Influence of Relative Humidity on the Survival of Some Airborne Viruses

摘要: Abstract A system for studying the effects of relative humidity (RH) and temperature on biological aerosols, utilizing a modified toroid static aerosol chamber, is described. Studies were conducted at 23 C three RH levels (10, 35, 90%) with four viruses (Newcastle disease virus, infectious bovine rhinotracheitis vesicular stomatitis Escherichia coli B T3 bacteriophage). Virus loss generation was consistently lower 90% than 10 or 35% RH. When stored C, Newcastle virus survived best 10% Infectious E. bacteriophage storage
