We've all been there—standing in that cramped airplane lavatory, wondering what lurks on surfaces that hundreds of people have touched before us. For decades, one particular worry has haunted travellers: can you actually catch sexually transmitted diseases from those tiny toilet seats at 30,000 feet?
A leading antimicrobial resistance expert has finally put this persistent myth to rest, though her findings reveal there are other, more pressing hygiene concerns we should know about when using airplane facilities.
In this article
Meet the germ detective
Associate Professor Rietie Venter from the University of South Australia brings serious credentials to this discussion. With degrees from the University of the Free State in South Africa, a PhD from the University of Leeds, and twelve years of research at Cambridge University as a Royal Society Dorothy Hodgkin Fellow, she's now leading internationally acclaimed research on antimicrobial resistance.
Her recent investigation into airplane toilet hygiene tackles one of travel's most persistent fears: 'With so many bottoms in the same place, one obvious concern is sexually transmitted diseases'—but the reality might surprise you.
'You cannot get HPV or other sexually-transmitted diseases from the toilet; that is just not how these bacteria work'
The myth busted by science
The fear of catching STDs from toilet seats has been thoroughly debunked by medical science, yet it persists in our collective consciousness. The bacteria and viruses that cause sexually transmitted diseases simply can't survive on surfaces long enough to pose a transmission risk. They can only live in particular environments; a toilet seat won't cut it.
Bacterial STIs can't survive outside of your body's mucous membranes. For this reason, it's nearly impossible to contract an STI from a toilet seat. Even if an STD somehow made it onto a toilet seat, it's very unlikely that the infection would survive until the next person uses the toilet.
Why toilet seat STD transmission is virtually impossible
STD-causing organisms need warm, moist environments to survive and specific entry points into the body. Toilet seats provide neither the right conditions nor the direct contact necessary for transmission.
The real villain: toilet plume
While STDs aren't a concern, Venter has identified the actual hygiene issue airplane travellers should know about. When you flush the toilet, the germs inside the bowl shoot into the air, landing everywhere, including on you. Known as the 'toilet sneeze', 40-60 per cent of the particles present in a toilet bowl might travel, including one nasty — Clostridium difficile — which can then be inhaled and cause diarrhoea.
This phenomenon isn't unique to airplanes, but the confined space makes it particularly relevant. Droplets and aerosol particles can spray up to six feet out of the toilet when we flush. That's why public toilet seats often don't have lids—but this creates the perfect storm for airborne contamination.
Smart strategies for airplane loos
Venter acknowledges the challenge: 'When you flush the toilet, it's best to move quickly away, or the particles will land on you. You can't flush and run as you are trapped in the small space.'
Her surprising advice? Don't put the toilet seat down before flushing. 'You think the toilet seat being down is good [to block the sneeze], but this just generates pressure and, because the seal is not a vacuum, it will come out around the edges. You need to flush, stand as far back as you can, and then have basic hygiene, washing your hands.'
Airplane toilet hygiene essentials
- Stand as far back as possible when flushing
- Don't close the lid (it makes things worse)
- Wash hands thoroughly afterwards
- Consider flushing before use for a 'fresh bowl'
- Exit quickly after flushing
Bigger picture: air travel and your health
Interestingly, Venter points out that airplane bathrooms aren't the main health concern during flights. Given diseases like Covid are more likely to be transmitted via breathing in droplets from an infected person than from touching infected surfaces, you have more risk of exposure in the cabin than the bathroom.
Recent research presented at the American Society for Microbiology found that MRSA can survive for 7 days on airplane armrests, compared to 4 on toilet flushers—making your seat potentially more concerning than the loo.
The phone factor
Venter, who admits to taking her phone everywhere including the toilet, had a vested interest in studying phone contamination. 'We swabbed a group of phones and there was lots growing on them, but I was pleased to say no faecal organisms [from the bathroom]'—though plenty of other germs were present.
Cutting-edge research: toilets as health monitors
Recent groundbreaking research has found an unexpected use for airplane waste. Scientists analyzed lavatory wastewater from 44 international flights arriving in Australia from nine different countries, detecting nine high-priority pathogens and super-bugs, including some that are resistant to multiple drugs.
Five of the nine super-bugs were found in all 44 flight samples, and a gene conferring resistance to last-resort antibiotics was detected on 17 flights. This gene was absent in Australia's urban wastewater during the same period, suggesting it was likely introduced via international travel.
As researcher Ahmed notes: 'This is a proof-of-concept with real-world potential. We now have the tools to turn aircraft toilets into an early-warning disease system to better manage public health.'
Did you know?
Did you know?
Airplane toilets could become powerful early warning systems for tracking the spread of antibiotic-resistant superbugs—a health crisis predicted to kill more people than cancer by 2050.
Your takeaway for safer travels
The bottom line for Australian travellers over 60? That decades-old fear about catching STDs from airplane toilets is completely unfounded. The real hygiene concerns are much more manageable with simple precautions.
Focus on thorough hand washing, be strategic about flushing, and remember that your biggest health risks during air travel are likely sitting in the cabin with you, not lurking in the loo. As Venter emphasises: 'Most germs don't jump up your nose'—basic hygiene habits remain your best defence.
What This Means For You
The next time you're cruising at altitude and nature calls, you can approach that compact lavatory with confidence—armed with facts instead of fears.
