Abstract
The influence of relative humidity on the airborne survival of simian virus 40 (SV40) was studied by allowing virus aerosols to age in rotating drums at 21 or 32 C and at a relative humidity (RH) value ranging from 22 to 88%. Airborne SV40 virus was stable at every RH tested at 21 C, but aerosols maintained at 32 C were inactivated within 60 min at mid-range RH values. The unusual stability at 21 C over a broad RH range indicates that potentially biohazardous situations may occur under laboratory conditions if this virus becomes accidentally airborne.
摘要
通过让病毒气溶胶在21或32℃的旋转鼓中老化，并在22%至88%的相对湿度（RH）值下，研究了相对湿度对猿猴病毒40（SV40）空气传播存活的影响。在21℃测试的每个相对湿度下，空气传播的SV40病毒都很稳定，但在32℃保持的气溶胶在中等相对湿度值下60分钟内就会失活。在较宽的相对湿度范围内21℃时的异常稳定性表明，如果这种病毒意外地空气传播，在实验室条件下可能会出现潜在的生物危害情况。
