Published for World Hand Hygiene Day – 5th May
When we think about infection control, our minds often go straight to hand hygiene—and rightly so. But there’s an equally important, often invisible partner in the fight against healthcare-associated infections (HAIs): clean, high-touch surfaces.On this World Hand Hygiene Day, we spotlight how hand hygiene and touch point cleaning go hand-in-hand to support safer healthcare environments, especially in medical centres, day surgeries, and allied health clinics across Australia.
What Are High-Touch Surfaces?
High-touch surfaces are any areas frequently touched by hands—both by healthcare workers, patients, and visitors. These surfaces can easily become contaminated with microorganisms and serve as silent carriers of infection.
Common examples in hospital and clinic settings include:
- Door handles and push plates
- Light switches and lift buttons
- Chair arms and bedside rails
- IV pumps and blood pressure cuffs
- Bathroom fixtures (toilet flushes, sink taps)
- Shared equipment like keyboards, phones, and remote controls
- Reception desks, sign-in kiosks, and pens at check-in counters
- Handrails in waiting areas, corridors, and staircases
- Cafeteria trays and vending machine buttons
- Surfaces in visitor pick-up zones and patient bedside tables
These surfaces are touched often and frequently overlooked in daily cleaning routines if clear protocols aren’t in place.
The Link Between Hands and Surfaces
Here’s the catch: clean hands can become contaminated just by touching a dirty surface. Similarly, dirty hands can transfer pathogens onto clean surfaces. Without a combined strategy, one undermines the other.
This interplay is sometimes referred to as the “circle of transmission”—a chain of contact points that can enable the spread of infection if not disrupted. Breaking this circle requires two actions working together:
- Proper hand hygiene (e.g., washing or sanitising at the right moments)
- Consistent and effective disinfection of high-touch surfaces
At Namoli, we don’t just clean—we protect. That means implementing healthcare-grade cleaning routines tailored to your environment and aligned with national guidelines.
How to Disinfect High-Touch Surfaces Effectively
When it comes to disinfecting high-touch surfaces, the method matters just as much as the frequency. Here’s what effective cleaning looks like:
- Use TGA-approved disinfectants proven to kill bacteria and viruses
- Clean from cleanest to dirtiest areas to reduce cross-contamination
- Apply the correct dwell time (the time a disinfectant needs to stay wet on a surface to be effective)
- Always use colour-coded microfibre or disposable cloths to prevent transfer between zones (e.g., red for bathrooms, blue for general areas)
Replace cleaning cloths after each use and follow the 3 – part system: a set of cloths and mops in use, one in the wash, one as backup
How Often Should High-Touch Surfaces Be Cleaned?
Cleaning frequency depends on:
- Surface usage (e.g. shared between multiple people?)
- Patient risk level (immunocompromised, post-surgical, etc.)
- Setting (e.g. day surgery theatre vs waiting room)
As a general rule, high-touch surfaces in clinical zones should be:
- Cleaned multiple times daily
- Disinfected immediately after visible contamination
- Audited regularly to ensure compliance
At Namoli, we enhance routine cleaning with objective testing (e.g., protein surface testing and bioluminescence testing) to provide visible proof of hygiene and peace of mind to staff and patients alike.
Clean Hands + Clean Surfaces = Safe Care
In honour of World Hand Hygiene Day, we encourage every healthcare facility to re-evaluate not just handwashing practices but also their touch point cleaning protocols. Because when hands and surfaces work together, infections don’t stand a chance.
