Question

Which disease can be fatal in children and why it is so?​

Answer 1

Answer:

Pneumonia. Pneumonia, usually caused by a bacterial infection, is a disease in which the air sacs in the lungs become inflamed and fill up with fluid. Although pneumonia is potentially fatal in all age groups, worldwide it kills more children under five than any other disease

Answer 2

Answer:

RSV

Respiratory syncytial virus (RSV) is an infection of the airways. It usually isn’t serious, but if your child is under 2, or has a heart or lung disease or a weak immune system, it can inflame the lungs and cause pneumonia.

"It's the most common viral respiratory infection that causes hospitalization in young babies," says Kathryn M. Edwards, MD, director of the Vanderbilt Vaccine Research Program.
