The present study has shown that on the level of the parasitic system the epidemic process is a biological system, wherein the host population serves as the internal regulator, the mechanism of transmission serves as the external regulator and the parasite population, as the regulated object. The biological regulating mechanisms of the epidemic process have fundamental differences in the groups of infectious with various mechanisms of transmission, and the specific nature of the mechanism of transmission determines the peculiar features of the biological mechanism which governs the self-regulation of the epidemic process. In contrast, on a higher level of the organization of the epidemic process, i. e. on the level of the socio-ecological system, the epidemic process is a biosocial system, wherein the human society serves as the regulator, the parasitic system serves as the regulated object and the mechanism of transmission plays the role of the filter which determines the scope of social factors, most important in the regulation of the epidemic process in a given infection. The spontaneous regulation of the epidemic process is the freed forward channel from the regulator to the regulated object, and the controlled regulation is the feedback channel.
本研究表明，在寄生虫系统层面，流行过程是一个生物系统，其中宿主种群充当内部调节器，传播机制充当外部调节器，而寄生虫种群则作为被调节对象。流行过程的生物调节机制在具有不同传播机制的传染病组中存在根本差异，传播机制的具体性质决定了控制流行过程自我调节的生物机制的独特特征。相比之下，在流行过程组织的更高层面，即在社会生态系统层面，流行过程是一个生物社会系统，其中人类社会充当调节器，寄生虫系统充当被调节对象，传播机制起到过滤器的作用，它决定了在特定感染的流行过程调节中最重要的社会因素的范围。流行过程的自发调节是从调节器到被调节对象的前馈通道，而受控调节是反馈通道。
