Table 2 Onset of influenza A and B and its association with mean values and declines in temperature (per 1°C) and humidity (0.5 g/m 3 )

From: Decline in temperature and humidity increases the occurrence of influenza in cold climate

Parameter Temperature (°C) OR (95% CI) Absolute humidity (g/m3) OR (95% CI)
Mean 1.10 (1.02 to 1.19) 1.25 (1.05 to 1.49)
Max decline* 1.11 (1.03 to 1.20) 1.58 (1.28 to 1.96)
  1. The odds ratios (95% confidence interval) were calculated per 1°C temperature and per 0.5 g /m3 absolute humidity decreases.
  2. *adjusted for the initial level before the decline.
