Las vías respiratorias son conductos que transportan el aire para permitir su ingreso y egreso de los pulmones. Si tiene asma, en ocasiones las vías respiratorias pueden inflamarse y estrecharse. Esto dificulta el flujo de egreso del aire por las vías respiratorias cuando exhala.</p>

<p>Alrededor de 1 de cada 13 personas en los Estados Unidos tiene asma, según los Centros para el <a href="https://www.cdc.gov/asthma/most_recent_national_asthma_data.htm" rel="noreferrer">Control y la Prevención de Enfermedades</a> (en inglés).  Afecta a personas de todas las edades y, con frecuencia, comienza durante la niñez. Ciertos elementos pueden iniciar o empeorar los síntomas del asma, como el polen, el ejercicio, las infecciones virales y el aire frío. Estos se denominan desencadenantes del asma. Cuando los síntomas empeoran, se denominan crisis asmática.</p>

<p>No hay una cura para el asma, pero el el tratamiento y un plan de acción para el asma pueden ayudar a manejarlo. El plan puede incluir realizar monitoreo, evitar los desencadenantes y usar medicamentos.</p>
