Re: Same lock
The notes said that the original infected was a young boy. It became airborne. It's not actually a plague, although I can see why people would assume that. It was a modified ebola virus strain that appeared similar to bubonic at first. The thing is the symptoms showed later in the infected period, meaning that by the time the symptoms showed, it was already spread more.
The one before me got samples and once he got it under the microscope he would see that it was ebola. If it was caught early, it could be treated with acyclovir, but it wasn't caught early. He used the samples to create a vaccine and antiviral to combat it. But this was highly tweaked, whoever did make it knew exactly what they were doing.
