According to the U.S. Centers for Disease Control and Prevention’s (CDC’s) latest weekly report, the percentage of people visiting the doctor for flu symptoms jumped last week from 3.8 to 4.3 percent, the highest of the current flu season. This level, however, is much lower than last year’s peak of 7.5 percent. The report also noted that the number of states experiencing high flu-like illness activity increased from 23 to 24 states. And the number of states reported widespread flu activity rose from 45 to 47 states. The CDC expects flu activity to remain elevated for a number of weeks. Read the report at the CDC.
