The lung tissue begins to swell and produce mucus, and the cells lining the bronchioles begin to slough off into the air passages. As the airways narrow from swelling, and mucus accumulation, breathing becomes difficult
death still occurs in 20-30% of cases, with a higher mortality rate of 50% in children less than 10 years old.
Photosysnthesis occurs in chloroplast. Light independent occurs at the stroma whereas light dependant occurs in the thylakoid.

The viruses that cause bronchiolitis spread very easily, making prevention difficult. Common sense measures such as frequent hand washing and keeping children away from crowds and sick individuals are only partially effective.
The majority of children who get bronchiolitis, even severe infections, recover without complications in one to two weeks, although fatigue and a light cough may linger longer. About 60% of people develop only cold-like symptoms.
RSV infection is also called bronchiolitis, because it is marked in young children by inflammation of the bronchioles.

Although there are alternative treatments for cold symptoms, such as echinacea and zinc, parents should consult their health practitioner about the appropriateness of using these treatments in very young children.
Bronchiolitis is usually diagnosed through a physical examination by a pediatrician or family physician. The physician often finds an increased heart rate, rapid, labored breathing, and crackles in the lungs when the child inhales.
Bronchitis in children is very different to bronchitis in adults. In children it is normally referred to as acute bronchitis or bronchiolitis (depending on if the larger bronchi or the smaller bronchioles are affected). In adults the condition is chronic (meaning long term and usually incurable), in children it is acute, meaning it is more sudden in onset and short lived (the child will usually make a full recovery within two weeks). The main symptoms of bronchiolitis are: * a dry cough * increased breathlessness * feeding difficulty (due to breathlessness) * More effort required for breathing * sometimes wheezing Bronchiolitis can vary greatly in severity, most will recover without treatment, however in some cases it can require hospitalisation if you are worried about your child take them to your GP as soon as possible. If they have any difficulty in breathing then call for an ambulance.
The most common signs of bronchiolitis involve the infant's struggle to breathe. The child may take 50-60 breaths per minute and may develop brief periods when they stop breathing (apnea) and begin to turn blue (cyanosis ).
