Excretion of virus in the throat, urine, and conjunctiva of smallpox patients was studied daily for 2-3 weeks after the onset of fever. The virus titre in the throat and urine of haemorrhagic and confluent cases was higher than in discrete cases. The duration of virus excretion was also greater in confluent cases than in discrete cases. Conjunctival swabs from all 12 smallpox patients with conjunctivitis were positive for virus. The duration and titre of virus excretion in the throat, urine, and conjunctiva of patients were not related to their age or sex and did not depend on whether or not they had received a primary vaccination.
在天花患者发热开始后的2至3周内,每天对其咽喉、尿液和结膜中的病毒排泄情况进行研究。出血性和融合性病例的咽喉和尿液中的病毒滴度高于离散性病例。融合性病例的病毒排泄持续时间也比离散性病例更长。所有12例患有结膜炎的天花患者的结膜拭子病毒检测均呈阳性。患者咽喉、尿液和结膜中病毒排泄的持续时间和滴度与他们的年龄或性别无关,也不取决于他们是否接受过初次疫苗接种。
