This week we are hosting Olga Vasilieva from Univalle (Colombia), to discuss new approaches to mitigate vector-borne diseases in both plants and human populations.

Yesterday we had the pleasure of attending her talk on control mechanisms to eliminate Diaphorina citri, super interesting!!!

4/4 Finally, we establish a general correspondence between our model and broader classes of competing social contagion dynamics with symmetry breaking, recovering previous results as limiting cases.

3/4 Groups induce discontinuous (explosive) transitions between fully honest and fully corrupt regimes, separated by a bistable phase!

Importantly, this abrupt behavior disappears in the pairwise limit, highlighting the destabilizing effect of group interactions.

2/4 We introduce a higher-order model to study the emergence of systemic corruption in populations where individuals interact through group structures. By including groups, we capture the influence of peer pressure in group settings.

6/6 To round off:

🚍 In itinere contagions are critical for understanding real-world epidemics in cities.

They reshapes both the magnitude and spatial profile of outbreaks—vital insights for designing effective containment strategies.

5/6 📍It doesn't end there….in itinere contagions are also a key force behind epidemic delocalization.

We find that they precipitate a transition from localized outbreaks (confined to vulnerable patches) to a widespread propagation.

🧭 This drastically shifts the spatial epidemic landscape.

4/6 🧨 In itinere contagion counteracts 🥊 epidemic detriment – the idea that mobility (up to a critical value) suppresses epidemic spread.

We show that transit-based infections reshape this boundary, modifying the critical conditions under which mobility boosts or suppresses epidemic outbreaks.

3/6 ⚠️ Including in itinere infections significantly lowers 🔻 the epidemic threshold and increases disease prevalence!

We show that neglecting in-transit infections leads to a serious underestimation of epidemic severity and population vulnerability. A hidden risk that standard models miss 🧩

2/6 Most metapopulation-based epidemic models assume people only spread disease within specific locations.

🚌 But what about infections acquired on the move?

We extended our MIR framework introducing infections that happen while commuting, in particular on public transport, key in urban settings.

5/5 Overall, our study pinpoints that balancing commuting and roaming can help contain outbreaks without drastic traffic cuts, offering insights for targeted interventions that reduce the risk of global epidemic spread.

4/5 We then explore the “invasion” threshold (i.e. how local outbreaks can become global 🌏) for low mobility scenarios.

Agents with low exploratory behavior spend less time in new places, reducing the spread window and raising the required mobility to generate a global epidemic.

3/5 By creating the new generation matrix, we obtain the epidemic threshold ⚠️.

Interestingly, it depends on how frequently agents return versus how much they roam:

Random-walk–dominated dynamics (low return, high mobility) typically yield a higher threshold for 🦠 to spread!

2/5 We developed a metapopulation formalism in which the key parameter is the “return” probability, blending commuting and exploratory behaviors in a balanced way:

High return → more commuting 🚌 (agents quickly go back), low return → more exploration 🧭 (random walks).
