| Abstract |
The aims of this study were to monitor human astrovirus (HAstV) infections in patients presenting with acute gastroenteritis in Brazil and to determine the HAstV genotypes of these viruses. From May 2010 to July 2012, a total of 140 samples that were negative for both rotaviruses and noroviruses were randomly selected and tested for the presence of HAstV using an RT-PCR assay specific for the ORF2 region. Viral genotypes were identified and genetic diversity was investigated by sequencing. HAstV infection was detected in 2.9% of samples (4/140). The viruses in three samples were shown by phylogenetic analysis to belong to HAstV-4 lineage "c", clustering together with strains detected in Europe and the Middle East. The virus in one sample was genotyped as HAstV-1 lineage "a", clustering with strains from Uruguay, Brazil and Russia. Our findings provide further evidence for a global distribution of HAstV-1a and suggest a possible emergent importance of the HAstV-4c lineage in this country. The present study does not suggest that HAstVs currently have a major epidemiological impact, even after the introduction of a rotavirus vaccine in 2006. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 February 2018.
All research outputs
#17,927,741
of 23,018,998 outputs
Outputs from Archives of Virology
#2,886
of 4,208 outputs
Outputs of similar age
#309,708
of 440,328 outputs
Outputs of similar age from Archives of Virology
#45
of 88 outputs
Altmetric has tracked 23,018,998 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,208 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 27th percentile – i.e., 27% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 440,328 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 88 others from the same source and published within six weeks on either side of this one. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
