Rotavirus
Viral gastroenteritis
The short answer
Rotavirus causes vomiting and watery diarrhoea, particularly in infants and young children. Dehydration is central to illness severity.
Transmission and timing
Virus shed in stool can reach the mouth through hands, surfaces or food. Transmission can occur before symptoms and after recovery.
CDC ↗Symptoms and risk groups
Vomiting, watery diarrhoea, fever and abdominal pain may occur. Reduced urination, fewer tears and unusual drowsiness can indicate dehydration.
CDC ↗When to seek help
Do not delay assessment if a baby cannot drink, is unusually inactive or may be severely dehydrated. Severe cases may require intravenous fluids.
CDC ↗For life-threatening symptoms, severe breathing difficulty or altered consciousness, call your local emergency number (112 in Türkiye).
What does the test show?
Stool testing can detect antigen or genetic material. A positive result does not measure dehydration; clinical assessment remains separate.
CDC ↗Care and treatment approach
Care centres on fluid and electrolyte replacement rather than a specific antiviral. Antibiotics do not treat rotavirus.
CDC ↗Prevention and everyday life
Vaccination reduces severe disease; hygiene matters but is not sufficient alone. Vaccinated children can still be infected. Check local schedules for products and age limits.
CDC ↗Clinical assessment note
Document intake, urine output and general condition in the monitoring plan. Record vaccination history and explain when the caregiver should seek reassessment.
CDC ↗Bring a question to your appointment
How should we replace fluids, and when should we seek reassessment?
