In Australia, influenza contributes to an estimated 18,000 hospitalisations each year, particularly during peak flu season, which increases the risk of workplace transmission in shared environments. Cold and flu prevention in the workplace is a key part of maintaining productivity, reducing absenteeism and protecting staff wellbeing.
How the flu spreads in the workplace
Influenza spreads primarily through respiratory droplets when an infected person coughs, sneezes or talks, and these droplets can settle on surfaces where the virus may remain active for several hours, increasing the risk of indirect transmission through shared contact points. Workplaces create multiple points of contact where viruses can spread, including shared equipment, close proximity between staff and common areas such as kitchens or meeting rooms.
Transmission is further complicated by the influenza A contagious period, which typically begins one day before symptoms appear and can last for up to five to seven days after onset. In Australia, seasonal flu outbreaks often lead to increased workplace absences during winter months, as employees may unknowingly spread the virus before recognising symptoms.
How to prevent the spread of flu in the workplace
Effective cold and flu prevention in the workplace focuses on reducing transmission and supporting early action across teams. Small changes to policies, behaviour and workplace setup can significantly reduce the spread of illness.
Encourage staff to stay home when unwell
Clear sick leave policies help reduce transmission, particularly during peak flu periods. While it varies by organisation, employees are generally advised to remain at home until symptoms have resolved and they are no longer contagious.
Promote hand hygiene
Provide hand sanitiser stations and encourage regular handwashing to reduce the spread of viruses through shared surfaces. Placing sanitiser in high-traffic areas reinforces consistent use throughout the day.
Improve workplace cleaning practices
High-touch surfaces such as desks, keyboards, door handles and shared equipment should be cleaned regularly, especially during flu season. Clear cleaning protocols help maintain consistency across teams and shifts.
Support vaccination uptake
Annual flu vaccinations can reduce the risk of infection and lessen symptom severity. Employers can support uptake by promoting awareness and making access to vaccinations easier where possible.
Encourage respiratory etiquette
Covering coughs and sneezes, using tissues and disposing of them properly can significantly reduce the spread of respiratory droplets. Reinforcing these habits through reminders or signage helps normalise good hygiene practices.
How to manage absences and maintain workforce coverage during flu season
Even with strong flu prevention in the workplace, some level of absence is expected. Plan ahead to reduce disruption and maintain day-to-day operations.
Plan for short-term coverage
Identify backup staffing options in advance, including casual pools, agency support or internal float staff to cover gaps at short notice.
Cross-train staff where possible
Training employees across multiple tasks or roles can help maintain service delivery when team members are unavailable.
Set clear absence and return-to-work processes
Staff should know when to report symptoms, how to access sick leave and when it is appropriate to return, particularly during the influenza contagious period.
Use flexible staffing arrangements
Adjusting rosters or bringing in additional support during peak periods can help maintain continuity without overloading existing teams.
