The U.S. is experiencing epidemic-level flu activity, the CDC announced yesterday.
The proportion of deaths related to pneumonia and influenza reached 6.8 percent as of December 20, 2014, which is considered the epidemic threshold. This demonstrates how easily the flu spreads, however an epidemic classification is typical with most flu seasons, the Washington Post reported.
“The CDC announcement confirms that we are entering a period of increased influenza transmission,” said Nick Kelley, PhD, research associate for the Center for Infectious Disease Research and Policy at the University of Minnesota. “We expect to see higher levels of influenza during this time of year, with peak transmission typically occurring in January.”
