**The answer is a bacterial infection. Pus forming around a cut is the body's visible sign that bacteria, not a virus or fungus, are the problem.**

Viral infections, fungal infections, and parasitic infestations don't typically produce pus the same way. Recognizing pus specifically as a bacterial signal, not just a general "something's wrong" sign, is the useful distinction here.
