Kijuju Autonomous Zone Incident

History of the Outbreak
A few years after the events in Resident Evil 4 the Tricell Pharmaceutical Company acquired the Las Plagas Parasite thanks to Albert Wesker. They proceeded to enhance them for sale on the black market for bioweapons. Tricell employee Ricardo Irving traveled to the Kijiju Autonomous Zone, planning to sell the weapons. However, when the B.S.A.A discovered this, he moved the deals and started to release the Plagas in 2008. By 2009, Las Plagas had spread throughout the area.

The outbreak
After Tricell unleashed the parasite, the people of Kijuju began to act strangely, even leaving headless animals on the streets. At the same time, the natives became more hostile towards outsiders. This eventually led to active racism and violence. By the time that B.S.A.A. operative Chris Redfield arrived, public executions were accepted. The cause was Type 2 Plagas. To prevent the spread of the infection, the Kijujian Armed Forces built a wall to prevent infected Kijujians from leaving.

The B.S.A.A
The B.S.A.A. sent in Alpha team, a group of commandos, to arrest bio-weapons dealer Ricardo Irving and to control the situation. Chris Redfield and Sheva Alomar, B.S.A.A. operatives, were sent in as backup but failed to arrive in time to save alpha team. During their absence, Irving released the Uroboros virus and destroyed Alpha team. Once it was defeated, Irving then released other bioweapons, such as Popokarimu and a Ndesu in an attempt to defeat the remaining two operatives. These bioweapons destroyed the B.S.A.A. Delta team through their sheer force.
