With the use of a set of general and special methods and techniques of scientific cognition:: logical-semantic, structural-functional, abstraction, formal-logical, comparative-legal, theoretical-prognostic, analysis and synthesis, inductive and deductive, statistical and other outlined research methodology.
The development of forensic science is covered as a natural, taking into account the needs of practice, which determines the need to form the toolkit with the use of which the goals of criminal proceedings are achieved, where the existing methodological, organizational, tactical, nature of recommendations is the basis for the formation of new theoretical developments that focus on the peculiarities of activity in an epidemic (pandemic).
The multifaceted problems of ensuring the conditions of people's activities during the epidemic (pandemic) in general and conducting investigative (search) actions in particular with the search for ways to solve it in the context of the tasks of the relevant departments of the Ministry of Health of Ukraine, Labor and Social Policy of Ukraine, the Ministry of Internal Affairs of Ukraine and others.

The most dangerous infectious diseases that have become widespread in the world and our country are given, with the analysis of statistical data, methods of distribution, the main syndromes of diseases and measures aimed at protecting against infection. The value of tracking the symptoms of diseases, the obvious absence of which does not determine the safety of contact with the relevant subjects, because it can be characteristic of the incubation period of the development of infectious diseases, which determines the need to perceive all participants of investigative (search) actions, unauthorized persons, objects with which they have to face, for example, during inspection, search, etc., as potential carriers of them.
The system of typing of persons (offenders and victims of criminal offenses) carried out on the basis of the traced dynamics of statistical reporting on the sex-age characteristics of subjects with whom authorized persons have to conduct investigative (search) actions in modern conditions, including those caused by the COVID-19 pandemic, as the basis for decisions of organizational, tactical and other nature, has been proposed.
A set of factors has been formed in determining the principles of organizing and conducting investigative (investigative) actions during an epidemic (pandemic), with the allocation of components of such of them as the armed aggression of the Russian Federation against Ukraine, which increase the risk of infection with especially dangerous infections, allowing to build general ideas about the processes and phenomena that form the appropriate conditions for the implementation of the tasks of criminal proceedings by authorized persons.
