most commonly found in children - upper respiratory tract no current vaccine available, but palivizumab (virus-fighting anitibodies against RSV) fights against diseases caused by RSV, such as pneumonia and bronchiolitis - occurs within 3-4 months during fall, winter, or early spring seasons
- mostly occurs in US, but varies by region mostly occurs before the age of 2 and even in adults before the age of 65 - when children are exposed to the virus for the first time, about 25-40% of them will express symptoms of bronchiolitis and/or pneumonia
- o.5-2.5% of these will need to visit the hospital (>6 mnths of age) - children infected with RSV show symptoms between 4 to 6 days of infection
- most children will recover within 2 weeks
- children with weaker immune systems -> 1-3 weeks each year, there are about 75,000 to 12,500 children that are hospitalized due to this infection normal symptoms
-runny nose
-decrease in appetite
-wheezing young infants
-decreased activity
-breathing difficulties visits to hospital/clinician are very common; check for severity of disease in severe cases, child will be hospitalized
- will require supplemental oxygen
- suctioning of mucus from lungs
- intubation with mechanical ventilation children at risk:
- premature babies
- >2 y.o.a with congenital heart or chronic lung disease
- children with immunocompromised body systems In adults, could just be:
- stuffy/runny nose
- sore throat
- mild headache
- cough
- fever
- general flu symptoms - droplets through coughing and sneezing
- child gets it when inhaling those particles; particles contact with nose, eye, or mouth Direct Contact:
> kissing child on the face
> coughing
> sneezing Indirect Contact:
> touching an infected surface, such as table, crib, desk
> rubbing eye, nose after touching infected surface Nasal/oral secretions - Frequent handwashing
- wiping off surfaces with either soap/water or disinfectant - Do not share cups/utensils with others
- cover mouth when coughing or sneezing Palivizumab - drug available to prevent severe cases of RSV symptoms

No vaccines available as of yet can be identified by a nasal/oral swab, suctioned through bulb syringe allow plenty of time for recovery; can use cool-mist vaporizers during cold, winter months Risks of getting RSV:
-attending day care
-being exposed to tobacco smoke
-having school-aged children
-living in crowded conditions other symptoms include :
- cyanosis (blueness of skin)
- breathing difficulty
- (croupy) cough
- fever
- nasal flaring
- rapid breathing
- shortness of breath
- stuffy nose
- wheezing If not treated immediately, may cause:
- Croup
- bronchiolitis
- ear infections
- lung failure
- pneumonia
