WHAT IS AN "EPI WEEK"?
An epidemiological week, commonly referred to as an epi week or a CDC week, is simply a standardized method of counting weeks to allow for the comparison of data year after year. Many people know these as CDC weeks because CDC uses them and has published them in the past. Nevertheless, they are used throughout the world by epidemiological teams in different countries.
