Special Issue Information

Dear Colleagues,

Global changes in environmental conditions that favour a closer proximity between vector and host populations are facilitating the spread of arboviruses (arthropod-borne viruses) to both humans and other animals. These processes, which include climate change, urbanisation, trade, deforestation and migration, are interacting and evolving, creating a complex landscape of current and future transmission risk. For example, the recent emergence (2013-2014) and epidemic spread of the mosquito-borne Zika and chikungunya viruses has caused severe health and economic impacts in Latin America. Tick-borne viruses, although often receiving less attention by the research community compared to mosquito-borne viruses, are also on the rise (e.g., the Crimean–Congo haemorrhagic fever virus and African swine fever virus).

The evolutionary and host–pathogen history of arboviruses is vastly diverse, characterised by different geographical origins and current circulation ranges, a multitude of host and vector species, and even the presence or absence of antigenic variation. Universally, the spatiotemporal dynamics of arboviruses are primarily governed by the interplay between virus, vector and host. On the vector side, carrying capacity and seasonal oscillations in abundance are influenced by many biotic and abiotic factors. Climatic factors are recognised as particularly important because they significantly alter each vector’s potential to transmit the virus by directly causing changes in physical and behavioural traits.

In light of recognised ongoing climate change global trends, it has become increasingly relevant to understand how climate shapes the evolution and host–pathogen dynamics of arboviruses. This Special Issue aims to collate recent work focused on arboviruses in the context of climatic factors. All work exploring the role of past, present and future climate, whether of animal or human arboviruses, empirical or theoretical, is welcome. Original research articles and reviews are welcome.

We look forward to receiving your contributions.

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.

West Nile virus (WNV) is a public health concern in Europe. Rising temperatures and the migration of potential vectors promote the spread of viruses to previously unaffected areas. In 2023, the Apulia region of Southern Italy experienced an unexpected increase in West Nile neuroinvasive disease (WNND); no such cases had been reported in the previous 10 years. Overall, eight autochthonous cases of WNV infection were identified between July and October 2023, six of which were WNND. All cases were male (median age, 73 years). Two of the cases were blood donors. All WNND cases were hospitalized and all recovered within a few weeks. Surveillance data showed that, in the Apulia region, WNV Lineage 2 was detected in humans, mosquitoes, and horses. Based on the number of WNND cases reported, we can assume that a high number of infections occurred during the summer period. Changes in the climate in the region over recent years could be considered among the main drivers of the rapid increase in WNV infections. Therefore, integrated surveillance should be strengthened to avoid the potential massive spread of WNV in Southern Italy. Moreover, the implementation of whole-genome sequencing of WNV strains, as well as seroepidemiological studies in the area, will facilitate a better understanding of circulation dynamics.
