	abstract = {The survival of airborne human coronavirus 229E (HCV/229E) was studied under different conditions of temperature (20 +/- 1 degree C and 6 +/- 1 degree C) and low (30 +/- 5\%), medium (50 +/- 5\%) or high (80 +/- 5\%) relative humidities (RH). At 20 +/- 1 degree C, aerosolized HCV/229E was found to survive best at 50\% RH with a half-life of 67.33 +/- 8.24 h while at 30\% RH the virus half-life was 26.76 +/- 6.21 h. At 50\% RH nearly 20\% infectious virus was still detectable at 6 days. High RH at 20 +/- 1 degree C, on the other hand, was found to be the least favourable to the survival of aerosolized virus and under these conditions the virus half-life was only about 3 h; no virus could be detected after 24 h in aerosol. At 6 +/- 1 degree C, in either 50\% or 30\% RH conditions, the survival of HCV/229E was significantly enhanced, with the decay pattern essentially similar to that seen at 20 +/- 1 degree C. At low temperature and high RH (80\%), however, the survival pattern was completely reversed, with the HCV/229E half-life increasing to 86.01 +/- 5.28 h, nearly 30 times that found at 20 +/- 1 degree C and high RH. Although optimal survival at 6 degree C still occurred at 50\% RH, the pronounced stabilizing effect of low temperature on the survival of HCV/229E at high RH indicates that the role of the environment on the survival of viruses in air may be more complex and significant than previously thought.},
