Per 
Description:
[SCP] is a form of parasite which manifests as a mysterious figure in the hosts visual-field. It is unknown how it manages to do this, if it's brain/optical manipulation, and it's also unknown how it manifests as a physical organism. However; it is known that it moves through physical contact, and upon moving it releases a toxin of deadly variety in the previous host's body.
This also brings us to the point that this is a Safe SCP, due to the fact that the parasite doesn't seem to have any impact on the host control-wise. The host is able to continue living in a almost usual fashion, but is to avoid ANY physical contact with other people.
Appearance:
Appearance is unknown, due to the fact that we are unable to locate a physical organism within the body of the host, and it's already extremely difficult because all physical contact must be avoided. However; subjects "describe" it as a jargled mess of unexplainable matter without a specific form. They explain it as an anomalous creature that seems to be always moving, but always standing still. Absorbing all light, but glowing like a stagelight. An incomprehensible mess, yet so elegant and organized.
Conclusion:
If kept away from people it should be relatively harmless. We also need to explore it further in form of what effect is has on the host, and where it manifests within the body.
