The Importance of Disinfection in Offices After Flu Season: Protecting Your Workplace Health

As New Zealand’s flu season draws to a close, many business owners and office managers breathe a sigh of relief.

The worst seems to be over—fewer staff call in sick, productivity begins to return to normal, and business operations stabilise.

Yet, this moment creates a critical opportunity that, when overlooked, can undermine workplace health for months to come.

Research from Business New Zealand shows that workplace illness costs New Zealand businesses approximately $1.26 billion annually in lost productivity.

Each employee absence creates a ripple effect throughout your organisation, affecting deadlines, client satisfaction, and team morale.

While visible symptoms of illness may subside, the microscopic threats that caused them often remain embedded in your office environment.

What many don’t realise is that the end of flu season isn’t truly the end of risk. Viruses and bacteria can persist on office surfaces for days or even weeks after employees have recovered. Without proper professional disinfection, these pathogens continue to threaten your workplace health long after sneezing and coughing have subsided.

At Busy Bees, we’ve been delivering expert commercial cleaning solutions since 1993. Our three decades of experience have shown us that thorough office disinfection after flu season is not merely a cleaning task—it’s a crucial investment in your company’s productivity, staff wellbeing, and bottom line.

Why Disinfection Matters Even After Flu Season Ends

The Persistent Nature of Workplace Pathogens

Most business leaders would be surprised to learn just how resilient common workplace pathogens truly are.

Long after employees have recovered and returned to work, the viruses and bacteria that caused their illnesses can continue to thrive within your office environment.

Influenza viruses can survive on hard surfaces for up to 48 hours, while norovirus—a common cause of workplace gastroenteritis—can persist for days or even weeks.

The common cold virus can remain viable on office furniture and equipment for up to 24 hours.

These timeframes create ample opportunity for healthy employees to encounter and contract these illnesses, even when no one in the office is visibly unwell.

What makes this particularly challenging is that infected employees often contaminate workplace surfaces before they even know they’re ill.

Studies show people can shed viral particles up to 24 hours before showing symptoms, unknowingly depositing pathogens on doorknobs, light switches, shared equipment, and other surfaces throughout your office.

Breaking the Chain of Cross-Contamination

Understanding how pathogens spread through an office environment is crucial to preventing the ongoing cycle of illness.

The primary transmission method is through what cleaning professionals call “touch points”—surfaces that multiple people contact throughout the day.

Consider this common scenario: An employee who is just beginning to feel unwell touches a door handle, deposits viral particles, and then continues to their desk.

Throughout the day, dozens of colleagues use that same door handle, picking up the virus and transferring it to their own workspaces, phones, and eventually, their faces.

In fact, studies indicate that office workers touch their faces an average of 16 times per hour, creating multiple opportunities for self-infection.

Professional disinfection targets these high-risk touch points with hospital-grade products that effectively neutralise pathogens.

By breaking this chain of transmission, thorough disinfection prevents one employee’s illness from becoming a company-wide problem that continues long after flu season officially ends.

Beyond Influenza: Other Workplace Pathogens

While influenza receives the most attention during winter months, it’s far from the only pathogen threatening your workplace health.

Rhinoviruses (causing common colds), norovirus, rotavirus, and various bacterial infections like Staphylococcus aureus all readily spread in office environments.

Unlike seasonal influenza, many of these pathogens circulate year-round, making ongoing disinfection protocols essential for workplace health maintenance.

For instance, research from the University of Auckland has found that shared office equipment like keyboards and telephones can harbour bacteria counts up to 400 times higher than toilet seats when not regularly disinfected.

The New Zealand Ministry of Health reinforces this reality, noting that “regular cleaning and disinfection of surfaces is one of the most effective ways to reduce the spread of infections in workplaces and communities.” Their guidelines emphasise that maintaining hygienic environments is a year-round responsibility, not just a seasonal concern.

Professional disinfection addresses this broader spectrum of pathogens with comprehensive approaches that go beyond what standard cleaning can achieve.

By implementing thorough disinfection after flu season ends, you’re not only addressing residual influenza viruses but also establishing stronger defences against the many other pathogens that threaten workplace health throughout the year.

High-Priority Areas for Post-Flu Season Disinfection

When implementing a thorough post-flu season disinfection plan, it’s essential to identify and prioritise the areas where pathogens most commonly accumulate.

Our experience serving New Zealand businesses since 1993 has given us unique insight into the critical areas that require special attention.

Common Touch Points

The surfaces that multiple people contact throughout the workday represent the highest risk for pathogen transmission.

These high-touch points act as collection and distribution centres for viruses and bacteria:

Door handles and light switches: The average office door handle is touched up to 100 times daily. These small but frequently contacted surfaces can harbour viruses for up to 48 hours.
Elevator buttons and stair railings: In multi-level offices, these become unavoidable touch points for all staff and visitors. Their frequent use makes them particularly high-risk areas.
Shared equipment controls: Printer control panels, coffee machine buttons, water cooler dispensers, and other communal equipment all serve as collection points for pathogens from multiple users.
Conference room surfaces: Table surfaces, chair armrests, remote controls, and presentation equipment are handled by numerous people during meetings, creating multiple opportunities for cross-contamination.

