So I'm asking you for one.

Or was "E. Coli is in China" your answer, posed with a question mark at the end (implying that, because E. Coli is in China, most viruses and bacteria are therefore international)?
You won't find an article confirming that most species of virus and bacteria are international because it is common knowledge. I really think you're either over thinking this or you don't understand what I'm saying. When you step off a plane in China, your first breath probably contains a thousand different species of bacteria. Understand? And I'm not saying China is not clean, because the same is true anywhere. Every one of those species of bacteria would become some sort of disease if your immune system didn't kill it. The fact that people don't drop dead when they leave the country proves that pathogens are international.
