Parvoviruses of Aquatic Animals.

Family consists of small, non-enveloped viruses with linear, single-stranded DNA genomes of approximately 4-6 kilobases, subdivided into three subfamilies, , and , and unassigned genus . Parvoviruses of aquatic animals infect crustaceans, mollusks, and finfish. This review describes these parvoviruses, which are highly host-specific and associated with mass morbidity and mortality in both farmed and wild aquatic animals.

Genomics of Re-Emergent in Atlantic Salmon Outbreaks.

Furunculosis, caused by , poses a significant threat to both salmonid and non-salmonid fish in diverse aquatic environments. This study explores the genomic intricacies of re-emergent outbreaks in Atlantic salmon (). Previous clinical cases have exhibited pathological characteristics, such as periorbital hemorrhages and gastrointestinal abnormalities.

Evolution and Current Status of Influenza A Virus in Chile: A Review.

The influenza A virus (IAV) poses a significant global threat to public health and food security. Particularly concerning is the avian influenza virus (AIV) subtype H5N1, which has spread from Europe to North and Central/South America. This review presents recent developments in IAV evolution in birds, mammals, and humans in Chile.

Continuous surveillance and viral discovery in animals and humans are a core component of a one-health approach to address recent viral reverse zoonoses.

Contemporary human and animal viruses have a broad or narrow host range-those with a broad host range are potentially transmitted from animals to humans (ie, zoonosis) or humans to animals (ie, reverse zoonosis). This Currents in One Health article reviews the recent reverse zoonoses involving Coronaviridae, Poxviridae, arboviruses, and, for nonhuman primate species, the human respiratory viruses. The prevention and control of reverse zoonoses are also reviewed.

A One Health approach to mitigate the impact of influenza A virus (IAV) reverse zoonosis is by vaccinating humans and susceptible farmed and pet animals.

The term reverse zoonosis specifically refers to the natural transmission of disease and infection from humans to animals, with humans as the reservoir host replicating the infectious agent. In the last 20 years, reverse zoonosis has increasingly garnered attention because of human disease outbreaks. In this Currents in One Health article, the author will review host range as the main risk factor for reverse zoonosis, with an emphasis on influenza A virus (IAV) disease events in humans and other species in the context of a "One Health" approach to gain a better understanding of their transmission routes to facilitate their control and prevent them from occurring.
