The Metamorphosis Plague is caused by a virus that rewrites the DNA of the subject transforming them from one race into another race. The first outbreak of this plague occurred in Year 4. During that time the plague was confined to the Human species and others were unscathed by the outbreak.
A decade after its first appearance, however, the plague returned. It was inadvertently released by scientists trying to find a cure for the Great Animosity Plague that had broken out on Derra IV on Year 14 Day 1. The release occurred on Year 14, Day 25. Unlike its predecessor, this new strain of the plague affects all known sentient species. Scientists predict it will run its course within a month.
A very volatile disease, once a victim mutates into a different species, a brief lapse in memory has been recorded to occur. After a subject's genome settles, memory is restored; however, in some special cases, it has been noted that few subjects recall learning new trades or abilities while completely forgetting others. From the few cases that have been observed the actual transformation process is shown to be extremely painful.
As with the first strain of the disease, many victims have been observed to show no memory of the way they were before, even going so far as to create elaborate stories to reason away their transformation. Researchers speculate that this is most likely a psychological defense, rather than an actual side effect of the plague.
Some victims have also reported becoming infertile after the violent transformation; however, this effect appears to be rare, reported in approximately 1 out of every 100 cases.
Some beings have actually been known to fight off the transformation. It is unknown what allows these beings to stop the plague's progress, but all studies into this have turned up inconclusive. However once the transformation has been initially resisted, it does not resurface.
Cures and Prevention
Early estimates reveal that Humans and species closely related to Humans are nearly five times as likely to be affected by the plague as other species. This indicates that Humans remain as vulnerable as during the Year 4 outbreak and have not developed antibodies against this new strain of plague. Of non-Humans, Falleen and Gand appear to be significantly more susceptible than others.
Humans also represent the most commonly observed result of the plague's genetic mutation, with Corellians, Hapans, Kiffar, and standard Humans in the lead. This is followed closely by the Kaleesh, and both Anzati and Abyssins appear common in addition. However, these numbers continue to fluctuate as the plague runs its course, and these data may change as new plague victims turn themselves in to medical authorities for treatment. It is not known whether the species of the plague carrier by which each victim is affected has any bearing on the nature of the genetic modification, but as of yet, few data support that hypothesis.
