You’re standing in line at a local favorite like Two Scoops Creamery, chatting with a friend, when the topic of sexual health comes up. One says “STD,” the other says “STI”, and suddenly you’re both wondering, is there really a difference? And more importantly, which term should you actually be using?

At AFC South Charlotte, we understand how confusing and even uncomfortable these conversations can be. But understanding the terminology is a crucial step toward protecting your health. In this blog, we’ll explore the difference between the terms “STD” and “STI,” why medical professionals often prefer one over the other, and how our clinic can support you with confidential and accessible testing and care.

What’s the Difference Between an STD and an STI?

The short answer is that both terms refer to conditions transmitted primarily through sexual contact and are often used interchangeably. However, there is a meaningful distinction between the two.

STD stands for “sexually transmitted disease,” a term that’s been widely used for decades. It describes infections that have developed into diseases, meaning they’re showing symptoms or causing health complications. Examples include herpes with visible sores, or HIV that has progressed to AIDS.

STI, on the other hand, stands for “sexually transmitted infection.” This term is more accurate from a medical standpoint because an individual can carry an infection without showing any symptoms. In fact, many of the most common STIs, such as chlamydia or HPV, are often asymptomatic in the early stages. That doesn’t mean they’re harmless, left untreated, they can cause serious complications like infertility or certain cancers.

In simple terms, all STDs start as STIs, but not all STIs progress into STDs. That’s why many health experts now use “STI” to better reflect the full range of conditions that may or may not be symptomatic.

Why “STI” Is the Preferred Term Today

The shift from “STD” to “STI” isn’t just about accuracy. It’s also about reducing stigma. The word “disease” often carries negative connotations that may discourage people from seeking help or talking openly about their health. “Infection” tends to feel less alarming and more manageable, which can lead to earlier testing, treatment, and open conversations about prevention.

Many medical organizations, including the Centers for Disease Control and Prevention (CDC), now favor the term “STI” in public health messaging. That said, both terms are still in circulation, and you may encounter “STD” in educational materials, conversations, or pop culture references. What matters most is not the label, but the awareness and actions you take to care for your sexual health.

Why Testing Matters

STIs are incredibly common. The CDC estimates that nearly 1 in 5 people in the United States has an STI at any given time. Many of these infections go unnoticed due to a lack of symptoms, which is why routine testing is so important, especially if you are sexually active, have multiple partners, or are starting a new relationship.

Regular testing allows for early detection and treatment, reducing the risk of long-term complications and preventing the spread to others. At AFC South Charlotte, we offer a confidential, non-judgmental space where you can get tested quickly and easily, no appointment necessary.

Common STIs You Should Know

Being informed about common STIs helps you make better decisions about your health. Here are a few to be aware of:

• Chlamydia: A bacterial infection that often has no symptoms but can lead to pelvic inflammatory disease and infertility if left untreated. It is easily cured with antibiotics.
• Gonorrhea: A bacterial infection that affects the genitals, throat, or rectum. Like chlamydia, it is treatable but can cause serious issues if not caught early.
• HPV (Human Papillomavirus): The most common STI. Some strains cause genital warts, while others increase the risk of cervical and other cancers. A vaccine is available for protection.
• Herpes Simplex Virus (HSV): Causes oral and/or genital sores and is highly contagious, even without visible symptoms.
• Syphilis: A bacterial infection that progresses in stages. If untreated, it can lead to severe health problems. It is treatable in its early stages.
• HIV (Human Immunodeficiency Virus): Attacks the immune system and can lead to AIDS. While there is no cure, modern treatments allow people with HIV to live long, healthy lives.
