Have you not been reading the articles? Treatment is nothing but keeping them hydrated and as comfortable as possible. It has to run its course until the patient recovers or dies. Now, please tell me how brining them here is helping them one bit. It's certainly not helping to keep it contained. It's certainly not helping to keep it out of the US. It's certainly not helping with a mistake and letting them infect others.
According to wiki:
“No ebolavirus-specific treatment exists.[52] Treatment is primarily supportive in nature and includes minimizing invasive procedures, balancing fluids and electrolytes to counter dehydration, administration of anticoagulants early in infection to prevent or control disseminated intravascular coagulation, administration of procoagulants late in infection to control hemorrhaging, maintaining oxygen levels, pain management, and administration of antibiotics or antimycotics to treat secondary infections.”
Sounds like more than giving them water to me.
