Survival at room temperature (21-24 degrees C) of herpes simplex virus type 1 (HSV-1) in saliva on plastic doorknobs and chrome-plated tap handles was investigated. There was no loss of infectious virus before 30 min. Between 30 and 60 min there was a 2-log drop in titre, and infectious virus could still be recovered after 2 h, the longest period tested. The marked drop in titre coincided with drying of the saliva. There was no decline in titre of infectious HSV-1 in a humid atmosphere in which the saliva remained liquid. Similar results were seen with HSV-1 in tap water on tap handles.
研究了1型单纯疱疹病毒（HSV-1）在塑料门把和镀铬水龙头把手上唾液中的室温（21 - 24摄氏度）存活情况。30分钟前感染性病毒没有损失。在30至60分钟之间，滴度下降了2个对数，并且在测试的最长时间2小时后仍可回收感染性病毒。滴度的显著下降与唾液干燥同时发生。在唾液保持液态的潮湿环境中，感染性HSV-1的滴度没有下降。水龙头把手上自来水中的HSV-1也出现了类似结果。
