This list includes 17 Viruses that start with G, from “GB virus C” to “Guinea pig cytomegalovirus”. The entries cover human and animal viruses, including zoonotic and species-specific agents used in clinical and research contexts.

Viruses that start with G are viral species whose accepted names begin with the letter G. For example, GB virus C (human pegivirus) drew attention for possible effects on HIV progression.

Below you’ll find the table with Name, Classification, Affects humans?, Symptoms, Transmission, Notes, and References.

Name: The virus’s accepted and common names, so you can find and cross-reference the exact organism quickly.

Classification: Family, genus, and species per ICTV to help you understand related viruses and clinical relevance.

Affects humans?: Yes/No plus a short qualifier about zoonotic or opportunistic status, so you know human relevance.

Symptoms: Typical clinical presentations in concise terms (five to ten words) so you can recognize common disease patterns.

Transmission: Primary routes of spread listed succinctly, helping you assess infection risk and preventive measures.

Notes: Key context such as host range, research uses, or notable outbreaks to add useful background for you.

References: Citations to authoritative sources like ICTV, CDC, WHO, and PubMed for verification and further reading.

Descriptions

Gamboa virus
Mosquito-transmitted orthobunyavirus causing occasional febrile illness; symptoms fever, headache, myalgia, nausea, vomiting; reservoir mosquitoes/rodents. [ICTV]
Guaroa virus
Orthobunyavirus in South America that causes febrile disease; symptoms fever, headache, joint pain, rash, nausea; mosquito reservoir. [ICTV]
Guanarito virus
Causes Venezuelan hemorrhagic fever with fever, bleeding, gastrointestinal symptoms, shock, weakness; reservoir: cane mouse (rodent). [WHO]
GB virus C
Widespread human pegivirus (formerly “Hepatitis G”/GBV‑C); usually asymptomatic and not clearly disease-causing; common in blood exposures. [ICTV]
Getah virus
Alphavirus infecting horses and pigs; rare human infections with fever, rash, joint pain, malaise; transmitted by mosquitoes. [ICTV]
Gibbon ape leukemia virus
Gammaretrovirus causing leukemia in gibbons; used in research; reservoir captive gibbons; not a human pathogen. [ICTV]
Gibbon ape foamy virus
Foamy (spuma) virus of gibbons; typically causes no disease in hosts, rare human exposures documented; research interest. [ICTV]
Guinea pig cytomegalovirus
Betaherpesvirus infecting guinea pigs; causes CMV-like disease in animals and is a model for congenital CMV research. [ICTV]
Groundnut rosette virus
Virus complex causing severe rosette disease in peanuts: stunting, leaf chlorosis, yield loss; transmitted by aphids. [ICTV]
Grapevine fanleaf virus
Major grapevine pathogen causing leaf malformation, reduced yield and poor fruit; transmitted by nematodes and grafting. [ICTV]
Grapevine virus A
Common vitivirus in grapevines linked to vine decline and reduced productivity; spreads via grafting and insect vectors. [ICTV]
Grapevine virus B
Vitivirus found in grapevines, associated with reduced vigor and leaf discoloration; economic impact in vineyards. [ICTV]
Gouleako virus
Orthobunyavirus isolated from mosquitoes in West Africa; not known to cause human disease but monitored in vector studies. [PubMed]
Goatpox virus
Capripoxvirus causing pox lesions, fever and economic losses in goats; rare human infections documented. [ICTV]
Goose parvovirus
Parvovirus causing Derzsy’s disease in goslings with high mortality; important in poultry health and farming. [ICTV]
Grass carp reovirus
Reovirus infecting grass carp causing hemorrhagic disease in aquaculture; major economic impact in fisheries. [PubMed]
Giardia lamblia virus
Totivirus that infects Giardia intestinalis (parasite); studied for parasite biology, not a direct human pathogen. [ICTV]
