According to new research from Queen Mary University of London, adults with asthma had an almost doubled risk of a severe asthma attack after Covid-19 limitations were loosened in the UK.Episodes of progressive worsening of asthma symptoms, termed exacerbations or asthma attacks, are the major cause of illness and death in this condition. Asthma affects more than 5 million people in the UK and more than 300 million globally.
