 4 laboratories and 10 hospitals in 7 different regions of India. At each hospital,(More)
Hand, foot and mouth disease (HFMD), a common contagious disease that usually affects children, can be caused by enteroviruses. Coxsackievirus A16 (CV-A16) and enterovirus 71(EV-71) are the major aetiological agents of HFMD. Other EV serotypes, CV-A4-7, CV-A9-10, CV-B1-3, CV-B5, E-4 and E-19, have also been found associated with both sporadic infections and(More)
A five-year (2004-2008) study was conducted on patients with acute gastroenteritis from different cities of Maharashtra, western India to detect and characterize astrovirus infections. A total of 1340 fecal specimens were collected from sporadic cases that included 1240 children (<or=8 years) and 100 adults (18-70 years) from Pune, Aurangabad and Nagpur(More)
BACKGROUND In India the role of noroviruses in causing gastroenteritis is not well defined. OBJECTIVE To determine the norovirus prevalence in sporadic cases of acute gastroenteritis in western India. STUDY DESIGN A total of 236 fecal specimens consisting 192 specimens from hospitalized and 44 from OPD (outpatient department) children < or = 5 years of(More)
The epidemiology of hepatitis A virus (HAV) and hepatitis E virus (HEV) was assessed among age-stratified urban high socioeconomic, lower middle socioeconomic status and rural populations from western India in 1998. When compared with previous surveys, a clear shift from high to intermediate endemicity of HAV was evident only for higher socioeconomic(More)
We used published and unpublished studies and national statistics to estimate the number of deaths, hospitalizations, and outpatient visits due to rotavirus diarrhoea and the associated national economic burden of disease in India. Annually in India, rotavirus diarrhoea causes an estimated 122,000-153,000 deaths, 457,000-884,000 hospitalizations, and 2(More)
An outbreak of viral encephalitis occurred in northern India in 2006. Attempts to identify an etiologic agent in cerebrospinal fluid by using reverse transcription-PCR showed positivity to enterovirus (EV) in 66 (21.6%) of 306 patients. Sequencing and phylogenetic analyses of PCR products from 59 (89.3%) of 66 specimens showed similarity with EV-89 and(More)
A total of 78 fecal specimens were collected from both apparently healthy (n=71) and diarrheic (n=7) cattle from an organized farm in Pune, western India in December 2007-January 2008. Three specimens tested positive for group A rotavirus (RV) by antigen capture ELISA were subjected to RT-PCR for amplification of entire coding regions of three structural(More)
