With regard to the economical impact, there is some evidence that even stockpiling of the costly neuraminidase inhibitors might be cost-beneficial for treatment of patients and, ifbacked by adequate stocks, for short-term postexposure prophylaxis of close contacts (Balicer 2005).
Con respecto al impacto económico, hay algo de evidencia de que incluso almacenar los costosos inhibidores de la neuraminidasa podría ser costo beneficioso para el tratamiento de pacientes y, si fueran financiados por reservas adecuadas, para una rápida profilaxis de post exposición de los contactos cercanos (Balicer 2005).
I'd like to understand the meaning of this long sentence.
First of all, is "costo beneficioso" the equivalent for "cost - beneficial"? I thought it was "cost-benefit" that's why I am asking you.
Then, what does the verb "back" mean in that context?? I swear I'm lost
