II. Epidemiology: RSV
-
Incidence
- Worldwide: 33 Million with 3.6 Million hospitalizations in 2019 (8.1 cases per 1000 per year)
- United States: 2.1 Million children under age 5 years seek medical attention for RSV annually
- Annual epidemics in U.S.
- Post-Covid (2020) RSV epidemics peaked in sping and summer
- Pre-covid RSV epidemics were in winter to early spring
- Range: November to April
- Peak: January to February
- Overall hospitalization rate
- U.S. 1-2% of children with RSV (57,000 per year, 2.9 cases per 1000)
- Youngest children are at highest risk for hospitalization (esp. age <90 days)
- RSV Bronchiolitis results in hospitalization of 2-3% of infants <12 months old
- Severe RSV Bronchiolitis requiring hospitalization occurs in 25 per 1000 infants age <30 days
- Attack rates
- Daycare exposure: 100% infection rate
- Sibling exposure: 40% infection rate
- Cohorts Affected
- Children under age 2 years (usually 1-6 months old)
- Of infants at risk, 50% will be infected
- By age 2 years, nearly all children will have had one RSV infection (at least 90%)
- Prior infection is no protection against future infection
- Older children and adults
- Common Cold-like Syndrome
- Rhinorrhea, Sore Throat, and cough
- Elderly (esp. age >75 years)
- Severe Pneumonia may result
- In U.S., >160,000 older adults are hospitalized, and 10,000 die of RSV per year
- Immunocompromised patients and significant comborbid conditions
- Diabetes Mellitus
- Chronic Lung disease (e.g. copd)
- Chronic Kidney Disease
- Cardiovascular disease
III. Risk Factors: More Severe Course
- Young infants (esp. age <90 days)
- Prematurity
- Passive Smoke Exposure
- Complex Congenital Heart Disease
- Chronic lung disease
- Immunosuppression
- Neuromuscular disease
- Metabolic disorder
- Staat (2002) Semin Respir Infect 17:15-20 [PubMed]
IV. Pathophysiology: RSV
- Enveloped, nonsegmented, negative-strand RNA virus (Paramyxoviridae Family)
- Subtypes A (causes more severe disease)
- Subtypes B
- Transmission
- Close contact
- Fingers or fomites
- Self inoculation of Conjunctiva or anterior nares
- Coarse aerosols from coughing or sneezing
- Viral load peaks at 4 to 5 days
- Corresponds to peak illness severity at 3-5 days
- Incubation: 2 to 6 days (up to 8 days)
- Virus shedding: 3 to 8 days (up to 4 weeks in infants)
- Duration of illness (under age 2 years)
- Re-infection with different RSV forms is common
- Prior RSV infection confers no Immunity against new infection
- Infectious course
- Viral replication starts in the nasopharynx
- Spreads to the small Bronchiole epithelial lining
- Results in small airway obstruction, air trapping and increased airway resistance
- Lower respiratory tract infection onset within 3 days
- Increased airway edema and mucous production
- Ultimately tissue necrosis
V. Causes: Bronchiolitis
- Respiratory Syncytial Virus (RSV)
- Responsible for 50-80% of cases
- Coninfection with other virus (e.g Rhinovirus) in up to 55% (up to 30% of hospitalized RSV cases)
- Human Metapneumovirus (MPV)
- Emerging paramyxovirus
- Similar presentation as RSV
- Hamelin (2004) Clin Infect Dis 38:983-90 [PubMed]
- Parainfluenza
- Rhinovirus
- Influenza
- Adenovirus
- Human Bocavirus
VI. Symptoms
- Viral prodrome (initial 2-3 days)
- Typical symptoms in infants and young children
- Cough (98%)
- Low grade fever (75%)
- Labored breathing (73%)
- Wheezing (65%)
- Rhinorrhea
- Mild systemic symptoms
- Typical symptoms in older children
- Severe illness
- Grunting
- Nasal flaring
- Intercostal retractions
- Tachypnea or Dyspnea
- Hypoxia and Cyanosis
- Apparent Life Threatening Event or Apnea
- Premature Infants or very young infants are at increased risk
- May occur without other signs of respiratory distress
VII. Signs
- See Clinical Severity Scoring System Tool
- Respiratory
- Common findings
- Diffuse Wheezing
- Rales
- Other findings
- Respiratory distress or Respiratory Failure
- Accessory Muscle use (e.g. Intercostal retractions)
- Grunting
- Hypoxia (Oxygen Saturation <92%)
- Cyanosis
- Common findings
