Notice to Readers: MMWR Reports Now Feature Altmetric Scores.

MMWR is now using Altmetric for Publishers (https://www.altmetric.com/), an online tool that gauges the impact of scholarly content beyond just citations, by tracking social media (e.g., Twitter, Facebook, and blogs), traditional mainstream and science-specific media (e.g., New York Times and New Scientist), as well as online reference managers (e.g., Mendelay), related to a report.
