1-Bronchiolitis usually effects babies under 6 months of age, and is a common and sometimes serious illness. It is caused by a virus, most commonly RSV (Respiratory syncytial virus), which affects the small airways in the lungs. Bronchiolitis causes inflammation in the small airways making them swell and narrow. Bronchiolitis starts off like a cold over a period of 2 to 3 days, but can develop into respiratory distress with wheezing, a tight wheezy cough, and quickened breathing, symptoms similar to asthma. Sometimes babies have trouble feeding and they need to rest and drink little and often.2- No mentioned fever
