Post-Viral Syndromes Following Respiratory Virus Infections: Virological Mechanisms, Therapeutic Approaches, and Long-Term Management

Dear Colleagues,

Respiratory viruses such as SARS-CoV-2, influenza viruses, and respiratory syncytial virus (RSV) cause significant acute morbidity and, in many cases, lead to persistent post-viral syndromes. These include long COVID and analogous conditions characterized by fatigue, cognitive dysfunction, respiratory issues, cardiovascular complications, and neuropsychiatric symptoms. The underlying virological mechanisms include viral persistence, immune dysregulation, autoimmunity, microvascular abnormalities, and the potential reactivation of latent viruses. Emerging research has also highlighted the role of nutritional factors, including dietary patterns and micronutrients, in modulating immune responses, reducing inflammation, and supporting recovery. This Special Issue will feature original research articles, reviews, and short communications addressing epidemiology, pathogenesis, host–virus interactions, diagnostic tools, therapeutic interventions (including pharmacological and non-pharmacological approaches), and management strategies—such as dietary and lifestyle interventions—in post-viral syndromes associated with respiratory viruses. By encompassing a broader range of viruses and interdisciplinary perspectives, including nutrition and rehabilitation, we will elucidate shared mechanisms and virus-specific features to help advance prevention, treatment, and long-term care for affected individuals.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Viruses is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
