South Korea's Outbreak

South Korea's outbreak is a zombie outbreak that has occurred in South Korea in the movie Train To Busan.

History
The first outbreak to start was somewhere in the countryside. This is also supported when two men in biohazard outfits mentioned out a bio leakage near a bio factory. Later a man in a pick-up truck accidentally ran over a deer and simply drove off, not even bothering to check the deer. The deer shortly after came back alive as a zombie, thus presumably starting the outbreak there. The second outbreak was in Seoul. It was night when the outbreak broke out due to Seok-Woo coming back home unharmed, suggesting the outbreak has not broke out yet. The outbreak started just as Seok-Woo and his daughter entered the KTX, thus avoiding the outbreak of Seoul. Although a person (Runaway Girl) that was bitten managed to enter the train without being noticed. The next day the outbreak has occurred all over the country has cities were in a chaotic state while the military and police attempts to stop it to no avail. By the end of the day, they were successfully able to quarantine Busan. It is likely that U.S. Government may attempt to stop the spread of the outbreak and Seoul and other Korean cities except Busan will be bombed through the use of nuclear weaponry. This is wrong though as there is a prequel movie "Seoul Station" to explain the origin of the outbreak.

Four years later in Peninsula, Korean peninsula become abandoned and deserted after almost all of survivor escaped from outbreak four years ago leaving all infected stay behind.

Trivia

 * One of Seok-Woo's employee Kim mentioned that it was their company's fault for the outbreak of Korea. Due to saving a bio company (the same company that had a leakage earlier in the movie) from bankruptcy.
