(Scp-129~P.F.I)

Item #: SCP-129 Object Class: Keter Special Containment Procedures: SCP-129 is at large in the world and infects large numbers of humans and animals daily. As such, containment efforts are focused on treatment of infected individuals and on eradication of any or all member species of SCP-129. Although at least 98% of the world's population harbors a natural immunity to one or more species of SCP-129, outbreaks that reach Stage Three or higher (described below) must be contained as quickly as possible, with infected individuals quarantined under highest-risk contagion protocols. See Document #129-A-1 for further information. In the event of Stage Four or Stage Five outbreak, in addition to the above procedures, [DATA EXPUNGED], as described in Document #129-A-2 (Level 4 clearance required). Description: SCP-129 is a series of at least ██ different species of fungus that can infect any animal with mucosal membranes. Infection by SCP-129 can pass through up to five stages (depending on exposure to further member species of SCP-129, individual resistance, and other factors), with each stage of infection facilitating progression to the next stage by weakening the individual’s resistance to subsequent infection. Due to a combination of historical events, most humans and animals are naturally immune to SCP-129-04 through SCP-129-██. Therefore, outbreaks of Stage Three infections are quite rare, but have the potential for widespread infection if not swiftly isolated and contained. All known cases of SCP-129 have followed the below five-stage progression, although [DATA EXPUNGED], possibly due to mutation. Stage One: The first organism, SCP-129-01, attacks the victim's mucosal membranes, multiplying quickly and unobtrusively. A faint yeast-like smell might be detected, but beyond that, SCP-129-01 is asymptomatic.
