[Persistent virus infections and their sequelae]
Abstract:
Besides acute virus diseases, persistent virus infections have attracted increasing attention during the last few years. In the case of such infections, the infecting virus may remain in the host organism for months or even years, before symptoms appear. These persistent virus infections can be caused by different viruses and may lead to a variety of pathogenic reactions and clinical manifestations. As far as knowledge goes, the mechanisms underlying a virus persistance are equally different. Within the space limitations, an attempt is made to present such mechanisms and to derive from them the pathogenesis of the follow-up diseases.
Insights
Persistent virus infections, where viruses remain in hosts for extended periods before symptoms manifest, are gaining attention. This review explores the diverse mechanisms causing viral persistence and their role in subsequent disease development.
Area of Science:
- Virology
- Immunology
- Pathogenesis
Context:
- Growing interest in persistent virus infections beyond acute viral diseases.
- Viruses can remain latent in host organisms for months or years.
- These infections are linked to various pathogenic reactions and clinical outcomes.
Purpose:
- To elucidate the diverse mechanisms underlying viral persistence.
- To connect these mechanisms to the pathogenesis of subsequent diseases.
Summary:
- Persistent viral infections involve prolonged presence of viruses in hosts.
- Mechanisms of persistence vary significantly between different viruses.
- Understanding these mechanisms is key to understanding follow-up disease development.
Impact:
- Provides insights into the complex interplay between viruses and host organisms.
- Highlights the importance of studying viral persistence for disease prevention and treatment.
- Contributes to a deeper understanding of chronic viral pathogenesis.
