Abstract
We identified a new genotype of bufavirus, BuV3, in fecal samples (0.8%) collected to determine the etiology of diarrhea in children in Bhutan. Norovirus GII.6 was detected in 1 sample; no other viral diarrheal pathogens were detected, suggesting BuV3 as a cause of diarrhea. This study investigates genetic diversity of circulating BuVs.
Highlights
In 2012, a novel parvovirus, bufavirus (BuV), was discovered in fecal samples of children with diarrhea in Burkina Faso [1]
Irrespective of severity, hospitalization, or causative agents, the annual morbidity rate for children
The absence of other diarrhea-causing viruses tested for in 2 of the 3 samples containing BuV3 supports a possible role for this parvovirus in diarrhea in infants; direct proof of causation is necessary [11,12]
Summary
One research group, which used PCR to test fecal samples collected in 3 countries, had previously found various proportions of specimens positive for BuV: 4 of 98 (4%) in Burkina Faso, 1 of 63 (1.6%) in Tunisia, and none of 100 in Chile [1]. During February 2010–January 2012, 381 fecal samples (109 in 2010, 185 in 2011, and 87 in 2012) were collected from hospitalized patients or outpatients of Jigme Dorji Wangchuk National Referral Hospital. This hospital mainly serves the population of Thimphu and is the only national reference hospital in the country. The overall proportion of positive samples of BuV in Thimphu was 0.5% (2 samples); 1 (0.9%) was detected
