COVID-19 infections have been back on the rise during the last few weeks, particularly in Northeast states such as New York, Connecticut and Massachusetts, although overall cases have dropped sharply nationally since hitting record levels in January, according to data from the agency.
Daniel Kuritzkes, chief of division of infectious diseases at Boston's Brigham and Women's hospital, said the trend of an overall decline in cases has now reversed. The seven-day moving average of US COVID-19 cases stood at 28,339 as of April 9, up nearly 10% from a week earlier, the CDC said, with BA.2 accounting for 85.9% of infections.
