“…3). This is distinct from seasonal rotavirus infections in temperate climates [Cook et al, 1990], but similar to previous studies reporting a lack of seasonality with a deviation of infections towards warmer months in children and adults from tropical countries [Maldonado and Yolken, 1990;Carraro et al, 2008].

A total of 1,591 fecal specimens were collected in 1993-1996 and 2004-2007 from adolescents and adults with acute gastroenteritis in Pune, India for detection and characterization of rotavirus. At the two time points, group A rotavirus was detected in 8.6% and 16.2% of the adolescents and 5.2% and 17.2% of the adults, respectively. Reverse transcription-PCR with consensus primers followed by multiplex genotyping PCR detected common strains G1P[8], G2P[4], G3P[8], and G4P[8] in a total of 53.1% of the samples from 1993 to 1996, while the only prevalent strain identified in 2004-2007 was G2P[4] (23.5% of total). Uncommon rotavirus strains (G1P[4], G2P[8] G9P[6]/P[4]) increased from 7.8% (1993-1996) to 41.2% (2004-2007), while the prevalence of mixed rotavirus infections was high (39%/35%) at both time points. Mixed infections detected by multiplex PCR were confirmed by sequencing two or more individual genotype-specific PCR products of the VP7 and VP4 genes from the same sample. Phylogenetic analysis of the sequences showed circulation of a heterogeneous rotavirus strain population comprising genotypes G1 (lineages I and IIb), G2 (lineages I and IIb), G4 (lineage Ia), P[4] (lineages P[4]-5 and P[4]-1), P[8] (lineages P[8]-II and P[8]-III), and P[6] (M37-like lineage). The VP6 gene sequences of the nontypeable strains were most homologous to animal strains. This study documents the molecular epidemiology of rotavirus strains in adolescents and adults in India, and suggests that it may be important to monitor these strains over time for the potential impact on rotavirus vaccines under development for use in the Indian population.

“…In the present study, the results of RT-PCR revealed no correlation with different parameters included: age, sex, residence, type of feeding, and source of drinking water RV is the most causative agent of diarrhea worldwide (31). RV is transmitted by the mouth through the consumption of water and food contaminated with the virus, and contributes to many of the factors in the transmission of RV, especially in developing countries, as poor health awareness and attention to personal and public hygiene , pollution of water and foods intended for human consumption (29), where RV is responsible for more than 870 thousand new cases and deaths per year among children under five years of age in developing countries (43).…”

The present study was conducted for the period from 1/6/2016 to 20/1/2017 in Baquba city. The study aimed to detection of rotavirus in stool specimens of children fewer than five age and also explore the effects of certain demographic factors on the detection rates by revers transcriptase-polymerase chain reaction. The study included 49 patients with acute diarrhea, 32 were male and 17 were female. The age range was two months to 5 years. Demographic information on the patients regarding age, sex, residence, type of feeding and source of drinking water were collected from their parents. Stool specimens were collected from each patients and. Detection of rotavirus in stool specimens was done by conventional reverse transcriptase polymerase chain reaction (RT-PCR). The results of present study showed that the overall infection rate by rotavirus among patients with acute diarrhea by RT-PCR tests was 93.88%. The highest infection rate was recorded among those >10-≤15 months of age. None of the results showed significantly difference between female and male, PCR (88% vs 96.87%). Likewise, there was insignificantly difference between urban and rural residence, PCR (95.65% vs 92.30%). The results revealed insignificantly higher infection rate among patients (those below 2 years) feed mixing (91.66%) and bottled (100%) compared to that breast feeding (77.77%) by RT-PCR. The rotavirus infection rate was insignificantly higher among patients consuming municipal water for drinking (97.22%) compared to those consuming bottled water (84.61%) by the RT-PCR. The study concluded that rotavirus was detected in high rates among children less than 5 years old with acute diarrhea in Baquba city, particularly those less than 2 year old.

“…In our study, the prevalence of RV was 64.9%. This prevalence is higher than what has been previously reported in other Latin American countries, including Brazil (20%), Colombia (29.2%), and Chile (50% hospitalized patients and 35% outpatients) [26][27][28]. The high number of hospitalizations in children positive to RV in the present study might be associated to dehydration due to intensive vomiting.…”

Infectious gastroenteritis is one of the most common illnesses among children and is caused by many etiological agents; however, viruses are responsible for 50 to 75% of all cases. A laboratory-based study was carried out from 2005-2006 aiming to describe epidemiological aspects of rotavirus (RV), astrovirus, and adenovirus associated with gastroenteritis in Mexican children. Children younger than 5 years with acute diarrhea from four clinics and eight daycare centers were studied. The presence of RV was determined using polyacrylamide gel electrophoresis (PAGE) with silver staining. Negative samples were further tested for RV, adenovirus, and astrovirus using immunoassays. A total of 727 children were studied. The RV prevalence by PAGE was 56.8% (413/727). Out of 314 samples that were PAGE negative, 18.1% (57/314) were positive for any virus; the prevalence for the specific viruses was 9.5% (30/314); for RV, 4.4% (14/314); for astrovirus; 3.8% (12/314); for adenovirus, and 0.3% (1/314) with RV and astrovirus mixed infection. Viruses are responsible of more than 60% of acute diarrhea diseases among Mexican children.
