Rotavirus shedding by newborn children.

We studied the shedding of rotavirus by newborn children in the nurseries of a large maternity hospital in Caracas, Venezuela, throughout the year 1982. Sixty-two (57%) of 108 children examined shed the virus within the first few days of life. Four (6%) of the 62 children who shed rotavirus had diarrhea but only one of them required oral rehydration therapy. The rotavirus specimens were identified as subgroup 2 in an ELISA subgrouping assay that employs monoclonal antibodies. Analysis of the RNA extracted from 52 of the samples by electrophoresis revealed a similar migration pattern in all the specimens; their identity was confirmed by crosshybridization analyses which revealed a strong degree of genomic homology among the strains studied.