- Hydration
- Assess for Dehydration (mucous membranes, alertness, Skin Turgor, decreased Urine Output)
VIII. Differential Diagnosis
- See Wheezing
- Reactive airway disease
- Foreign Body Aspiration
- High fever suggests alternative diagnosis (e.g. Pneumonia)
- Especially consider in unimmunized children
IX. Evaluation: Age under 3 months
- Infants under age 30 days
- Complete full Neonatal Sepsis evaluation for febrile infants under 1 month of age (despite Bronchiolitis diagnosis)
- Infants under age 60 days
- Evaluation based on clinical evaluation
- Consider admission of infants <6 to 8 weeks of age with Bronchiolitis due to apnea risk
- Infants ages 60-90 days of age
- Ill appearing, febrile infants should be evaluated for bacteremia (and coinfection)
- Non-toxic febrile infants at 60-90 days with Bronchiolitis do not need a bacteremia work-up
- Blood Cultures and Lumbar Puncture are not needed
- Urinalysis and Urine Culture should still be performed
- Ralston (2011) Arch Pediatr Adolesc Med 165(10):951-6 [PubMed]
X. Labs
-
Blood Culture indications
- Not needed in routine cases
- Consider in toxic appearing children, fever >38.5 C (101.3 F) or ICU admission
- Complete Blood Count (CBC) is not routinely recommended
-
Venous Blood Gas (VBG) Indications
- Children who appear to be tiring
- Severe respiratory distress
- FIO2 requirements >40%
- RSV swabs or washings of nasopharynx, throat, or Sputum
- Precautions
- RSV is a clinical diagnosis based on symptoms and signs (see above)
- Routine testing is not recommended for confirmation
- RSV is only one cause of Bronchiolitis (e.g. MPV, parainfluenza, Influenza, Adenovirus, bocavirus)
- A negative RSV does not exclude other Bronchiolitis cause
- Indications
- Febrile infants <3 months of age (evaluate for Neonatal Sepsis)
- Immunocompromised children
- Intensive Care Unit Admission
- Other diagnosis considered (e.g. Sepsis in age under 2-3 months)
- RSV positive puts a child at very low risk of serious Bacterial Infection
- However coninfection with other viruses is common (up to 55% of cases)
- Levine (2004) Pediatrics 113(6): 1728-34 [PubMed]
- Inpatient room placement (shared inpatient rooms)
- Consider grouping patients with similar symptoms instead of basing on lab criteria
- Epidemiologic data to define start of outbreak
- Efficacy
- LAMP NAAT or PCR
- Test Sensitivity: 91 to 97% (LR- 0.03 to 0.09)

- Precautions
-
Urinalysis and Urine Culture
- Consider in patients with RSV severe enough to consider admission
- Urinary Tract Infections are present in 2-5% of RSV cases
- However this is similar to baseline UTI rate in asymptomatic children
- Urinalysis is controversial in febrile children with Bronchiolitis (some guidelines recommend)
- RSV is associated with a decreased risk of other conditions
- Decreased risk of Meningitis
- Decreased risk of bacteremia
XI. Imaging: Chest XRay
- Indications
- Not routinely recommended in Bronchiolitis (very low yield)
- Chest XRay risks False Positives (e.g. Pneumonia) and Antibiotics overuse
- High fever
- Hypoxemia (Oxygen Saturation <90%)
- Severe symptoms (e.g. ICU admission)
- Comorbid cardiopulmonary disease
- Respiratory complications (e.g. Pneumonia, Pneumothorax)
- Not routinely recommended in Bronchiolitis (very low yield)
- Findings consistent with Bronchiolitis
- Hyperexpansion or hyperinflation
- Peribronchial thickening or peribronchial markings
- Atelectasis
- Variable infiltrates or Viral Pneumonia
- May lead to False PositivePneumonia diagnoses (and unnecessary Antibiotics)
XII. Evaluation: Hospitalization Indications
- Place in respiratory isolation if admitted
- Central Apnea risk (1 to 24% of newborns with RSV)
- Witnessed apneic event
- RSV in infant under 6-8 weeks of age or birth weight <2.5 kg

- Respiratory distress
- See Clinical Severity Scoring System Tool
- See Respiratory Distress in Children with Pneumonia
- See Pediatric Early Warning Score (PEWS Score)
- Respiratory Rate (RR) consistenly >40 breaths per minute
- Oxygen Saturation <90%
