Diagnosis and Clinical Manifestations of Diarrheal Virus Infections in Maizuru Area from 1991 to 1994

Abstract

Rotavirus (44.7%), adenovirus (5.6%), small round structured viruses such as astrovirus (9.8%) and Norwalk like virus (6.9%) were detected by latex agglutination and reverse transcription polymerase chain reaction amplification from 378 stool samples in an outpatient clinic of Pediatrics in Maizuru area from 1991 to 1994. 70.0% were found from 6 months to 2 years old and 91.0% were detected from January to April. Serotype 1 astrovirus and group 2 Norwalk like virus were mainly found in all serotypes in each virus. Diarrhea, vomiting, nausea, fever, cough and rhinorrhea, and severity of diseases were examined in each case. Fever is significantly found in patients with rotavirus. Sporadic cases with small round structured viruses were recognized in the outpatient clinic of pediatrics.

Astrovirus gastroenteritis in hospitalized children of less than 5 years of age in Taiwan, 2009

“…The previous reports from Japan 28 Eight serotypes of human astroviruses have been recognized, denoted HAstV-1 to HAstV-8. All eight HAstV serotypes or genotypes have been detected throughout the world.…”

Epidemiology of gastroenteritis viruses in Japan: Prevalence, seasonality, and outbreak

“…Soon after the discovery, human astroviruses were reported from acute gastroenteritis pediatric patients globally and several countries in Asia [Malasao et al, ; Matsumoto et al, ; Mitui et al, ; Wang et al, ]. Most studies of human astrovirus in Japan had focused on the detection of classic human astrovirus which accounted for about 0.7–15.9% of infection in children with diarrhea [Ueda et al, ; Araki et al, ; Sakamoto et al, ; Akihara et al, ; Phan et al, ; Nakanishi et al, ; Chan‐it et al, ; Mori et al, ; Thongprachum et al, ]. The first outbreak of human astrovirus in kindergarten had been reported since 1982.…”

Identification of gastroenteric viruses by electron microscopy using higher order spectral features

“…These are Rotavirus, Astrovirus, Adenovirus and Calicivirus (Kapikian, 1996;Glass et al, 2001). Many studies have been conducted to determine which gastroenteric viruses are more prevalent with respect to geography, sex, seasonal pattern and age distribution (Diamanti et al, 1996;Ueda et al, 1996;Haiping et al, 1999;Bereciartu et al, 2002;Subekti et al, 2002;Oh et al, 2003). Research shows that Rotavirus is responsible for the majority of these deaths and 20-52% of all acute gastroenteric episodes (Cunliffe et al, 2002a;Hart, 2003;Rivest et al, 2004).…”
