Honey bee infected with deformed wing virus. Arthropods is the largest group of animals and has shown to be a major reservoir of different viruses, both insect-specific viruses (ISV) and viruses that can infect both vertebrates and invertebrates, more known as arthropod-borne viruses (arboviruses).
The virus causes a lethal haemorraghic disease in domestic pigs. Some strains can cause death of animals within as little as a week after infection. In other species, the virus causes no obvious disease. ASFV is endemic to sub-Saharan Africa and exists in the wild through a cycle of infection between ticks and wild pigs, bushpigs and warthogs.

Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera.[3] 14 species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.

A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [ 1 ] Examples are the common cold , gastroenteritis and pneumonia .
Both viruses are contagious, highly virulent, and capable of infecting a number of mammalian species and causing potentially fatal disease. Due to the lack of either a licensed human vaccine (a Hendra virus vaccine exists for horses) or antiviral therapies, Hendra virus and Nipah virus are designated as Biosafety level (BSL) 4 agents. The ...
Toroviruses, Coronaviruses and arteriviruses are in the order Nidovirales, a group of non segmented, positive sense single stranded animal viruses. [35] Despite the differences in their genome size, varying host range and their replication strategies, the similarities in the sequence identities of the replicase proteins among different species ...
