Special Issue Information
Dear Colleagues,
Since the first severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant Alpha was identified in England in late November 2021, mutations in the viral genome can increase transmissibility, facilitate escape from the human immune system, and/or alter biologically important phenotypes. The SARS-CoV-2 variants are classified as variants being monitored (VBMs), variants of interest (VOIs), variants of concern (VOCs), and variants of high consequence (VOHCs). There are two currently circulating SARS-CoV-2 VOCs (Delta and Omicron), and three previously circulating VOCs (Alpha, Beta, and Gamma) in a way that confers a fitness advantage to the virus, such as mutations in the spike (S) gene that affect antigenicity. Each characterized variant has mutations in the gene encoding the S protein (Omicron: 30 mutations; Delta: 10 mutations; Alpha: 7 mutations and 2 deletions; Beta: 9 mutations and 1 deletion; and Gamma: >10 mutations), compared to the sequence of the wild type index virus (Wuhan-Hu-1).
Previous studies have pointed out that viral genomic mutations leading to new variants of SARS-CoV-2 are a real challenge in tackling the global coronavirus disease (COVID-19). Understanding SARS-CoV-2 variants remains an issue of concern for all local government authorities and are critical for establishing and implementing effective public health measures.
This Special Issue on “Detection and Assessment of SARS-CoV-2 Variants” will cover all related areas, such as diagnostic applications, VOC pathogen detection, biomarker monitoring, and others of concern.

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. Diagnostics is an international peer-reviewed open access semimonthly 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.
