I found it a very interesting gameplay idea and I liked the visuals and the atmosphere. 

As a point of feedback, I think it would be nice to add a bit of extra explanation for game mechanics, because Im not sure if there is a way to find out of the country is infected besides running multiple playthroughs.
But overall I really liked it and a good job!

First of all, congratulations on the art, music, and overall atmosphere you created. Awesome job! I really enjoyed it, and I think it fits the theme really well. 🦆

On the gameplay side, maybe I just missed something, but I got stuck during the second shift. After being told to enter the Oceania code, the Enter button seemed to add an extra 0, so I never managed to get it right.

Then I opened the communication with the previous worker telling me to finish the job early, but when I clicked "End Shift" I got an "invalid authorization" message or something similar, so I ended up getting stuck there.

I'm not sure if I clicked something wrong or missed a step, but either way, this is still very impressive work for a game jam. You should feel really proud of what you made!
