Do you mean the victims or the instances of SCP-3008-2? I don’t think the anomaly itself is curable.

Summary for those not familiar: SCP-049 is a plague doctor that seeks to violently “cure” anyone afflicted with some nondescript “Pestilence”.
SCP-3008 is an endless and nearly inescapable IKEA, where the “Staff” (labeled SCP-3008-2) are entirely unresponsive during the day but become violent at night towards anyone still in the store after closing time.
