Written by Medicover Team and Medically Reviewed by Dr Neha Mukhi , Pediatricians
Rotavirus is a highly contagious viral infection that mainly affects the intestines and causes severe diarrhea, especially in young children. It can lead to dehydration if not managed early. Understanding its signs, causes, and treatment is key to maintaining gut health and avoiding complications.
What are the Symptoms of Rotavirus?
Rotavirus symptoms usually start suddenly and can range from mild to severe, especially in babies and young children. Early recognition is important to manage the illness and avoid dehydration or serious complications.
Common Symptoms:
- Watery diarrhea that happens multiple times a day
- Nausea
- Frequent vomiting, which may lead to quick fluid loss
- Low-grade fever that may make the child feel weak
- Abdominal pain and stomach cramps
- Loss of appetite or refusing food and fluids
Severe Symptoms:
- Signs of dehydration such as dry mouth, sunken eyes, or very little urine output
- High fever that does not reduce easily
- Severe tiredness, excessive sleepiness, or unusual irritability
- Constant vomiting that prevents keeping fluids down
What are the Common Causes and Risk Factors of Rotavirus?
Rotavirus mainly spreads when someone touches contaminated hands, surfaces, water, or food.
It is highly contagious, especially in crowded places like daycares and schools where children often play close together.
Rotavirus Causes
- Direct infection with the rotavirus
- Poor hygiene, such as not washing hands after using the toilet
- Eating or drinking contaminated food or water
Risk Factors of Rotavirus
- Children under 5 years, especially infants
- Weak immune systems that can't fight infections well
- Living in crowded or unclean environments
- Not receiving the rotavirus vaccine
Good hygiene and timely vaccination are key steps in lowering the chance of infection.

Get Second OpinionHow Rotavirus is Diagnosed?
Doctors diagnose rotavirus mainly by checking symptoms and confirming it with a stool test that detects the virus.
Common Diagnostic Tests Include
- Stool antigen test, which is the most reliable method to detect rotavirus
- Physical examination to check signs of dehydration such as dry skin or weak pulse
- Electrolyte test to see if important minerals and fluids are imbalanced
Our pediatric and gastro teams work together to diagnose rotavirus accurately and provide personalized care for each child.
What are the Treatment Options for Rotavirus?
There is no specific medicine to kill rotavirus directly. Treatment focuses on managing symptoms and preventing dehydration, which is the most dangerous complication.
Primary Treatment Approaches
- Giving oral rehydration solutions (ORS) to replace lost fluids and minerals
- Providing zinc supplements to help shorten the duration and severity of diarrhea
- Using intravenous (IV) fluids in severe cases when oral intake is not possible
- Giving fever-reducing medicines like paracetamol under medical supervision
Recovery Timeline: Most children begin to improve within 3 to 8 days. The main focus during this period is to keep them hydrated and monitor for any warning signs.
When to See a Doctor Rotavirus?
Immediate medical attention is needed if your child shows any of the following signs:
- Diarrhea lasting longer than 48 hours
- No urination for many hours, dry lips, or sunken eyes, indicating dehydration
- Excessive sleepiness, extreme weakness, or unresponsiveness
Babies and young children are at higher risk of severe dehydration, so never delay seeking medical care in these situations.

What is the Recovery Process After Rotavirus Treatment?
Once the acute illness passes, children need time to regain their normal strength. Careful nutrition and hydration help the digestive system recover fully and prevent further problems.
Diet & Lifestyle Tips
- Start with soft, easy-to-digest foods like rice, bananas, and toast
- Avoid sugary, fried, or spicy foods that can irritate the stomach
- Keep giving plenty of fluids to maintain hydration
Providing families with clear guidance on diet, hydration, and signs to watch for after treatment, ensuring safe and smooth recovery at home.
How to Prevent Rotavirus?
Rotavirus spreads easily through contaminated hands, surfaces, food, or water, especially among infants and young children. While good hygiene is helpful, the most effective way to prevent rotavirus infection is through timely vaccination.
Prevention Tips
- Get infants vaccinated according to the schedule to build strong protection
- Wash hands with soap after using the toilet or handling diapers
- Clean and disinfect toys, high chairs, and other frequently touched surfaces
- Drink only safe, clean water to avoid contamination
Rotavirus Complications if Untreated
- Severe dehydration, which can lead to hospitalization
- Kidney function problems from prolonged fluid loss
- Electrolyte imbalance, affecting heart and muscle function
- Risk of serious illness requiring intensive care
Rotavirus Vaccine
The rotavirus vaccine is the most reliable way to protect infants from rotavirus infection, which commonly causes severe diarrhea in young children. It is an oral vaccine given during early infancy and is part of the routine immunization schedule.
Route and Dosage
- Rotarix: Given in 2 oral doses first at 6 weeks, second at least 4 weeks later, before 24 weeks of age. Each dose is 1 ml.
- RotaTeq: Given in 3 oral doses first between 6-12 weeks, followed by doses every 4-10 weeks. Final dose should be before 32 weeks of age. Each dose is 2 ml.
The vaccine is highly effective in preventing severe rotavirus-related diarrhea, with studies showing a protection rate of 85% to 98%.
Timely vaccination offers strong immunity and helps reduce hospitalizations in infants and young children.
Following preventive measures and seeking timely medical care are the best ways to keep children safe from rotavirus-related complications.
