This list includes 11 Viruses that start with V that begin with V, from “Vaccinia virus” to “Visna virus”. Many entries are notable human pathogens or zoonotic viruses with historical or veterinary importance.

Viruses that start with V are viruses named with the letter V and include human or animal pathogens. Vaccinia virus, notably, enabled smallpox vaccination and later served in vaccine research and biotechnology.

Below you’ll find the table with Virus, Classification (family/genus/species), Affects humans?, Common symptoms, Transmission, and Notes/Sources.

Virus: The common or accepted name of each virus to help you quickly identify the pathogen you are researching.

Classification (family/genus/species): Shows ICTV family, genus and species so you can place the virus in standard taxonomy and compare related viruses.

Affects humans?: Indicates whether the virus infects people, with a short qualifier like “zoonotic” or “opportunistic” for context.

Common symptoms: Lists the typical clinical features in plain terms so you can recognize common presentations.

Transmission: Summarizes the principal transmission routes succinctly so you can understand how infection spreads and risks.

Notes/Sources: Provides brief context, notable facts, and primary references like ICTV, CDC or WHO for further reading.

Descriptions

Varicella-zoster virus
Causes chickenpox and shingles; transmits by respiratory droplets and direct contact; humans are the primary host.
Variola virus
Cause of smallpox, eradicated globally; transmitted by respiratory droplets and prolonged contact between humans.
Vaccinia virus
Orthopoxvirus used in smallpox vaccines; can infect humans via inoculation or contact and occasionally animals.
Vesicular stomatitis Indiana virus
Causes vesicular disease in livestock; transmitted by insect vectors, direct contact, and fomites; humans rarely infected by contact.
Vesicular stomatitis New Jersey virus
Related VSV serotype causing livestock vesicular disease; spread by biting insects and contact; rare mild human cases from exposure.
Venezuelan equine encephalitis virus
Mosquito-borne alphavirus causing encephalitis in horses and humans; transmitted by mosquitoes, with rodents as important reservoirs.
Variegated squirrel bornavirus 1
Zoonotic bornavirus linked to fatal human encephalitis from infected squirrels; likely transmitted by direct contact or bites from squirrels.
Visna virus
Sheep lentivirus causing chronic wasting, respiratory and neurologic disease; transmitted via respiratory secretions and milk; not a human pathogen.
Vesicular exanthema of swine virus
Marine mammal and swine calicivirus causing vesicular disease; spread by contact and contaminated meat; humans are not typically affected.
Viral hemorrhagic septicemia virus
Fish rhabdovirus causing mass die-offs in freshwater and marine fish; transmits via waterborne exposure and contact; not known to infect humans.
Viral nervous necrosis virus
Betanodavirus causing nervous necrosis in marine and farmed fish; spreads horizontally in water and via infected broodstock; not a human pathogen.
