“…Indeed, previous studies have shown that diarrhoea in preschool children is mainly due to viral infection. 27 In this study, infection intensity of STHs was assessed as an indirect measure of morbidity. High-intensity infection with A. lumbricoides was frequent (11.2%).…”

a b s t r a c tThe current widespread school-based control of soil-transmitted helminth (STH) infections is also advocated for preschool children. The objective of this study was to assess infection with STHs as well as their determinants in preschool children (<60 months) in southern rural Lao People's Democratic Republic (Lao PDR). A cluster survey was carried out from October to December 2006 in three districts of Savannakhet Province. The prevalence of Ascaris lumbricoides, hookworm and Trichuris trichiura was 27.4% (95% CI 27.0-27.6%), 10.9% (95% CI 10.7-11.0%) and 10.9% (95% CI 10.7-11.1%), respectively. Of the children studied, 28.4% had a monoparasitic infection and 9.3% had a polyparasitic infection. Older children had a higher risk for hookworm infection [odds ratio (OR) = 1.75, 95% CI 1.03-3.01; P = 0.041] and multiple infections (OR = 1.81, 95% CI 1.01-3.20; P = 0.044). Low socioeconomic status was associated with A. lumbricoides (OR = 0.61, 95% CI 0.38-0.98; P = 0.043) and monoparasitic infections (OR = 0.62, 95% CI 0.38-0.99; P = 0.049). In Lao PDR, deworming of preschool children is warranted. Preventive measures should address important risk factors. Health education regarding personal hygiene, appropriate water management and the construction and proper use of latrines are additional essential elements.

Diarrheal diseases are responsible for a significant proportion of mortality and morbidity all around the globe. The contribution of viruses to gastroenteritis incidences in humans is well established. In the present study, we have studied the prevalence of rotavirus, norovirus and enterovirus in Himachal Pradesh, a north Indian state. A total of 287 (111 children and 176 adults) stool samples of gastroenteritis patients were screened for the viruses using RT-PCR method. 34.5 % samples were positive for the viral pathogens of gastroenteritis. Rotavirus was the predominant virus detected in the study with 49.5 and 14.8 % positivity in children and adults, respectively. Enterovirus was present in 5.6 % cases whereas norovirus had least prevalence (1.4 %). Co infection (rotavirus and enterovirus) was witnessed at the prevalence rate of 0.6 %. Among different age groups, the prevalence of studied viruses was highest in the children belonging to the age groups of \5 years. Rotavirus infections were found to be significantly associated with vomiting and trend of higher rates of fever and dehydration was seen in children along with diarrhea. Seasonal distribution shows circulation of diarrheagenic viruses throughout the year. This is the first report of prevalence of various diarrheagenic viruses circulating in this region. The outcome of the study from this cohort provides a baseline data which can be used to design the preventive strategies in the otherwise unexplored state of Himachal Pradesh.

“…Previous reports have demonstrated that RVA and NoV are common causes of nosocomial infections; these reports cite evidence such as aerosol transmission (especially for NoV infection) and the contamination of environmental surfaces and fomites (Wilhelmi et al 2003, Tran et al 2010). Due to the short evaluation period of this study, the seasonality of the viruses could not be inferred; however, the timing of the RVA and NoV infections (p = 0.0149) confirmed previous findings demonstrating increased positivity during the driest months (June-August) of the year in Southwest Brazil (Bittencourt et al 2000, Araújo et al 2002, Carvalho-Costa et al 2006.…”

This retrospective study (April-September 2003) was designed to investigate the roles of the main viruses responsible for cases of acute infantile gastroenteritis in hospitalised children up to two years of age. The viruses were identified in 64.7% (88/136) of the cases and the detection rates of rotavirus A (RVA), norovirus (NoV) and astrovirus were 41.9% (57/136), 30.3% (24/79) and 12.7% (7/55), respectively. RVA and NoV were detected in 20 of the 24 reported nosocomial infection cases. This study identified the first circulation of the genotype NoV GII.21 in Brazil and highlights the need to establish differential diagnoses through active laboratorial surveillance
