Intro

A silent asthma epidemic could be affecting millions of people in Africa. It’s estimated almost half of all the asthma sufferers in the world live on the continent, but many face barriers to diagnosis and treatment. Dorcas Wangira, the BBC’s Africa Health Correspondent in Nairobi, Kenya talks us through the growing body of research looking into how asthma is affecting children and teens in Africa. We also hear from Doyin Ogunye, a campaigner for better air quality in Lagos, Nigeria, about the links between asthma and air pollution.
