Sexually Transmitted Infections (STIs): Symptoms, Testing & Prevention

Sexual health, just like physical health, mental health, or emotional health, is an important part of health. Yet, for many people, talking about STIs (or sexually transmitted infections) feels confusing or uncomfortable. 

Let's change that. 

In this comprehensive guide, you'll learn:

• The difference between STIs and STDs

• Common STIs and their symptoms

• Early symptoms of HIV

• How to protect yourself and your partner(s)

• Testing options

• How to challenge the stigma to take control of your health

Let's start at the beginning- and build on that from here.

What’s the Difference Between STIs and STDs?

While these two terms are used interchangeably, they can mean separate things:

• STI (Sexually Transmitted Infection) - concerns the presence of an infection in the body. You may have an infection without any symptoms and still be contagious.

• STD (Sexually Transmitted Disease) - refers to the point that there is an infection and the infection is causing symptoms or health complications when it becomes a "disease".

Using the word "STI" is ultimately the most accurate because a lot of people can have infections and never know it.

List of Common STIs (With Symptoms)

Here’s a deeper look at the most common STIs, including what causes them, how they spread, and what to watch for.

1. Chlamydia (Bacterial)

• Symptoms (if present): Painful urination, abnormal discharge, lower belly pain, bleeding between periods
  
  

• Silent in 70–80% of women
  
  

• It can cause infertility if left untreated.
  
  

• Treatment: Antibiotics (easily curable)
  
  

 2. Gonorrhea (Bacterial)

• May infect the genitals, anus, or throat
  
  

• Symptoms: Discharge, burning urination, pelvic pain
  
  

• Can lead to PID (Pelvic Inflammatory Disease) and infertility
  
  

• Treatment: Antibiotics (some strains are drug-resistant)
  
  

 3. Syphilis (Bacterial)

• Stage 1: Painless sore (chancre)
  
  

• Stage 2: Rash, fever, fatigue
  
  

• Stage 3: Heart, brain, and nerve damage (if untreated)
  
  

• Treatment: Penicillin injection (highly effective)
  
  

 4. HPV (Viral)

• Over 100 strains; some cause warts, others cause cancer
  
  

• Most sexually active people get HPV at some point.
  
  

• Symptoms: Often none, sometimes genital warts
  
  

• Prevention: HPV vaccine (recommended for ages 9–26)
  
  

• Treatment: No cure, but vaccines and screening (Pap smear) can prevent complications
  
  

5. Herpes (HSV-1 and HSV-2)

• Symptoms: Painful blisters/sores on genitals or mouth, itching, flu-like symptoms
  
  

• Transmitted via skin-to-skin contact, even without visible sores
  
  

• Lifelong but manageable with antiviral medications
  
  

• Many people have herpes and don’t know it
  
  

 6. HIV (Viral)

• Weakens immune system by attacking white blood cells
  
  

• Symptoms: Flu-like illness in the first few weeks, then often none for years
  
  

• Without treatment, leads to AIDS
  
  

• Treatment: Antiretroviral therapy (ART) can control the virus
  
  

• People with HIV can live long, healthy lives with proper care
  
  

7. Trichomoniasis (Parasitic)

• Caused by a microscopic parasite
  
  

• Symptoms: Discharge, itching, strong odor, painful urination
  
  

• More common in women
  
  

• Treatment: Single-dose antibiotics
  
  

Less Common but Serious STIs to Know

• Hepatitis B and C - These are liver infections that are spread by sex or blood and are vaccine-preventable (Hep B only).

• Molluscum contagiosum - This is a viral skin infection that is spread through skin contact. 

• Pubic lice ("crabs") - These are parasitic insects that live on pubic hair and cause itching.

HIV: Early Symptoms and Why Testing Matters

Many people with early-stage HIV don’t realize it. Symptoms often occur 2–6 weeks after exposure and may include:

• Fever

• Sore throat

• Swollen lymph nodes

• Body aches

• Rash

• Night sweats

• Mouth ulcers

After this stage, HIV can lie dormant for years. Without treatment, it can weaken the immune system, which can put you at risk for infections and illnesses.

Getting tested early could mean better health and a longer life.

STI Prevention Tips (That Actually Work)

1. Always Use Barrier Protection

• Use condoms or dental dams every time you have vaginal, oral, and anal sex.

• Condoms made of either latex or polyurethane are best for the prevention of sexually transmitted infections.

2. Get Vaccinated

• HPV Vaccine (Gardasil 9) - Protects against nine strains, including those that cause warts and cancer.

• Hepatitis B Vaccine - Offers protection against a serious liver infection for life.

3. Limit Your Number of Partners

• More partners mean more risk.

• Try to limit sexual partners to those who only have sexual partners who also only have you (monogamous partners).

4. Communicate Openly

• Talk to your partner(s) about each other's STI statuses, previous testing, and protection.

• Make it a no-shame or blame space.

5. Get Tested Regularly

• Regular testing helps in early detection of possible infections, even in the absence of symptoms.

• If you're sexually active, you should be tested between every six months to every year, or maybe sooner, with multiple sexual partners.

How to Get Tested for STIs (And What It’s Like)

Places to get tested: 

• Sexual health clinics

• Government or private hospital

• Family planning clinics

• Youth wellness non-profit organizations

• At-home test kits (for chlamydia, HIV, etc...)

What the test may consist of: 

• Urine sample 

• Blood sample 

• Swab (vaginal, rectal, or throat)

• Physical examination (if symptoms are present)

Most test results return in 1-7 days, and rapid HIV tests can return a result in under 20 minutes.

How STIs Can Affect Mental and Emotional Health

Receiving a diagnosis of an STI can be frightening. But remember this one important thing: 

• You are not dirty or irresponsible. 

• STIs are common and treatable. 

• You are not defined by your diagnosis. 

• There are people, treatment, and a way forward. 

If you are experiencing anxiety, depression, or are feeling overwhelmed by your diagnosis, please seek help from a doctor, counselor, or support group. Your emotional well-being is important too.

How to Talk to a Partner About STIs

Yes, these discussions can be uncomfortable, but they are also empowering and responsible.

Here are some ways to make it easier:

Be calm and honest: "Before we get more intimate, I want us to talk about sexual health."

• Suggest testing together

• Share your testing history non-judgmentally

• Use "I" statements: "I care about both of us being safe."

• Great partners will respect your honesty.

Why Youth & Teens Need STI Awareness Too

Young individuals (ages 15-24) account for nearly half of all new cases of STIs globally. However, most of them do not receive clear, developmentally appropriate information. We must normalize:

• Regular STI testing

• Consent-based conversations

• Condom use

• Vaccines such as HPV

• Respect for personal boundaries