Professional disinfection targets these areas with appropriate disinfectants and techniques, applying proper contact time and thorough coverage that casual cleaning often misses.

Personal Workspaces

While individual workstations might seem like personal responsibility, they play a crucial role in office-wide health:

Keyboards and mice: Studies have found that the average office keyboard harbours approximately 7,500 bacteria per swab—far more than many bathroom surfaces. Proper disinfection requires specialised techniques to remove pathogens without damaging sensitive electronics.
Desk surfaces: The typical office desk has 400 times more bacteria than a toilet seat, according to research. This concentration develops because desks serve as workspaces, eating areas, and resting places for personal items.
Phones and headsets: These items make direct contact with users’ faces, creating a direct pathway for pathogen transmission. Their close proximity to the mouth and nose makes them particularly high-risk items.
Personal items: Water bottles, stationery, eyeglasses, and mobile phones regularly move between homes and offices, potentially introducing new pathogens to the workplace environment.

A comprehensive disinfection plan includes proper treatment of these personal areas, requiring specialised products that are effective against pathogens while being safe for electronics and frequent human contact.

Communal Areas

Shared spaces create unique challenges for maintaining workplace health:

Kitchen and break rooms: Food preparation surfaces, refrigerator handles, microwave buttons, and dining tables all present cross-contamination risks. The combination of multiple users and food consumption makes these areas particularly important.
Reception areas: As the first point of contact for visitors, reception areas potentially introduce external pathogens to your workplace. Seating, countertops, sign-in equipment, and door handles all require thorough disinfection.
Bathroom facilities: Beyond standard cleaning, proper disinfection addresses flush handles, taps, door locks, and other high-touch bathroom surfaces that can spread both respiratory and gastrointestinal pathogens.
Meeting and collaborative spaces: Areas designed for group work naturally increase close contact between colleagues. Chairs, tables, shared technology, and whiteboard markers all serve as potential vectors for illness transmission.

Professional disinfection of these communal spaces not only removes existing pathogens but also applies protective treatments that can help reduce recontamination rates in these high-traffic areas.

The Science Behind Effective Disinfection Protocols

Understanding the science of proper disinfection helps explain why professional services in Wellington’s deliver superior results compared to standard cleaning procedures.

Effective disinfection requires specific products, precise application techniques, and expert knowledge.

Understanding Disinfectants vs. Cleaners

One common misconception is that cleaning and disinfection are synonymous—they are not.

Cleaning removes visible dirt, dust, and some germs through physical wiping and washing. Disinfection specifically kills pathogens through chemical action.

Standard office cleaning products typically remove 80-90% of visible soil but may eliminate as few as 3% of pathogens.

True disinfectants are regulated products that must demonstrate effectiveness against specific pathogens under laboratory conditions.

Different disinfectant classes work through various mechanisms:

Quaternary ammonium compounds disrupt cell membranes
Alcohol-based products denature proteins
Hydrogen peroxide creates destructive free radicals
Sodium hypochlorite (bleach) oxidises cellular components

Most critically, contact time—how long the disinfectant remains wet on the surface—determines effectiveness.

Many disinfectants require 5-10 minutes of wet contact to achieve their claimed kill rates, a detail often overlooked in casual cleaning.

Environmentally Responsible Approaches

At Busy Bees, we understand the growing concern about harsh chemicals in office environments.

Modern disinfection science has developed effective options that balance pathogen elimination with environmental and health considerations.

Plant-derived disinfectants using thymol (from thyme oil) or citric acid provide effective antimicrobial action while offering improved safety profiles.

Hydrogen peroxide-based systems deliver hospital-grade disinfection with minimal environmental impact, breaking down into water and oxygen.

These eco-friendly approaches are particularly valuable for offices with:

Staff members with respiratory sensitivities
HVAC systems where chemical residues may recirculate
Sustainability commitments and green building certifications
Food preparation or childcare areas

Our professional teams select appropriate products for each environment, ensuring effective disinfection without unnecessary chemical exposure.

New Technologies in Disinfection

Disinfection science continues to advance, with several innovations enhancing traditional methods:

Electrostatic application: This technology applies a positive charge to disinfectant droplets, causing them to actively seek out negatively charged surfaces. This ensures comprehensive coverage, even on irregular or hard-to-reach surfaces.
UV-C light disinfection: Short-wavelength ultraviolet light disrupts microbial DNA, preventing reproduction. While not a replacement for chemical disinfection, it provides supplementary protection for appropriate surfaces and spaces.
Microfibre technology: Advanced microfibre cleaning materials physically capture more microorganisms than traditional cloths, enhancing the effectiveness of disinfectants by improving surface preparation.

Busy Bees continually evaluates and incorporates evidence-based technologies that demonstrably improve disinfection outcomes.

Our approach combines proven traditional methods with appropriate new technologies to deliver superior results for your office environment.
