Halting Mosquito Surveillance Could Increase Costs

 A study published in PLoS Neglected Tropical Diseases "shows that halting mosquito surveillance can increase the management costs of epidemics by up to an order of magnitude in comparison to a strategy with sustained surveillance and early case detection." Using a mathematical model to create hypothetical scenarios "of delayed response to a dengue introduction (a consequence of halted mosquito surveillance) in the City of Cairns, Queensland, Australia" and "then coupl[ing] the results of such a model with mosquito surveillance and case management costs to estimate the cumulative costs of each response scenario," led researchers to conclude, "the total costs of preparedness through surveillance are far lower than the ones needed to respond to the introduction of vector-borne pathogens, even without consideration of the cost in human l ives and well-being" (Vazquez-Prokopec et al., 10/26).
