[zombies in general] A single zombie is released in the world. Which is the best chance it got to spread the virus?

Well that. A single zombie in the world that can only spread its virus by just biting people. Which place is its best option?
gpt
Somewhere tightly packed, with a large and preferably ageing population.

Although it would all depend on the specifics of the type of zombie. 

- are they fast or slow?

- how long does it take to turn?

- do they still look human or are they noticeable from the start?

- does the virus just spread through bite, through any fluids, or are we already all infected?


Also, our current situation would suggest China would be a good suggestion.
