It's a creature. SCP-049 "Epidemiologist" is a humanoid SCP creature in the mysterious literary story series of SCP Foundation. The shape of SCP-049 is similar to that of Dr. Bird's beak in the Middle Ages, wearing a black robe and a bird's beak mask. It seems that the mask and clothes are part of the body of SCP-049.

SCP-049 thinks that human beings have a plague and will try to kill these individuals and perform unknown surgery on the corpses. SCP-049 thinks he's treating them. However, these bodies are usually transformed into a zombie-like brainless creature (named SCP-049-2), but 049 claims that they have been cured.
