Since the Australasian Government announced nationwide quarantine, the number of immigrants heading from Europe to Australasia has almost halved.
Although the appeal of immigration to Australasia indeed is high, most immigrants are reluctant to accept the quarantine system of Australasia, let alone under the premise where nothing has happened yet.
Arthur doesn't care about this at all. Once the influenza outbreak occurs, these people will realise how cherished the quarantine system is.
Furthermore, Australasia's free treatment and supplies for its citizens would certainly attract more immigrants.
The influenza first broke out in the Kansas Army Camp in the United States, which is also a means for Arthur to sanction the United States.
As long as they wait until the influenza is serious and then propagate, the appeal of immigration to the United States will certainly plummet.
