The stools of 37 newborn babies born in hospital were examined for the presence of virus. An extract of every stool passed by each baby was examined in the electron microscopy and inoculated into cell cultures. The babies were delivered in four separate maternity units (A-D). All the babies from unit A and C(9 babies) were found to be excreting rotavirus though none showed any evidence of diarrhoea. Two of the babies also excreted astrovirus. Subsequently unit A was closed for cleaning and, on reopening with more restrictions on visitors, a further 19 babies were examined. No virus was found in any of their stools, nor was virus observed in the stools of babies from units B and D, where visiting was also more restricted. Visiting restrictions in these units excluded older siblings of the babies. No virus was cultured from any stools in this study.
对在医院出生的37名新生儿的粪便进行了病毒检测。对每个婴儿排出的每一份粪便提取物进行电子显微镜检查，并接种到细胞培养物中。这些婴儿在四个不同的产科病房（A - D）出生。发现A病房和C病房的所有婴儿（共9名）都在排出轮状病毒，尽管没有任何婴儿表现出腹泻的迹象。其中两名婴儿还排出了星状病毒。随后A病房关闭进行清洁，重新开放并对访客实施更多限制后，又对另外19名婴儿进行了检查。在他们的任何粪便中都未发现病毒，在B病房和D病房婴儿的粪便中也未观察到病毒，这两个病房的访客限制也更多。这些病房的访客限制排除了婴儿的哥哥姐姐。在本研究中，任何粪便中都未培养出病毒。
