Prevention requires investment in redundant network infrastructures as well as well-developed training and contingency planning.

Opportunism. Just as many companies have "dumped” products into developing markets that have been deemed inappropriate in developed nations (Cultural Survival, n.d.), there is substantial risk that the legacy e-health products referred to above will be sold into developing markets, introducing unnecessary barriers to health system improvements.
