A Cost–Benefit Analysis of Preparing National Veterinary Services for Transboundary Animal Disease Emergencies

Table 2

Epidemic parameters for three diseases of livestock extracted from global reports to WOAH–WAHIS over the years 2015–2019.

Variable	Region	Species	Outbreak size	Value	Source

			Limited	0.000043	50% of empirical distribution
		Chickens	Major	0.0659	99% of empirical distribution
			Limited	0.00017	50% of empirical distribution
		Cattle	Major	0.131	99% of empirical distribution
			Limited	0.00045	50% of empirical distribution
Case rate within population at risk	Global	Pigs	Major	1	99% of empirical distribution
			Limited	0.174	50% of empirical distribution
		Chickens	Major	1	99% of empirical distribution
			Limited	0.166	50% of empirical distribution
		Cattle	Major	0.564	99% of empirical distribution
			Limited	0.0552	50% of empirical distribution
Mortality rate within cases	Global	Pigs	N/A	0.976	50% of empirical distribution
		Chickens		0.984	50% of empirical distribution
		Cattle		0	50% of empirical distribution
Slaughter rate of extant population at risk	Global	Pigs	N/A	1	50% of empirical distribution
	Global	Chickens		1	50% of empirical distribution
	Global	Cattle		0	50% of empirical distribution

Major and limited outbreaks are defined by the 99th and 50th percentiles of the empirical distribution for each parameter.
