Why syphilis is rising around the world

Syphilis has been called many names since the first record of it in the 1490s, most of them uncomplimentary – "the French disease", "the Neapolitan disease", "the Polish disease".

One however has stuck: "the great imitator". Syphilis is a master at mimicking other infections and early symptoms are easy to miss. Left untreated, the consequences can be serious.

Tushar, a 33-year-old project officer in Amsterdam, has had syphilis twice. He remembers first receiving the news via WhatsApp from his sexual partner at the time.

"They were really upset," he says. "They blamed me which wasn't possible because of the window period. It felt strange to be accused and it took some time to de-escalate." Tushar got tested and treated that week. "People mistakenly think syphilis is something that cannot be cured. People don't understand what it means to still have syphilis antibodies and not have the infection."

In April, the US released its latest data on sexually transmitted infections (STI). Cases of syphilis saw the largest increase, with cases surging 32% between 2020 and 2021 to reach the highest number of reported incidences in 70 years. The epidemic is also showing no signs of slowing, the Centres for Disease Control and Prevention (CDC) warned. And it has pointed to some "alarming" new trends driving this sudden spike in the disease.
