Para una familia argentina, entender qué circula en los hospitales vecinos sirve como alerta sin que haga falta entrar en pánico.

AGE is characterized by symptoms including diarrhea, vomiting, abdominal pain, and fever and may require hospitalization in severe cases. Methods: A total of 131 stool samples collected from children hospitalized with AGE at a hospital in Salvador, Bahia, were analyzed. HBoV was detected using nested polymerase chain reaction (nested PCR). Positive samples were sequenced and inoculated into Vero cell cultures, followed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and Western blotting.
