This list includes 31 Viruses that start with B, from “B virus” to “Bwamba virus”. These viruses vary from common human pathogens to zoonotic agents and are studied in diagnosis, treatment, and surveillance.
Viruses that start with B are a diverse group of pathogens found in humans, animals, and plants. Notable examples include Borna disease virus, historically linked to neurological outbreaks in horses and studied since the early 20th century.
