Flu in children: how symptoms differ from a common cold

Flu in children: how symptoms differ from a common cold

Why flu and colds are easy to confuse Influenza and the common cold are both contagious respiratory viral illnesses, and in children they often overlap: cough, sore throat, nasal congestion, reduced appetite, and disrupted sleep can occur with either. Both spread through respiratory droplets and contaminated hands or surfaces, so a classroom, daycare room, or […]

RSV in children: symptoms, spread, and recovery

RSV in children: symptoms, spread, and recovery

What RSV is and why it matters in childhood RSV is an enveloped RNA virus that infects the respiratory epithelium, meaning the cells lining the nose, throat, airways, and lungs. Nearly all children encounter RSV early in life, and reinfection is common because immunity after infection is incomplete. Older children and adults often experience a […]

Croup in children: symptoms, home care, and warning signs

What croup is and why it sounds so distinctive Croup is a common childhood respiratory illness in which inflammation and swelling develop in the upper airway, particularly around the larynx, vocal cords, and trachea.

Why coughing often sounds worse at night Cough is a protective reflex designed to clear mucus, irritants, or secretions from the airway.

What bronchiolitis means Bronchiolitis is inflammation, swelling, and mucus accumulation in the bronchioles, the smallest conducting airways in the lungs. In babies, these airways are already very narrow. Even a small amount of edema and secretions can increase airway resistance, making breathing noisier and more effortful. The illness is usually caused by a virus that […]

Persistent cough in children: common causes and when to seek care

Persistent cough in children: common causes and when to seek care

What counts as a persistent cough in childhood Children cough frequently because their immune systems meet many respiratory viruses, especially in daycare, preschool, and school settings. A typical viral cough may continue after fever and congestion improve, often because the airway lining remains inflamed and sensitive. Even so, duration matters. A cough that lasts more […]
