Reduction in transmission. The effect on the eradication threshold condition T₀ of reducing the transmission rate over a twenty year period to two fifths of the current value by decreasing the infection rate from 2010 levels to two fifths its current value, in 2030. A. Assuming population demographics remain unchanged. B. Assuming 3% population growth per year. Population increases over time result in the inability to eradicate the disease using this technique.