- Brief minor desaturations are common with sleeping and eating
- Transient Hypoxia does not contraindicate disposition home in children with otherwise reassuring findings
- Principi (2016) JAMA Pediatr 170(6):602-8 +PMID:26928704 [PubMed]
- Retractions (intercostal, supraclavicular, abdominal)
- Grunting
- Lethargy
- Hypercarbia
- Chest XRay changes (e.g. Atelectasis)
- Cyanosis
XIII. Management: Effective Measures
-
General Measures
- Constantly reassess for signs of impending Respiratory Failure
- May be signaled by a 'normalization' of the Respiratory Rate (due to respiratory muscle Fatigue)
- Humidified Oxygen to keep Oxygen Saturation >90% (>88% while asleep)
- Low threshold to transition to Humidified High Flow Nasal Cannula as needed (see below)
- In practice, humidified High Flow Nasal Cannula (HHFNC) is typically used instead
- Suctioning of secretions
- Paramount intervention both during the acute evaluation and for home
- Especially for the obligate nose breathers age <2 years
- Includes gentle Nasal Saline with suctioning (avoid Trauma and secondary edema)
- Provide parents with a hospital-grade nasal suction bulb
- Acorn manual nasal aspirator
- NoseFrida
- Avoid frequent deeper, nasopharyngeal suctioning (via nose into posterior pharynx and upper airways)
- Excessive deeper nasopharygeal suctioning increases airway irritation
- In hospital setting, twice daily nasopharyngeal suctioning is sufficient
- Contrast with frequent nasal suctioning (e.g. NoseFrida, acorn) which is a mainstay of treatment
- Consider nasal Decongestant (Neo-Synephrine)
- Neo-Synephrine (Phenylephrine) is preferred (If a nasal Decongestant is used in children)
- Avoid afrin (Oxymetazoline) in children
- Risk of Central alpha-2 Agonist, Clonidine-like CNS depression ("One Pill Can Kill" list)
- Paramount intervention both during the acute evaluation and for home
- Hydration and frequent feedings
- Parents should anticipate smaller volume feedings more frequently (every 3-4 hours) for the first 5 days of RSV
- Feedings should continue on High Flow Nasal Cannula
- If child is unable to take oral feedings, then consider Feeding Tube for Enteral Nutrition
- Constantly reassess for signs of impending Respiratory Failure
- Severe cases
- Humidified High Flow Nasal Cannula (HHFNC)
- Indicated in increased Work of Breathing (e.g. retractions, grunting, apnea, nasal flaring) or Hypoxia
- Humidified High Flow Nasal Cannula starting at 1.5 to 2 L/kg/min and titrate as needed
- See Humidified High Flow Nasal Cannula for protocol
- Required rates above 2 L/kg/min are considered more severe (and typically admitted to PICU instead of ward)
- Efficacy
- Prevents airway collapse and Atelectasis
- Decreases work of breathing
- Effective and well tolerated
- Nasal continuous positive airway pressure (nasal CPAP or nCPAP) or RAM Cannula
- Alternative to Humidified High Flow Nasal Cannula
- Offers greater PEEP than HHFNC
- Endotracheal Intubation with Mechanical Ventilation
- Helium-Oxygen therapy
- Humidified High Flow Nasal Cannula (HHFNC)
XIV. Management: Ineffective or Inconsistently Effective Measures
- Nebulizer (not recommended as of 2014, per AAP)
- Precautions: AAP 2014 Guidelines
- AAP recommends no nebulizer treatments (including Albuterol, Epinephrine and Hypertonic Saline)
- AAP recommends no Corticosteroids
- Supplemental Oxygen is optional when Oxygen Saturations are >90%
- http://pediatrics.aappublications.org/content/134/5/e1474
- Nebulized Albuterol
- Albuterol is often trialed in the Emergency Department in moderate to severe cases (see below)
- AAP guidelines may reflect an RSV-specific lack of response to Bronchodilators
- However, undifferentiated Bronchiolitis symptoms (esp. with RAD, atopy) may respond
- Background per AAP
- Albuterol does not improve oxygenation in RSV
- Albuterol does not shorten hospital stay in RSV
- Albuterol may offer minor symptomatic relief in RSV
- Albuterol has adverse effects (e.g. Tachycardia)
- Older approach (prior to 2014 guidelines)
