Answer

Rubella virus is the sole member of the Rubivirus genus (Togaviridae family) and is a single-stranded RNA virus. Rubella virus naturally infects humans, primarily women, and is transmitted via nasopharyngeal secretions, with a peak incidence in late winter and spring. Approximately 50-75% of rubella virus infections are symptomatic; the rest are subclinical.
