However this is where your theory could be wrong according to this website https://www.avert.org/professionals/history-hiv-aids/overview
“It is widely believed that HIV originated in Kinshasa, in the Democratic Republic of Congo around 1920 when HIV crossed species from chimpanzees to humans. Up until the 1980s, we do not know how many people were infected with HIV or developed AIDS. HIV was unknown and transmission was not accompanied by noticeable signs or symptoms.”
And the Joseon dynasty ended in 1910.
I feel like its aids, right? If its contagious, but the symptoms come and go.
