Sexually Transmitted Infections (STIs): What You Need to Know

STIs affect millions of people every year, but most of them are treatable if caught early. Knowing the basics can save you from unnecessary worry, pain, or long‑term health issues. Below you'll find quick facts about the most common infections, how they show up, and what you can do to stay safe.

Common STIs and What They Look Like

Chlamydia is often called the “silent” infection because many people feel no symptoms. When it does show up, you might notice a burning feeling when you pee or unusual discharge. If left untreated, it can cause infertility.

Gonorrhea feels similar to chlamydia, with painful urination and discharge. It can also spread to the throat or eyes if you have oral or eye contact with infected fluids.

Syphilis starts with a small, painless sore called a chancre. The sore heals on its own, but the bacteria keep working inside your body, eventually causing rashes, fever, or even heart problems if you don’t get treatment.

Human papillomavirus (HPV) usually has no symptoms, but some strains cause genital warts while others can lead to cervical or throat cancers. A vaccine can prevent the high‑risk strains.

Herpes (HSV‑1 & HSV‑2) shows up as painful blisters or sores that can flare up many times. Even when sores aren’t visible, the virus can still spread.

How to Stay Safe and Get Treated

The best defense is a mix of protection, testing, and honest communication. Using condoms correctly every time you have sex cuts the risk of most STIs dramatically. For infections that spread through skin‑to‑skin contact, like herpes or HPV, condoms help but don’t eliminate risk entirely.

Regular testing is key, especially if you have new or multiple partners. Many clinics offer quick, free or low‑cost tests for chlamydia, gonorrhea, HIV, and more. You don’t need to wait for symptoms—testing is the only way to know for sure.

If a test comes back positive, start treatment right away. Most bacterial STIs (chlamydia, gonorrhea, syphilis) are cured with antibiotics. Viral infections like herpes and HPV aren’t curable, but antiviral meds can lessen outbreaks and reduce transmission.

Talk openly with your partner(s) about testing results and protection methods. It might feel awkward, but a short conversation can prevent a lot of trouble later. Remember, both of you deserve to stay healthy.

Don’t let myths hold you back. You can’t contract an STI from a toilet seat, and you won’t automatically get infected from a single kiss. Knowing the facts lets you focus on real risks and take practical steps.

Bottom line: use condoms, get tested regularly, and seek treatment without delay. A quick office visit can keep you on track and stop an infection from spreading to you or others. Stay informed, stay protected, and keep the conversation going.
