This list includes 4 Viruses that start with Y, from “Yaba monkey tumor virus” to “Yokose virus”. Several are zoonotic or primarily animal viruses studied in research and diagnostics.

Viruses that start with Y are viruses whose commonly used names begin with the letter Y. A notable example is Yaba monkey tumor virus, historically important in early tumor virology.

Below you’ll find the table with Virus name, Classification, Affects humans?, Symptoms, Transmission.

Virus name: The common and scientific names used to identify each virus, so you can recognize and search for them quickly.

Classification: Family and genus per ICTV, giving you taxonomic context and helping compare related viruses.

Affects humans?: States “Yes” or “No” with a short qualifier so you know human relevance at a glance.

Symptoms: Lists typical clinical presentations in five to ten words so you can spot common disease features quickly.

Transmission: Summarizes the main transmission routes concisely so you can assess spread and prevention priorities.

Descriptions

Yellow fever virus
Acute mosquito‑borne illness causing fever, jaundice and sometimes hemorrhage; infects humans and nonhuman primates in tropical Africa and South America; vaccine‑preventable but still causes outbreaks and deaths.
Yellow head virus
Highly virulent pathogen of farmed shrimp causing yellowed head, lethargy and rapid, high mortality; important in Asian aquaculture; not known to infect humans.
Yaba monkey tumor virus
Poxvirus that causes benign skin tumors in monkeys; occasionally transmits to humans producing mild, self-limited skin nodules; first described in West Africa and linked to laboratory exposures.
Yokose virus
Flavivirus isolated from bats in Japan/Asia; no confirmed human disease to date but monitored for spillover potential; natural cycle and symptoms in humans remain unestablished.
