Are chain reaction outbreaks considered part of the original outbreak, in regards to "Containment Failure"
Pandemic co-creator Tom Lehmann gave an example (answering another question, admittedly) indicating that further outbreaks add only one cube.


  In your Manila/Taipei example, each with three cubes, you will first place 2 cubes in Hong Kong, Shanghai, and Osaka; then do one chain reaction outbreak in Manilla, placing cubes in San Francisco, Sydney, Ho Chi Minh City, and Hong Kong, for a total of 10 cubes and 2 outbreaks.
