The Return of Syphilis in Australia: Why You Can’t Ignore the “Great Imitator”

For decades, syphilis was considered an infection of the past. Today, it is making a drastic and concerning comeback across Australia.

According to recent national health data, syphilis notification rates have surged, spreading well beyond high-risk groups and increasingly affecting the general population across both urban and regional areas.

Because its early symptoms are often painless or look like everyday skin irritations, it has earned the nickname “The Great Imitator.” Here is what you need to know about spotting the signs of syphilis, the danger of letting it progress, and how to get fast, discreet testing online.

What is Syphilis?

Syphilis is a highly contagious bacterial infection caused by Treponema pallidum. It is primarily spread through vaginal, anal, or oral sex with an infected person. Unlike some other STIs, you can contract syphilis simply through direct contact with a syphilis sore (known as a chancre)—even if you are using a condom, if the sore is located outside the protected area.

The Stages and Symptoms: Spotting the “Great Imitator”

Syphilis develops in distinct stages, and the symptoms are significantly different in each stage. This is why it is so easily confused with other conditions.

1. Primary Syphilis

The first sign is usually a single, small, firm, and painless sore called a chancre. It appears at the exact spot where the bacteria entered the body—often areound genitals, anus, or mouth.

• The Catch: Because the sore is painless and might be hidden inside the vagina or rectum, many people dont realise, or may pass it off as another general skin infection. The sore will heal on its own within a few weeks, but the infection remains in your body and continues to spread.

2. Secondary Syphilis

If left untreated, the infection progresses to the second stage a few weeks after the original sore heals. Symptoms at this stage are easily mistaken for a flu or an allergic reaction and may include:

• A rough, red or brown skin rash may appear on the palms or soles.

• Fever, swollen lymph glands, and fatigue.

• Patchy hair loss.

• Muscle aches and a sore throat.

These symptoms will again disappear without treatment, leading to a latent phase.

3. Latent and Tertiary Syphilis

During the latent stage, there are no visible symptoms, but the bacteria are still active. If syphilis remains untreated for years, it can progress to the tertiary stage, where it can cause severe, irreversible damage to the heart, brain, nerves, and organs.

Why Routine Testing is Your Best Defense

Because the symptoms of primary and secondary syphilis completely vanish on their own, “waiting to see if it goes away” is the most dangerous thing you can do. The only way to know for sure is through a simple blood test.

If you are sexually active with new or multiple partners, or if you notice any sores or rashes, getting a comprehensive STI screen is critical.
