几种突发疾病的同时出现或多株疾病的某些血清型的灭绝是在同一种群中传播的病原体之间相互作用的指纹。在这里，我们提出了一个通用的和通用的基准来解决合作和竞争相互作用疾病的展开。我们描述了由病原体之间的合作而产生的无病和流行制度之间的爆炸性转变，并显示了这种突然转变的开始所需的临界合作程度。对于竞争疾病，我们描述了相互排斥的情况，并分析得出了只有一种病原体繁殖的完全优势阶段和共存状态之间的过渡点。最后，我们使用这个框架来分析前一个过渡点在病原体之间竞争放松时的行为。
The simultaneous emergence of several abrupt disease outbreaks or the extinction of some serotypes of multistrain diseases are fingerprints of the interaction between pathogens spreading within the same population. Here, we propose a general and versatile benchmark to address the unfolding of both cooperative and competitive interacting diseases. We characterize the explosive transitions between the disease-free and the epidemic regimes arising from the cooperation between pathogens and show the critical degree of cooperation needed for the onset of such abrupt transitions. For the competing diseases, we characterize the mutually exclusive case and derive analytically the transition point between the full-dominance phase, in which only one pathogen propagates, and the coexistence regime. Finally, we use this framework to analyze the behavior of the former transition point as the competition between pathogens is relaxed.
