Airborne Survival of Rift Valley Fever Virus

Abstract

The aerosol stability characteristics of an Egyptian isolate of Rift/ Valley fever virus (ZH-501 strain) were determined in a static aerosol chamber. Aerosolized particles had a mass median diameter of 4.0 micrometers. At 30, 55, 80% relative humidity (RH) the biological decay rate was 0.9, 4.1, and 10.1% per min, respectively. The decay rate data tested significantly different (P < 0. 001) at each RH. The biological half-life values were 6.9 min at 80% RH, 15.8 min at 55%, and 77.0 min at 30% RH. Comparable decay rates were obtained with a strain (SA-51) isolated in South Africa in 1951.
