Figure 1 is a diagram in two parts showing the signs and symptoms of asthma, and the risk factors. There are two series of circles linked together with lines around a central circle. The first has ‘Signs and symptoms’ at the centre, with: ‘wheezing’, ‘coughing’, ‘rapid breathing’, ‘laboured breathing’, ‘chest hurts’, ‘low energy’, and ‘fatigue’ arranged around it. The second has ‘Risk factors’ at the centre, with: ‘allergies’, ‘family history’, ‘respiratory infections’, ‘low birth weight’, ‘exposure to second hand smoke’, ‘low socioeconomic status’, and ‘living in an urban area’ arranged around it.