- May be effective in up to 50% of RSV patients (especially for children with history of Asthma or atopy)
- May still give a trial if atopic/RAD history or Warm Respiratory Scoring Tool >4
- If improvement with trial then continue every 6 hours (if not, then supportive care only)
- References
- Albuterol is often trialed in the Emergency Department in moderate to severe cases (see below)
- Nebulized Atrovent
- See Reactive Airway Disease
- Some evidence as of 2011 suggesting Atrovent is effective (but not recommended by AAP 2014 Guidelines)
- Nebulized racemic epinephrine
- Not recommended by AAP 2014 Guidelines
- Variable efficacy and use has declined since 2007
- Requires 2-4 hours of observation after administration due to transient effect with risk of rebound
- Wainright (2003) N Engl J Med 349:27-35 [PubMed]
- Hypertonic Saline Nebulization (not recommended)
- Not recommended by AAP 2014 Guidelines for acute use (ED and short 1-2 day hospitalizations)
- Nebulizer dose: 4 ml of 3% Hypertonic Saline
- May shorten hospital stay (from >3 days)
- Increases cough
- Not effective in preventing hospitalization (may not be as useful for emergency care)

- Precautions: AAP 2014 Guidelines
-
Systemic Corticosteroids (not recommended)
- Corticosteroids do not decrease severity of illness or shorten the disease course
- Corticosteroids are not recommended for RSV Bronchiolitis by American Academy of Pediatrics
- Atopic Patients and older patient's with Asthma may benefit
- Data is mixed and some studies have shown benefit (e.g. Systemic Dexamethasone with Nebulized Epinephrine)
- Some studies have shown benefit with decreased length of hospital stay (especially children under age 1 year old)
XV. Management: Emergency Department Approach
- Attempt to determine disposition (hospitalization versus home) in the first hour
- Step 1: Supplemental Oxygen to maintain Oxygen Saturation >90%
- Step 2: Nasal Suctioning
- Assess patient (consider using a scoring system)
- Nasal Saline and suction
- Consider nasal Decongestant (Neo-Synephrine) as described above (avoid afrin)
- Assess patient (consider using a scoring system)
- Step 3: Nebulized Albuterol or Albuterol MDI with Aerochamber and mask
- Not recommended by AAP as of 2014 but often trialed in Emergency Department
- Cases in which Albuterol may have better efficacy
- Atopy (Eczema, Family History of Asthma) or reactive airway disease history
- Warm Respiratory Scoring Tool >4
- Older infants over age 6 months with rhinovirus Bronchiolitis
- Viral Bronchiolitis during non-RSV peak times
- Bronchiolitis chiefly presenting with Wheezing and subcostal retractions
- Nino (2020) ERJ Open Res 6(4): 00135-2020 +PMID:33083437 [PubMed]
- Supply family with Albuterol for home if effective
- Consider Dexamethasone (or other Corticosteroid) in those who respond to Albuterol (or have atopic/RAD risks)
- Also not recommended by AAP as of 2014
- Step 4: High Flow Nasal Cannula (HHFNC)
- Indicated in increased Work of Breathing (e.g. retractions, grunting, apnea, nasal flaring)
- Associated with decreased hospital stay and need for treatment escalation in age <24 months

Definition (MEDLINEPLUS) |
Respiratory syncytial virus (RSV) causes mild, cold-like symptoms in adults and older healthy children. It can cause serious problems in young babies, including pneumonia and severe breathing problems. Premature babies and those with other health problems have the highest risk. A child with RSV may have a fever, stuffy nose, cough, and trouble breathing. Lab tests can tell if your child has the virus. There is no specific treatment. You should give your child fluids to prevent dehydration. If needed, you can also give a pain reliever (not aspirin) for fever and headache. RSV easily spreads from person to person. You can get it from direct contact with someone who has it or it by touching infected objects such as toys or surfaces such as countertops. Washing your hands often and not sharing eating and drinking utensils are simple ways to help prevent the spread of RSV infection. There is currently no vaccine for RSV.
