The survival of pseudorabies virus in an aerosol was studied under different environmental conditions of temperature and relative humidity. Pseudorabies virus decayed logarithmically with mean half-lives of 17.4 (85% relative humidity, 22 C), 18.8 (25% relative humidity, 22 C), 27.3 (85% relative humidity, 4 C), 36.1 (55% relative humidity, 22 C), and 43.6 (55% relative humidity, 4 C) minutes. Virus survival was significantly improved in environments at 55% relative humidity, compared with those at 85% relative humidity (P = 0.017). Rates of survival were improved in environment at 4 C in comparison with those at 22 C. Results suggest that, under the best conditions of this study, the infectivity of pseudorabies virus in an aerosol decreases by 50% in less than 1 hour.
在不同温度和相对湿度的环境条件下，研究了伪狂犬病病毒在气溶胶中的存活情况。伪狂犬病病毒呈对数衰减，平均半衰期分别为17.4分钟（相对湿度85%，22℃）、18.8分钟（相对湿度25%，22℃）、27.3分钟（相对湿度85%，4℃）、36.1分钟（相对湿度55%，22℃）和43.6分钟（相对湿度55%，4℃）。与相对湿度85%的环境相比，在相对湿度55%的环境中病毒存活情况显著改善（P = 0.017）。与22℃环境相比，4℃环境中的病毒存活速率有所提高。结果表明，在本研究的最佳条件下，气溶胶中伪狂犬病病毒的传染性在不到1小时内降低50%。
