It was a genetically engineered biological weapon developed by United States scientists working under the aegis of the power groups that would later form the Enclave. The New Plague virus was actually a top secret military project, codenamed Limit 115.

The usual methods of controlling the spread of the disease were isolation and containment. Though the exact method of infection is unknown, the New Plague virus was highly virulent and could be easily contracted in any social situation. Should anyone survive the plague, they are rendered completely sterile by the virus. It may also result in clogged respiration, leading to death through asphyxia. The Plague eventually worsens, leading to profuse sweating, unexplained contusions and swelling, eventually terminating in massive external hemorrhaging. Initial symptoms greatly resemble the classic flu. The time of incubation of the virus varies, taking between three to five days.
