Quantum field theory has revealed that diseases spread through 'teleporting' super-spreaders rather than simple neighbor-to-neighbor contact.

Fractional epidemics from quantum loops

The Takeaway
By treating a virus outbreak like a field of interacting subatomic particles, researchers found that epidemics naturally undergo 'Lévy flights.' This means outbreaks are mathematically driven to make massive, unpredictable leaps across long distances, explaining why real-world pandemics move in sudden 'avalanches' rather than smooth waves.
From the abstract
Classical compartmental models of epidemiology rely on well-mixed, local interaction approximations that fail to capture the heavy-tailed burst dynamics and long-range spatial correlations observed in real-world outbreaks. While fractional calculus is frequently employed to model these anomalous behaviors, fractional operators are introduced phenomenologically. In this work, we demonstrate that fractional space-time epidemic dynamics emerge naturally and rigorously from first principles using a
