Syphilis
Beware: this scary STD is making a comeback on the dating scene. Infection rates jumped by 17.7 per cent between 2014 and 2015, putting them at a 20-year high. According to USA Today, health experts believe the increase is due to relaxed attitudes about HIV and lax condom usage, less funding for STD awareness, and a rise in social media and dating apps. While syphilis can be cured with penicillin, it is often mistaken for other medical issues, and symptoms might not show up for 90 days. Symptoms include painless sores on the genitals, anus or mouth in the primary stage, as well as a non-itchy rash in the secondary stage, often along with fever, fatigue and muscle aches. If left untreated, syphilis can enter the latent phase for up to 20 years but eventually can cause dementia, paralysis, organ damage and death.
Now discover why it’s so important for boys as well as girls to be vaccinated against another STD.
Polio
Here’s the good news: polio – an infectious disease that can cause muscle weakness, paralysis and death – has been almost completely eradicated worldwide. But that took a massive, coordinated, 30-plus-year vaccination effort by a number of health organisations, including the WHO, the CDC, and the Bill & Melinda Gates Foundation. However, it is still endemic to Pakistan, Afghanistan and Nigeria; cases only number in the dozens, though. There is no cure, and once the infection starts, it has to run its course which is why prevention is so important. According to the WHO, if all polio vaccinations were halted today, the infection rate could skyrocket to 200,000 cases per year within ten years.

Gout
Once called the ‘disease of kings’, gout isn’t a contagion like many of the others on this list. It’s a painful form of arthritis, caused by a crystallisation of uric acid in the joints, and it’s exacerbated by eating foods rich in compounds called purines, such as red meat and certain fish, as well as by drinking beer and hard liquor. Currently, one in 20 Australians will experience gout, and its prevalence is increasing around the world. Experts believe the rise is due to a rise in obesity and high blood pressure, though hereditary factors also play a role in whether someone will develop it.
