STI vs. STD?
Most people have at least heard of the terms STDs and STIs. However, people often don’t understand the difference between an STD and an STI. Although the terms Sexually Transmitted Infection (STI) and Sexually Transmitted Disease (STD) are used interchangeably, they are by no means identical. An STI is an important and scientifically valid term because dangerous pathogenic organisms can be present in the human body without causing disease. STDs result from damage caused by an STI that has progressed. Although all STDs are preceded by STIs, not all STIs result in the development of STDs.
There are dozens of STIs. Review the following to learn more OR visit the CDC information pages: https://www.cdc.gov/std/general/
