This game is extremely virulent and can be transmitted through physical contact (via the dual “Nintendo 3DS” and “PlayStation Vita” retail vectors) as well as through the air (via the “PSN” vector), which has prompted the IDO to declare this a level 6 pandemic. All uninfected persons are advised to remain indoors and avoid contact with others. If you suspect you have been infected, or suspect a friend or family member of being infected, report, or have them report, to the nearest IDO quarantine facility.
