Flu activity in the United States could continue to rise for several weeks, according to Dr Carrie Reed, chief of the epidemiology and prevention branch of the CDC's influenza division."There's a lot of influenza out there right now," she stated, emphasizing that the current season is expected to remain elevated into the spring months.
