World Asthma Day on the first Tuesday of May

May 7, 2024 is the 26th World Asthma Day, and this year's theme is to strengthen asthma education, with scientific information dissemination being key, aiming to enhance people's understanding of asthma and strengthen public awareness of asthma prevention, treatment, and management concepts.

Asthma is a common chronic respiratory disease that affects over 300 million people worldwide. It is mainly manifested as chronic inflammation of the respiratory tract, leading to recurrent spasms and narrowing of the airway. Symptoms can be mild or severe, and when symptoms suddenly begin to appear, it is called an "asthma attack", which occurs when the narrowing and inflammation of the lung airway worsen. There are about 45 million asthma patients in China, which has become an important disease affecting national health.
