Table 2.

Estimated transmission rate, recovery rate and R₀ and 95% confidence intervals for the three methods in each of the study herds.

Herd	Herd/rate	Poisson regression	Method 1	Method 2	Mean
1	Transmission rate	0.016 (0.0104–0.0240)	0.015 (0.0018–0.0362)	0.018 (0.0018–0.0495)	0.016
	Recovery rate	0.014 (0.0099–0.0198)	0.011 (0.0014–0.0239)	0.012 (0.0015–0.0324)	0.012
	R0	1.13 (1.02–1.23)	1.34 (1.30–1.38)	1.34 (1.30–1.38)	1.27
2	Transmission rate	0.018 (0.0124–0.0262)	0.019 (0.0088–0.0324)	0.020 (0.0089–0.0361)	0.018
	Recovery rate	0.017 (0.0125–0.0247)	0.016 (0.0080–0.0274)	0.017 (0.0082–0.0305)	0.016
	R0	1.03 (0.94–1.11)	1.14 (1.13–1.16)	1.14 (1.13–1.16)	1.10

The mean estimate of all three methods is shown in the far right column. The units for transmission rate and recovery rate is cases/quarter-day.
