The United Kingdom has reported the presence of a more virulent strain of the virus, called N501Y; the WHO has said the variant has been found in Australia, Denmark, Iceland, Italy, and the Netherlands and it is assumed to be in the U.S. While more virulent, it has not yet been found to cause more severe disease than other variants. Notably, the UK does more viral surveillance than other countries.
FDA Takes Additional Action in Fight Against COVID-19 By Issuing Emergency Use Authorization for Second COVID-19 Vaccine

Comparison of the Characteristics, Morbidity, and Mortality of COVID-19 and Seasonal Influenza: A Nationwide, Population-Based Retrospective Cohort Study
A study compared ~46,000 patients hospitalized with influenza during the 2018–2019 flu season and 90,000 hospitalized with COVID-19 from March through April. The in-hospital mortality rate for COVID-19 was 3 times higher than influenza (17% vs. 6%). For adolescents, in-hospital mortality was 10 times higher with COVID-19 (1.1% vs. 0.1%). Patients with COVID-19 were more likely than patients with flu to develop acute respiratory failure, pulmonary embolism, septic shock, or hemorrhagic stroke but were less likely to experience myocardial infarction or atrial fibrillation.
