ANATOMY

Detailed explanation-1: -The term NCDs refers to a group of conditions that are not mainly caused by an acute infection, result in long-term health consequences and often create a need for long-term treatment and care. These conditions include cancers, cardiovascular disease, diabetes and chronic lung illnesses.

Detailed explanation-2: -Asthma is a chronic (long-term) condition that affects the airways in the lungs. The airways are tubes that carry air in and out of your lungs. If you have asthma, the airways can become inflamed and narrowed at times. This makes it harder for air to flow out of your airways when you breathe out.

Detailed explanation-3: -The two most common chronic respiratory diseases are asthma and chronic obstructive pulmonary disease (COPD). These both affect the airways in the lungs. Asthma is characterized by recurrent attacks of breathlessness and wheezing due to airway narrowing, which vary in severity and frequency from person to person.

Detailed explanation-4: -Viral infections such as respiratory syncytial virus (RSV) and human rhinovirus (hRV) have been implicated in asthma exacerbation in children because of their ability to cause severe airway inflammation and wheezing.
