Can a prison official be held liable for deliberate indifference to medical needs?

These allegations lack sufficient detail to establish an Eighth Amendment deliberate indifference to medical needs claim. To act with deliberate indifference, a prison official must both be aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference. Farmer v. Brennan, 511 U.S. 825, 837 (1994). Thus, a defendant is liable if he knows that plaintiff faces "a substantial risk of serious harm and disregards that risk by failing to take reasonable measures to abate it." Id. at 847.
