Who gets asthma?

Asthma occurs in adults and usually starts in childhood.

Worldwide between 235 and 300 million people live with asthma and, every year, an estimated 250,000 die as a result of the condition.

According to the World Health Organization (WHO), most asthma-related deaths occur in low- and lower-middle income countries.

In South Africa, asthma occurs in 0.14% to 14.5% of children and 3.7% to 15% of adults, while the prevalence of asthma is 10% of the population.
