Eh. Elbasha et al., Costs and benefits of a subtype-specific surveillance system for identifying Escherichia coli of O157 : H7 outbreaks, EM INFECT D, 6(3), 2000, pp. 293-297
We assessed the societal costs and benefits of a subtype-specific surveilla
nce system for identifying outbreak-associated Escherichia coli O157. H7 in
fections. Using data from Colorado, we estimated that if it averted five ca
ses annually, the system would recover all its costs.
