 2021 CDC analyses1,2 provide the clearest picture to date of how common and costly sexually transmitted infections (STIs) are in the United States. CDC’s latest estimates indicate that 20% of the U.S. population – approximately one in five people – had an STI on any given day in 2018, and STIs acquired that year cost the American healthcare system nearly $16 billion in direct medical costs alone.
