In veel medische publicaties wordt gesproken over een 'astma-epidemie’. Twee voorbeelden (ik heb ze niet vertaald):
"The global epidemic of asthma that has been observed in both children and adults is still continuing, especially in low to middle income countries, although it has subsided in some developed countries".
"In the United States, asthma is a bona fide public health epidemic: 17 million adults and 7 million children suffer from the disease. Every year, our society pays in excess of $53 billion to treat it. Millions of asthmatics, including hundreds of thousands of kids, make visits to the emergency room for medical attention. And in thousands of severe cases, people die".
