BACKGROUND
We recently reported significant association of non-polio enteroviruses (NPEVs) with acute diarrhea in children. Persistent diarrhea (PD) remains a major cause of morbidity and mortality in infants below two years of age in developing countries. Understanding age-dependent frequency and
OBJECTIVE
The purpose of this study was to measure the effect of concurrent diarrheal illness on seroconversion to trivalent oral polio vaccine (OPV).
METHODS
Six- to 16-week-old infants with acute diarrhea and age-matched controls received single doses of OPV at enrollment, 4 weeks after enrollment
We have recently reported significant association of non-polio enteroviruses (NPEVs) with acute and persistent diarrhea (18-21% of total diarrheal cases), and non-diarrheal Increased Frequency of Bowel Movements (IFoBM-ND) (about 29% of the NPEV infections) in children and that the NPEV-associated
A causative agent in approximately 40% of diarrheal cases still remains unidentified. Though many enteroviruses (EVs) are transmitted through fecal-oral route and replicate in the intestinal cells, their association with acute diarrhea has not so far been recognized due to lack of detailed
Oral vaccines for polio (OPV) and rotavirus are less effective in children in the developing world. The reasons for this are not well understood. We tested for risk factors for poor response to OPV in infants from an urban slum of Dhaka, Bangladesh. Diminished serum neutralizing response to OPV, but
Using the adverse events monitoring system of Japan, we observed diarrhea cases in approximately 10% of patients who received oral poliovirus vaccine (OPV). This study was conducted to investigate whether diarrhea among children aged 0 to 1 is caused by OPV or by other factors such contact at the
BACKGROUND
The enteric viruses have high health significance in humans, ranging from poliomyelitis, hepatitis, and gastroenteritis to innocuous infections, and the human enteric viral infection is the one of the most common diseases during early childhood. This study was conducted from July 2010 to
A 56-year-old man with acute paralytic poliomyelitis is described. The illness started with fever and diarrhea after an overseas trip, and an enterovirus other than poliovirus was isolated from the patient's stool. The onset of weakness was rapid and asymmetric, with primary involvement of the lower
The epidemiological, virological, and clinical data of 119 infants less than 30 days of age with enteroviral infection collected from January 1993 to November 1995 by the diagnostic virology laboratories were analyzed retrospectively. Ninety-eight isolates (83%) were obtained in the period of May 1
Oral polio vaccine (OPV) and rotavirus vaccine (RV) exhibit poorer performance in low-income settings compared to high-income settings. Prior studies have suggested an inhibitory effect of concurrent non-polio enterovirus (NPEV) infection, but the impact of other enteric infections has not been
BACKGROUND
Seroprevalence studies provide important data on performance of immunization programs, susceptible groups and populations at-risk of future outbreaks. Identifying risk factors that affect seroconversion of the oral polio vaccine (OPV) will enable the polio eradication initiatives to
A globally-coordinated phase out of all type 2 containing oral polio vaccine (OPV) is planned for April 2016 during which bivalent 1+3 OPV (bOPV) will replace trivalent OPV (tOPV) in routine immunization schedules and campaigns. Diarrhea impairs the immune response to tOPV, but the effect of
BACKGROUND
Egypt provides ideal conditions for poliovirus (PV) transmission (high population density, high contact rates and low sanitation and hygiene in some areas). Despite excellent program performance, wild poliovirus type 1 (PV1) continue to circulate in 2004. To investigate potential causes
During a 24-month period, 561 young children (6 months-2 years of age) hospitalized for acute diarrhea were studied for enteric pathogens. Patients positive for one or more pathogens were 359 (64.0%). Infection with one pathogen was found in 266 (47.4%) patients, whereas multiple infection was
BACKGROUND
X-linked agammaglobulinemia (XLA) is a primary immunodeficiency characterized by failure of B-cell differentiation and hypogammaglobulinemia. In addition to being susceptible to bacterial infections, patients with XLA are also susceptible to enteroviruses. Systemic enterocytopathogenic
