For weeks, the world has been inundated with information about the COVID-19 pandemic. While cases continue to rise and researchers learn more about the novel coronavirus (SARS-CoV-2), most data has lacked a certain specificity. But on Tuesday, the Centers for Disease Control and Prevention (CDC) was able to give a closer look at exactly who is most affected by COVID-19. In a new study published for the CDC's Morbidity and Mortality Weekly Report, researchers found that the majority of those hospitalized due to COVID-19 have preexisting conditions-about 90% of patients, or nearly all, had one or more underlying conditions. The most common ... include hypertension (49.7%), obesity (48.3%), chronic lung disease (34.6%), diabetes mellitus (28.3%), and cardiovascular disease (27.8%). The data collected for the study came from the COVID-19-Associated Hospitalization Surveillance Network (COVID-NET), created for population-based surveillance for all confirmed COVID-19-related hospitalizations in the US. The CDC's new study used the demographics of 1,482 COVID-19 patients ... from across 14 different states. The study found that 74.5% of those hospitalized due to coronavirus were age 50 or older, with the highest rates among those over 65. Men were also disproportionately affected (54.4% of those hospitalized from COVID-19 were male), as were African Americans, who represented 33% of hospitalizations, despite only making up 18% of the total population studied.
