  • A case-control study determined that Black and multiracial people were three times as likely to be admitted to a hospital for COVID-19 treatment when compared to white people living in the same neighborhoods in London. Cases were defined as patients admitted to the hospital for COVID-19 and controls were drawn from an administrative database in the same area. After adjusting for comorbidities and socioeconomic status, the admission risk for COVID-19 remained 2.2 to 2.7-fold higher. Racial/ethnic minority patients were on average 10–15 years younger than white patients, but had a higher prevalence of comorbidities, such as diabetes, hypertension, and chronic kidney disease.
