Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Instances of SCP-XXXX-1-B are to be contained in a humanoid containment cell modified to have an open floor plan and equipped with additional amenities to support all contained instances. A proposal to construct a cell more suitable for mass cohabitation is currently under review.

No item whose special containment procedures require uninterrupted visual contact is to be stored at the same site as any instance of SCP-XXXX-1.

Essential personnel afflicted with SCP-XXXX are to be isolated immediately and treated for lagophthalmos. Artificial tears for this purpose are to be stored on-site. Care is to be provided exclusively by remote equipment or, if unavailable, D-Class personnel.

Other personnel afflicted with SCP-XXXX are to be terminated contained with the other SCP-XXXX-1 instances, but otherwise allowed to retain position and some clearance provided that they make no attempts to breach containment. (See Addendum 1)

As a precaution, personnel assigned to SCP-XXXX are to avoid congregating in groups of two or more for periods exceeding 10 minutes at a time within 30 meters of any SCP-XXXX-1.

SCP-XXXX-1-B instances are to be removed from the presence of other SCP-XXXX-1 (using life support equipment to prevent expiration) for at least an hour every 30 days. (See Incident 1)

All contained SCP-XXXX-1 are to be equipped with remote detonation collars in case simultaneous termination is required. (See Incident 1)

Description: SCP-XXXX is a phenomenon causing the bodily functions of affected individuals (designated SCP-XXXX-1) to be synchronized, such that they are performed simultaneously by all SCP-XXXX-1 instances.

The effects of SCP-XXXX are spread to any person remaining in proximity (approximately 5 meters or visual range) to an SCP-XXXX-1 instance for a length of time observed so far to be no less than 17 12 minutes. Personnel that have been exposed to SCP-XXXX for more than 10 minutes are to be assumed to be instances of SCP-XXXX-1 regardless of symptoms.

Upon first becoming afflicted by SCP-XXXX, an instance is designated as SCP-XXXX-1-A. At this stage, the subject will blink simultaneously with all other SCP-XXXX-1 in range, and will cease to blink altogether when not in the presence of other SCP-XXXX-1. The instance will otherwise display no anomalous activity, and may react to their condition.

After remaining in the presence of other SCP-XXXX-1 for approximately 4 hours, an instance is redesignated SCP-XXXX-1-B. This encompasses all remaining (see Incident 1) stages of affliction, beginning with the synchronization of breathing at 4 to 6 hours of exposure and culminating in the synchronization of the heartbeat at approximately 15 to 21 hours of exposure. When not in the presence of other SCP-XXXX-1 instances, the affected functions will cease entirely until another instance is in range or the instance expires.

As SCP-XXXX-1-B are no longer capable of surviving in the absence of other SCP-XXXX-1 without extensive life support, they are considered lower-risk than SCP-XXXX-1-A they are more prone to aggressive behavior if they suspect that they or another instance is to be isolated.
