Enterovirus 71 (EV71) (genus Enterovirus, family Picornaviridae), a common cause of hand, foot, and mouth disease (HFMD), may also cause severe neurological diseases, such as encephalitis and poliomyelitis-like paralysis. To examine the genetic diversity and rate of evolution of EV71, we have determined and analyzed complete VP1 sequences (891 nucleotides)(More)
From April through June 1997, 29 previously healthy children aged <6 years (median, 1.5 years) in Sarawak, Malaysia, died of rapidly progressive cardiorespiratory failure during an outbreak of hand, foot, and mouth disease caused primarily by enterovirus 71 (EV71). The case children were hospitalized after a short illness (median duration, 2 days) that(More)
In February 2006, a live, oral, human-bovine reassortant rotavirus vaccine (RotaTeq) was licensed for use among U.S. infants. The Advisory Committee on Immunization Practices recommends routine vaccination of U.S. infants with 3 doses of this rotavirus vaccine administered orally at ages 2, 4, and 6 months. The first dose should be administered between ages(More)
Timely investigation of children with acute flaccid paralysis, with collection of stool specimens for virus isolation, is the primary strategy used to detect wild poliovirus circulation. To determine the optimal timing of stool specimen collection, studies of wild and vaccine poliovirus excretion published between 1935 and 1995 were reviewed. Data were(More)
OBJECTIVES Our objective was to determine the following among US pediatricians: (1) perceptions regarding burden of rotavirus disease and need for a vaccine; (2) intentions for recommending a newly licensed rotavirus vaccine; (3) perceived barriers to implementation; and (4) factors associated with plans for vaccine adoption. PATIENTS AND METHODS A(More)
Since first described in 1974, enterovirus 71 infections have been associated with severe neurologic disease, and widespread infection was suspected in 1987. To investigate enterovirus 71 activity further, data were reviewed for isolations reported nationally during 1977-1991, virology laboratories were contacted regarding isolations during 1985-1989, and(More)
The true incidence of myocarditis in children is difficult to estimate because many mild cases go undetected. This study describes an unusual cluster of myocarditis cases that occurred in young children living in the greater Baltimore area between May and October 1997. A search of multiple comprehensive databases and interviews with area pediatric(More)
BACKGROUND Oral poliovirus vaccine (OPV) has not been used in the United States since 2000. Type 1 vaccine-derived poliovirus (VDPV) was identified in September 2005, from an unvaccinated Amish infant hospitalized in Minnesota with severe combined immunodeficiency. An investigation was conducted to determine the source of the virus and its means of(More)
In July 1992, 13 parents with children attending a child care center (CCC) developed aseptic meningitis (AM) due to echovirus 30 (E30). To determine the extent of illness and risk factors for transmission, survey and blood specimens were collected from CCC families and teachers and from adult and pediatric controls. Infection was defined as the presence of(More)
OBJECTIVES Routine vaccination of US infants against rotavirus was implemented in 2006, prompting the Centers for Disease Control and Prevention New Vaccine Surveillance Network to begin population-based acute gastroenteritis surveillance among US children<3 years of age. This surveillance system establishes baseline estimates of rotavirus disease burden(More)
