Legato infection

Legato infection was a type of disease, a plasma plague that was known to the Federation's scientists in the late 23rd century

In the year 2294, there was a plasma plaque outbreak on the northern continent of planet Oby VI. While studying the Oby VI infection, a research team led by Doctor Susan Nuress compared the outbreak strain t the Legato infection in the hopes that similar treatments could be used, but the Oby strain was different and resisted treatment. Mutations of the Oby VI strain carried the comparisons to other strains in an etiological report when stored by Starfleet Medical.
