I was going to make fun of the title (which is basically “Sick ants stink, the others don’t like it and make it stop”) but IMO this is the important bit:

Then, the team conducted an experiment showing that the sick pupae only produce the smell when worker ants are nearby, proving it is a deliberate signal for destruction.

That does go beyond just smelling bad due to illness.
