The model used for this article included an error. While the text and conclusions are not affected, Table 2 and Equations (1$$k_{\mathit{infectivity}}=0.16030+0.04018\mathrm{ }\left(\frac{\left(T-20.615\right)}{10.585}\right)+0.02176\mathrm{ }\left(\frac{\left(RH-45.235\right)}{28.665}\right)+0.14369\mathrm{ }\left(\frac{\left(S-0.95\right)}{0.95}\right)+\mathrm{ }0.02636\mathrm{ }\left(\frac{\left(T-20.615\right)}{10.585}\right)\left(\frac{\left(S-0.95\right)}{0.95}\right)$$) and (2$$k_{\mathit{infectivity}}=0.17341+0.02218\mathrm{ }\left(\frac{\left(T-20.615\right)}{10.585}\right)+0.03955\mathrm{ }\left(\frac{\left(AH-12.45\right)}{10.82}\right)+0.14488\mathrm{ }\left(\frac{\left(S-0.95\right)}{0.95}\right)+\mathrm{ }0.02624\mathrm{ }\left(\frac{\left(T-20.615\right)}{10.585}\right)\left(\frac{\left(S-0.95\right)}{0.95}\right)$$) are incorrect. Additionally, Table 1 was affected by a rounding error. The corrected versions appear below, and also in the article.

Table 2. Standardized Coefficients for Regression Analyses Peformed with Relative Humidity or Absolute Humidity. Comparison of the standardized coefficients allows the magnitude of the effect of each parameter to be directly compared. For the range of environmental conditions tested, sunlight had the greatest influence on the decay constant for infectivity in either model, followed by temperature and their interaction. Humidity, regardless of whether it was expressed as relative or absolute humidity, had the smallest influence on the decay constant for infectivity. Best fit values are presented with 95% confidence intervals for each coefficient in parentheses underneath.
