It's peak cold and flu season, which means taking a lot of preventative measures.

Frequent hand washing is a must, as is avoiding coworkers or friends who are sick.

But we humans are not the only animal that change behavior to keep diseases at bay.

So do ants. So the 4-Hagers and the nurses, it's two different groups of work. Natalie Stromitt of the University of Lucian.

She and colleagues observed ants to see their reaction to the presence of a pathogen.

With the nurses staying inside the nest, taking care of the broods and being made of young

workers typically.

And the foragers are all the workers that go outside of the nest to collect food and defend

the territory.

Forager ants are at a greater risk of getting exposed to diseases because they leave the

safety of the nest.

So the researchers sprayed a common fungus on a small group of forger ants and then

followed their movements to see the way the other ants reacted.

We marked all ants in the colony with individual labels which carries these two-dimensional

barcode marks like QR code, which is automatically detected and recorded using a tracking

system. After the infection, the nurse and forager ants stayed within their clicks and interacted
