Asthma is a lung condition that causes swelling of the airways. It can make breathing difficult and trigger coughing, wheezing and shortness of breath. It's the most common chronic disease among children, although it affects adults, as well. 

More than 262 million people globally are affected by asthma, and more than 461,000 have died due to the disease, according to the World Health Organization.

In childhood asthma, the lungs and airways become easily inflamed when exposed to certain triggers, such as inhaling pollen or catching a cold or other respiratory infection. Childhood asthma can cause bothersome daily symptoms that interfere with play, sports, school and sleep. In some children, unmanaged asthma can cause dangerous asthma attacks.

Childhood asthma isn't a different disease from asthma in adults, but children face unique challenges. The condition is a leading cause of emergency department visits, hospitalizations and missed school days.

Unfortunately, childhood asthma can't be cured, and symptoms can continue into adulthood. But with the right treatment, children can keep symptoms under control and prevent damage to growing lungs. Maintaining good day-to-day asthma control is the key to keeping symptoms at bay and preventing asthma attacks.
