Item #: SCP-XXXX
Item Class: Euclid
Special Containment Procedures: All instances of SCP-XXXX-2 are to be contained in Model X3 Cryogenic storage units. Temperature should be maintained at roughly -155 degrees C. The current containment facility is located at Site 57. All developing instances of the infection should be taken in for testing immediately. It is to be noted that all known instances of SCP-XXXX-2 are currently in containment, so hunting for instances is not a priority.
Description: SCP-XXXX-1 is a fungal infection. It is spread by a victim (who now has the appearance of a level-B hazmat operative), known as SCP-XXXX-2, placing his fungal gas mask upon another’s face. Instances of SCP-XXXX-2 tend only to infect it's target when they are alone, and would be expected to remain alone for the following eight-hour infection period. They stalk their victim until such an opportunity arises. At this time they place their gas mask upon the victims face and, if they are not in REM, deploy a narcotic via it.
The infection starts as a fungal rash originating from the location of the gas mask. This is known as phase one and lasts roughly three hours. Once it covers the whole body, a level-B hazmat suit begins to form around the body of the victim. This is known as phase two and lasts roughly five hours. This suit appears as a normal hazmat suit, but it is actually fungal in composition. Once complete, the subject awakes and begins locating another victim. When the gas mask is on a developing instance they cannot be awoken by any means, and appear to be in a coma-like state. However, the gas mask may be removed if the infection is still in phase one, in which case the subject may be awoken and studied. If the subject is in phase two of infection, than the gas mask may not be removed without killing the subject.
If an instance of SCP-XXXX-2 is killed, either by removal of the mask or any other means a large spore burst is released from the subjects body. This spore burst can be counter acted by a typical gas mask, but is prone to enter ventilation systems and exit through windows, doors, and walls lacking insulation. Infection by spore is less likely to happen, but a single spore burst is capable of infecting dozens of people.
Communication with SCP-XXXX-2 seems impossible. If not accompanied it will remain dormant, and when approached by more than two individuals begins to panic. Individual containment appears to be not much of an issue, but they also do not pose much research contribution.
Addendum XXXX-AU: Autopsy performed. Suit cannot be removed by normal means, and must be cut open. Fungal growth continues inside of the body. Fungus has completely enveloped the heart, presumably to manually pump it well after the initial subject has lost the power to do so. A similar phenomenon occurs with both lungs. Most of brain has succumbed to the infection. The only areas free of infection are the frontal lobes. Muscles in the arms and legs are also laced with fungus, effects unknown.
