From the Guidelines
Treatment of rotavirus primarily focuses on managing symptoms and preventing dehydration, as there is no specific antiviral medication to eliminate the virus. The cornerstone of treatment is oral rehydration therapy (ORT), using solutions like Pedialyte, Infalyte, or WHO-formulated oral rehydration salts to replace lost fluids and electrolytes, as recommended by studies such as 1. For mild to moderate dehydration, give 50-100 mL/kg of ORT over 3-4 hours, then continue with maintenance fluids. Severe dehydration requires immediate medical attention and possibly intravenous fluids. Some key points to consider in the treatment of rotavirus include:
- Continue normal feeding during illness, avoiding dairy products temporarily if they worsen diarrhea, as suggested by 1.
- Zinc supplementation (10-20 mg daily for 10-14 days) can reduce symptom severity and duration.
- Antipyretics like acetaminophen (10-15 mg/kg every 4-6 hours) can manage fever.
- Avoid antimotility medications in children as they can worsen complications.
- Probiotics such as Lactobacillus GG or Saccharomyces boulardii may help reduce symptom duration. Prevention through rotavirus vaccination is highly effective and recommended for infants, as stated in studies such as 1, 1, and 1. Rotavirus is highly contagious, so practice good hand hygiene and disinfect contaminated surfaces to prevent spread. Most cases resolve within 3-8 days with proper supportive care as the immune system clears the infection naturally, as described in 1. It's essential to prioritize prevention and treatment strategies that minimize morbidity, mortality, and improve quality of life, as emphasized by the need for vaccination and proper hygiene practices 1.
From the Research
Treatment Options
- The primary treatment for rotavirus infection is supportive and focused on replacing fluid and electrolyte losses, with oral or intravenous rehydration being the main approach 2, 3, 4.
- No antiviral therapies are currently available for the treatment of rotavirus infection 2, 3, 4.
- Recently, therapies such as probiotics have been developed as adjuncts to rehydration therapy 4.
- Ondansetron, a serotonin receptor antagonist, has been shown to reduce rotavirus symptoms, including vomiting and diarrhea, in a randomized double-blinded placebo-controlled trial 5.
Role of Vaccination
- Vaccination is considered the primary public health intervention for rotavirus infection, with current vaccines (e.g. RotaTeq and Rotarix) being effective in reducing rotaviral gastroenteritis, emergency department visits, and hospitalizations 3, 4.
- Rotavirus vaccination is now included as part of the routine vaccination schedule for all infants in the United States 3.
- The introduction of rotavirus vaccines has led to dramatic drops in severe rotavirus-related hospitalizations and has reduced emergency room visits, with herd immunity also being noted 4.
Diagnostic and Therapeutic Considerations
- Diagnostic confirmation of rotaviral gastroenteritis requires laboratory tests, but these are not always performed due to cost and the fact that specific diagnosis does not affect treatment 3.
- Clinicians caring for adults with gastroenteritis should consider rotavirus in the differential diagnosis, particularly in immunocompromised adults who can experience severe and sustained infection 6.
- Supportive care is the primary approach for adults with suspected rotavirus infection, as symptoms are generally self-limiting 6.
