From the Guidelines
For a 3-year-old with fever and positive RSV, treatment is primarily supportive care focused on managing symptoms and ensuring adequate hydration. Give acetaminophen (Tylenol) at 10-15 mg/kg every 4-6 hours or ibuprofen (Motrin, Advil) at 5-10 mg/kg every 6-8 hours to reduce fever and discomfort, as recommended by the American Academy of Pediatrics 1. Ensure the child drinks plenty of fluids to prevent dehydration, offering small amounts frequently. Use saline nasal drops and gentle suctioning with a bulb syringe to clear nasal congestion. A cool-mist humidifier in the child's room can help ease breathing difficulties.
Key Considerations
- Monitor for warning signs requiring immediate medical attention, including difficulty breathing, bluish lips or face, severe dehydration (dry mouth, decreased urination, no tears when crying), or extreme lethargy.
- Most RSV infections resolve within 1-2 weeks as the virus runs its course.
- Antibiotics are not effective against RSV since it's a viral infection.
- The goal of treatment is to keep the child comfortable while their immune system fights the infection, with special attention to maintaining open airways and proper hydration, as outlined in the clinical practice guideline for the diagnosis, management, and prevention of bronchiolitis 1.
Prophylaxis Considerations
- Palivizumab prophylaxis is not recommended for children in the second year of life, except for those with specific conditions such as chronic lung disease of infancy who require supplemental oxygen, chronic corticosteroid therapy, or diuretic therapy within 6 months of the onset of the second RSV season 1.
- The use of palivizumab in the second year of life is generally not recommended due to the low risk of RSV hospitalization and the limited benefit of prophylaxis, as stated in the updated guidance for palivizumab prophylaxis among infants and young children at increased risk of hospitalization for respiratory syncytial virus infection 1.

From the Research
Treatment Options for RSV Infection
- For a 3-year-old child with fever and positive for RSV, the treatment options are limited. According to 2, the only FDA-approved drug for RSV is aerosolized ribavirin.
- However, 3 suggests that palivizumab, an RSV-specific monoclonal antibody, can reduce hospitalization due to RSV infection and may result in a large reduction in RSV infections.
- 4 mentions that palivizumab is a prophylactic drug given to high-risk infants, but it has a limited impact on annual hospitalization rates caused by RSV.
- 5 states that treatment of RSV LRTI has remained mostly supportive, i.e., hydration and oxygenation, and that palivizumab and ribavirin are the only options currently available for prevention and treatment of RSV infection.
- 6 recommends prophylaxis against RSV infections using palivizumab for children <2 years of age with chronic respiratory diseases and children <6 months old who were born before gestational week 26.
Considerations for Treatment
- The effectiveness of palivizumab in preventing severe RSV disease in children is supported by high certainty evidence, as shown in 3.
- The use of ribavirin inhalation treatment may be considered in high-risk infants with clinical symptoms indicating a serious course of an RSV infection, as stated in 6.
- Combination antiviral therapy may be explored in the future to overcome the emergence of RSV escape mutants, as mentioned in 5.
Age and Risk Factors
- The age and risk factors of the child, such as chronic respiratory diseases or premature birth, should be taken into account when considering treatment options, as recommended in 6.
- Palivizumab has been shown to be effective in reducing hospitalization due to RSV infection in high-risk infants, as demonstrated in 3.
