Treatment
There is currently no FDA-approved ebolavirus-specific therapy for EVD. 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. Hyperimmune equine immunoglobulin raised against EBOV has been used in Russia to treat a laboratory worker who accidentally infected herself with EBOV—but the patient died anyway. Experimentally, recombinant vesicular stomatitis Indiana virus (VSIV) expressing the glycoprotein of EBOV or SUDV has been used successfully in nonhuman primate models as post-exposure prophylaxis. Such a recombinant post-exposure vaccine was also used to treat a German researcher who accidentally pricked herself with a possibly EBOV-contaminated needle. Treatment might have been successful as she survived. However, actual EBOV infection could never be demonstrated without a doubt. Novel, very promising, experimental therapeutic regimens rely on antisense technology. Both small interfering RNAs (siRNAs) and phosphorodiamidate morpholino oligomers (PMOs) targeting the EBOV genome could prevent disease in nonhuman primates.

Famous quotes containing the word treatment:
“The treatment of African and African American culture in our education was no different from their treatment in Tarzan movies.”
—Ishmael Reed (b. 1938)
“Judge Ginsburg’s selection should be a model—chosen on merit and not ideology, despite some naysaying, with little advance publicity. Her treatment could begin to overturn a terrible precedent: that is, that the most terrifying sentence among the accomplished in America has become, “Honey—the White House is on the phone.””
—Anna Quindlen (b. 1952)
“James’s great gift, of course, was his ability to tell a plot in shimmering detail with such delicacy of treatment and such fine aloofness—that is, reluctance to engage in any direct grappling with what, in the play or story, had actually “taken place”Mthat his listeners often did not, in the end, know what had, to put it in another way, “gone on.””
—James Thurber (1894–1961)
