Novel human astroviruses: challenges for developing countries

Abstract

Astroviruses have been gaining widespread importance over the past few decades owing to their detection through advanced molecular techniques. The association of astrovirus-associated enteric infections have been reported from various settings among different age groups. The tremendous efforts of scientists from different countries to detect and characterize these star-like viruses in the course of surveillance has shown the emergence of novel astroviruses from varied host species, necessitating changes in the classification to update their taxonomy. The public health importance of these viruses implies new control measures are essential to reduce disease burden in developing countries.
