Accomplishments and challenges in picornavirology as observed by a medical doctor
1Institut für Virologie, Universität zu Köln, Germany.
Background:
The family of picornaviridae has been studied extensively: the structure of the virion and its replication strategy are known in molecular detail. Nevertheless, infections with the multitude of enteroviruses still cause widespread epidemics, serious disease and a diversity of clinical syndromes ranging from central nervous system involvement to light febrile illness. Infections with more than 100 human rhinovirus types are an important economic factor.
Objective:
In order to treat and control picornavirus infections with their great diversity of manifestations the pathogenesis of diseases must be better understood, e.g. concerning virus spread in the organism or molecular detail of the disease processes, such as cell tropism of the virus or cytokine and immunologic actions. Elucidation of mechanisms of virus transmission in the population is also needed.
Study Design:
This review discusses aspects of our present knowledge of the pathogenesis, transmission, prophylaxis and treatment of picornavirus infections.
Conclusions:
The need for further development of selective antiviral substances, safe vaccines and basic research in picornavirology is stressed.
