“…In the present study the astrovirus positivity was not significantly more related to one or more symptoms other than diarrhea considering the children from Goiânia city. These results agree with those from a study carried (AG) in relation to the period of year (1994-1996 and 1998-2001) out by López et al (2000) which analyzed children up to ten years from Spain. Studies have shown that astroviruses occur preferentially during the colder months of the year (Phan et al 2004, Galdiero et al 2005) even though other investigations have shown a higher viral incidence during warmest months (Guerrero et al 1998, Naficy et al 2000.…”

This study presents data regarding the circulation of astrovirus in Goiânia-GO and Brasília-DF. These viruses were detected in fecal samples from hospitalized children up to five years old with and without acute gastroenteritis. A total of 1244 fecal samples were collected in two periods, 1994 to 1996 (Brasília) and 1998, and were analyzed for viral RNA using the reverse transcription-polymerase chain reaction (RT-PCR)

“…Previous studies from other European countries reported differing incidences of HAstV infection depending upon the detection method. Using EIA, Lopez et al [2000] reported a HAstV incidence of 5.5% and Schulz et al [2000] an incidence of 1.5% among hospitalized children. Researchers using the more sensitive RT-PCR technique for the detection of HAstV have reported incidence rates varying from 1.5% to 7% among patients with gastroenteritis [Walter et al, 2001;Guix et al, 2002;Kang et al, 2002].…”

Human astroviruses (HAstV) are the causative agents of viral gastroenteritis mainly in children worldwide. This study investigated the epidemiology and genotype diversity of HAstVs detected in children admitted to hospital with gastroenteritis in Hungary. Stool samples were collected from children with diarrhea at the Municipal "Szent László" Hospital, Budapest, Hungary, between January 2002 and December 2002. Of 2,758 samples, 607 were negative for both rotaviruses and bacterial pathogens and were tested for astroviruses using a reverse transcriptase-polymerase chain reaction (RT-PCR) targeting the open reading frame (ORF2), capsid region. Astrovirus was detected in 10 samples (1.6%) by RT-PCR. Astrovirus infection was more frequent among children 49 to 60 months of age. Genotyping of positive samples was performed by type-specific RT-PCR and confirmed by sequence analysis. Phylogenetic analysis was performed using a 203 nucleotide consensus length of the 3'-end of the capsid gene. Type-specific RT-PCR and sequence analysis detected genotypes 1 (50%), 4 (30%), 3 (10%), and 8 (10%) among the children admitted to hospital. Genotype 1 was the predominant genotype, but genotypes 3, 4, and 8 were also present indicating the importance of emerging genotype 8 infections. Two distinct genotype 4 variants were observed during this study. Sequence analysis confirmed type-specific RT-PCR results in the capsid region. This is the first comprehensive report on the occurrence of HAstV infections in Central/Eastern Europe.

“…Astrovirus can be identified in 5%-20% of cases of acute viral gastroenteritis [64][65][66][67]. A study conducted by the Seine Aval program during 4 consecutive years confirmed the presence of astrovirus in the Seine River before the year that the viral gastroenteritis epidemic occurred in Rouen [68,69].…”

This study assessed the epidemiologic characteristics of acute viral gastroenteritis in hospitalized children. A stool sample obtained from each child was analyzed for the presence of astrovirus, calicivirus, rotavirus, adenovirus, enterovirus, and digestive bacteria. Of the 438 stool samples obtained, 138 tested positive for > or =1 pathogen during the winters of 1997-1998 and 1998-1999 (P<.001). Virologic tests revealed rotavirus in 17.3% of samples, calicivirus in 7.3%, astrovirus in 6.8%, adenovirus in 0.7%, and > or =1 virus in 5.4%. Median age was higher for patients with rotavirus gastroenteritis than it was for those with astrovirus or calicivirus gastroenteritis (P=.014). Mean duration of hospitalization was statistically significantly lower for children with rotavirus gastroenteritis (P=.022), despite the more-frequent dehydration observed among children with rotavirus versus those with astrovirus or calicivirus gastroenteritis (P=.007). In contrast, enteral rehydration was more rapidly achieved in patients with gastroenteritis due to rotavirus.
