Final answer:
Respiratory infections in children are most frequently caused by viruses, with the common cold, flu, and RSV being typical examples. These infections spread through respiratory droplets and are mostly self-limiting.
Step-by-step explanation:
Most respiratory infections in children are caused by viruses. These viral infections are typically more frequent and less severe than those caused by bacteria. Conditions like the common cold, influenza (flu), and respiratory syncytial virus (RSV) are all viral in nature. Respiratory diseases are often transmitted through droplets when a person coughs or sneezes, and viruses like the ones causing colds, flu, and RSV can spread easily from person to person via these respiratory droplets. While bacterial respiratory diseases can be treated with antibiotics, viral infections generally do not have specific treatments and are often self-limiting, resolving on their own with supportive care.
Respiratory tract infections in children are most commonly caused by viruses. Viral respiratory infections, such as the common cold and influenza, are more frequent than bacterial infections. These viral infections often lead to mild symptoms and are self-limiting. They can be spread through respiratory droplets released when a person sneezes or coughs.
