Can influenza spread to other countries

europa-universalis-iv

When you get the Influenza event, you have two choices:

  • Quarantine the port and let the die!
  • This is not the first flu in our country, I don't care!

If I don't care, there's a 75% chance of spreading to neighboring provinces. Does this include neighboring provinces owned by other countries, or does the flu respect borders?

Best Answer

Quote from the wiki on this:

Option: This is not the first flu in our country, I don't care!:

The owner of the province: Changes administrative power stored by -5 Adds the modifier "Influenza" until the end of the campaign: province_trade_power_modifier = -1.0 -50% manpower modifier -50% provincial tax income -50% trade goods output

If: Limited to: Any bordering province: The province is owned by our country

Does not have the province modifier "Quarantined Influenza" Does not have the province modifier "Influenza" Randomized by Acquisition chance: Random bordering province:

Limited to: The province is owned by our country Does not have the province modifier "Quarantined Influenza" Does not have the province modifier "Influenza"

I have in the past chosen the "Don't care" option a couple of times and I can confirm that my flu has never crossed into another country.
