5 Must Know Facts For Your Next Test

  1. Reoviridae includes Rotavirus, a leading cause of severe diarrhea in infants and young children worldwide.
  2. The viral genome consists of 10-12 segments of double-stranded RNA, allowing for genetic reassortment.
  3. Transmission primarily occurs through the fecal-oral route, often via contaminated water or food.
  4. Rotavirus vaccines have significantly reduced the incidence of severe gastroenteritis in vaccinated populations.
  5. Symptoms typically include vomiting, watery diarrhea, fever, and abdominal pain.
