Table 2 Seasonality time-dependent reproduction number in the Northern hemisphere

From: Seasonal transmission potential and activity peaks of the new influenza A(H1N1): a Monte Carlo likelihood analysis based on human mobility

Month R(t) in Northern hemisphere
May 1.19 to 1.49
June 1.07 to 1.33
July 1.05 to 1.24
August 1.07 to 1.33
September 1.19 to 1.49
  1. The values of R(t) for the Northern hemisphere correspond to the rescaling of the maximum likelihood value of R 0 in Mexico and in the Tropical regions (R 0 = 1.75) and the best values for the seasonality rescaling factor, 0.6 < αmin < 0.7. The parameter αmin indicates the minimum value of the seasonal rescaling of R 0 induced by the sinusoidal forcing in the Northern hemisphere [17].
