Deaths were 12 times higher among patients with reported underlying conditions (19.5%) compared to those without reported underlying conditions (1.6%).2 Two-thirds of people in the UK who have fallen seriously ill with COVID-19 were overweight or obese and 99% of deaths in Italy have been in patients with pre-existing conditions, such as hypertension, diabetes and heart disease.3 These conditions, collectively known as metabolic syndrome, are linked to impaired immune function,4 and more severe symptoms and complications from COVID-19.5
