Genotyping circulating rotaviruses before and after introduction of rotavirus vaccine is useful for evaluating vaccine-associated changes in genotype distribution. We determined frequency of rotavirus genotypes among 61 rotavirus-positive children hospitalized in Israel during the 2005-06 rotavirus season. Accurate molecular epidemiologic data were recovered from affinity-concentrated rotavirus...

BACKGROUND Rotavirus vaccines were introduced in the United States in 2006. Full-series coverage is lower than for other vaccines, and disease continues to occur. We examined variation in vaccine coverage among provider locations and correlated coverage with the detection of rotavirus in children who sought treatment of severe acute gastroenteritis (AGE). METHODS Vaccine records of children e...

BACKGROUND Rotaviruses are the major cause of diarrhea among the infants and young children all over the world causing over 500,000 deaths and 2.4 million hospitalizations each year. In Nepal Rotavirus infection positivity rates ranges from 17.0 to 39.0% among children less than 5 years. However, little is known about the molecular genotypes of Rotavirus prevailing. The objective of this study ...

OBJECTIVE To evaluate the effectiveness of rotavirus vaccination among young children in Belgium. DESIGN Prospective case-control study. SETTING Random sample of 39 Belgian hospitals, February 2008 to June 2010. PARTICIPANTS 215 children admitted to hospital with rotavirus gastroenteritis confirmed by polymerase chain reaction and 276 age and hospital matched controls. All children were o...

OBJECTIVE This study was conducted to evaluate the prevalence of rotavirus disease and to investigate the genotypes of rotavirus strains causing acute gastroenteritis among children aged <5 years old in Marvdasht, Iran. METHODS One hundred and forty-one children, aged 1 month to 5 years, afflicted with severe diarrhea were enrolled during January 2007 to December 2008. Their stool samples wer...

OBJECTIVE Using case-control methodology, we measured the vaccine effectiveness (VE) of the 2-dose monovalent rotavirus vaccine (RV1) and 3-dose pentavalent rotavirus vaccine (RV5) series given in infancy against rotavirus disease resulting in hospital emergency department or inpatient care. STUDY DESIGN Children were eligible for enrollment if they presented to any 1 of 3 hospitals in Atlant...

Rotavirus is a leading cause of gastrointestinal illness worldwide. Rotavirus transmission occurs fecal-orally, and becomes a critical water quality issue when soil and water resources are contaminated with feces. Transport of pathogens to surface water sources depends on their survival in the soil, especially considering the fact that large amounts of fecal material are often applied to agricu...

Unexpected reports of intussusception after vaccination with the live tetravalent rotavirus vaccine RotaShield resulted in voluntary withdrawal of the vaccine. Intussusception, a condition in which the intestine acutely invaginates upon itself, is the most common cause of intestinal obstruction in children. We report here the development of a mouse model to study rotavirus-induced intussuscepti...

OBJECTIVE To identify rotavirus A and the most prevalent G and P genotypes in children with acute diarrhea, and to the describe the occurrence of rotavirus infection and reinfection. METHODS Group A rotavirus specimens were obtained from fecal samples from children with acute diarrhea in Goiânia, state of Goiás, Brazil from July 2000 to October 2002. Rotavirus A positive children and a contro...

We sensitized sheep erythrocytes (SRBC) with antibodies against human rotavirus strain Wa (SRBC-antiWa) and antibodies against calf rotavirus strain NCDV (SRBC-antiNCDV). These were readily agglutinated in the presence of homologous antigens, i.e., human rotavirus and calf rotavirus. By the hemagglutination of SRBC-antiWa and SRBC-antiNCDV (reverse passive hemagglutination [RPHA]), titration of...
