Special Issue Information

Dear Colleagues,

Viral respiratory infections are the most common diseases in humans, contributing to substantial morbidity, mortality, and economic losses annually worldwide. As the world continues to deal with COVID-19, upsurges in infections caused by other respiratory viruses, such as influenza, respiratory syncytial virus, parainfluenza, metapneumovirus, bocaviruses, and non-rhinovirus enteroviruses, have burdened healthcare systems in several countries. Because of their transmissibility, advances in the diagnosis and surveillance of these respiratory viruses are critically needed to guide the use of available therapeutics, the allocation of hospital as well as community resources, and the targeting of vaccination in addition to behavioral change campaigns by public health officials to mitigate their spread. Furthermore, since many of these respiratory viruses have limited therapeutic options and lack effective vaccines, there is an urgent need for further research into the biology of these viruses to help guide the development of effective strategies for the treatment and prevention of infection.

This Special Issue of Viruses seeks to attract original research and review articles focused on (1) advances and innovations in the development of highly sensitive diagnostic tests for the early detection of human respiratory virus infections; (2) timely findings on the epidemiology and transmission of human respiratory viruses; (3) the development and clinical trials of new vaccines, antivirals, and immunotherapeutics for influenza, RSV, coronaviruses, and other clinically relevant human respiratory viruses; (4) studies detailing the effectiveness and/or immunogenicity of existing vaccines; and (5) mitigation measures or strategies to reduce viral transmission/community spread, disease incidence in at-risk populations, and cross-species transmission.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Porcine astrovirus 4 (PoAstV4) has been recently associated with respiratory disease in pigs. In order to understand the scope of PoAstV4 infections and to support the development of a vaccine to combat PoAstV4 disease in pigs, we designed and produced a recombinant PoAstV4 capsid spike protein for use as an antigen in serological assays and for potential future use as a vaccine antigen. Structural prediction of the full-length PoAstV4 capsid protein guided the design of the recombinant PoAstV4 capsid spike domain expression plasmid. The recombinant PoAstV4 capsid spike was expressed in Escherichia coli, purified by affinity and size-exclusion chromatography, and its crystal structure was determined at 1.85 Å resolution, enabling structural comparisons to other animal and human astrovirus capsid spike structures. The recombinant PoAstV4 capsid spike protein was also used as an antigen for the successful development of a serological assay to detect PoAstV4 antibodies, demonstrating that the recombinant PoAstV4 capsid spike retains antigenic epitopes found on the native PoAstV4 capsid. These studies lay a foundation for seroprevalence studies and the development of a PoAstV4 vaccine for swine. Full article
