So TB didn’t exist when people migrated to the Americas?
Is there any crappy disease that didn’t originate in Africa?

Syphilis. It's thought that syphilis came from South American "yaws" (actually it's found tropically, including Africa) that when transmitted to Columbus et al, the European dress styles and bathing habits, that is, lack of sunlight on the infected lesions, and minimal washing of both clothes and body, prompting the bacteria to mutate to what is now called syphilis.
Yaws can be transmitted through casual contact as well.

A poster to promote AIDS awareness ahead of World AIDS Day in Beijing. A highly contagious AIDS-like disease is spreading in China, However, HIV tests come up negative.
In a small hotel across from the Beijing Center for Disease Control and Prevention, a reporter from New Express Daily, dressed in an isolation suit, interviewed a dozen “unusual” patients from different areas of China.
