How to reduce the spread of flu and bugs in the workplace

As we move through the colder months, cases of flu, colds, and other seasonal bugs increase significantly.

For businesses, this isn’t just a health issue, it directly affects productivity, staffing levels, and overall workplace well-being.

Taking simple, preventative steps can dramatically reduce the spread of illness at work and help protect your employees.

Why workplace hygiene matters

When illness spreads through a team, the impact is felt quickly:

• Increased sickness absence

• Reduced productivity

• Pressure on remaining staff

• Disruption to services and customers

According to the HSE's most recent statistics, there was an estimated 40.1 million working days lost due to work-related ill health and non-fatal workplace injuries.

It's thought that seasonal illness costs businesses thousands of working days each year

The good news is that many of these absences are preventable with basic hygiene and sensible workplace practices.

Common ways bugs spread at work

Viruses such as flu spread easily in workplaces due to:

• Shared equipment (keyboards, phones, tools)

• Close contact between colleagues

• Poor hand hygiene

• Inadequate cleaning of surfaces

• Staff feeling pressured to “work through” illness

Understanding how illness spreads is the first step to stopping it.

Practical steps to reduce the spread of illness

1️⃣ Encourage good hand hygiene

Regular hand washing is one of the most effective ways to prevent infection.

Employers should:

• Ensure hand washing facilities are well stocked

• Encourage staff to wash hands regularly, especially after coughing or sneezing

• Provide hand sanitiser in shared areas

• A box of tissues can reduce the use of sleeves and hands instead

2️⃣ Clean shared surfaces regularly

Viruses can survive on surfaces for hours.

Focus cleaning on:

• Door handles

• Light switches

• Keyboards and phones

• Break room surfaces

Even small increases in cleaning frequency can make a big difference.

3️⃣ Promote “catch it, bin it, kill it”

Provide tissues and waste bins throughout the workplace and encourage staff to:

• Catch coughs and sneezes in tissues

• Dispose of tissues immediately

• Wash hands straight after

This simple habit significantly reduces airborne spread.

4️⃣ Support staff to stay home when unwell

One unwell employee can quickly infect a whole team.

Creating a supportive culture where staff feel able to stay home when ill:

• Reduces overall sickness levels

• Protects vulnerable colleagues

• Helps staff recover faster

5️⃣ Educate employees about illness prevention

Clear communication helps staff understand their role in keeping the workplace safe.

Consider:

• Posters in communal areas

• Short reminders in team meetings

• Sharing trusted guidance from reliable sources

The NHS provides clear, up-to-date advice on preventing flu and common infections, including symptoms, hygiene practices, and when to stay home. Their guidance can be found on the NHS website and is an excellent resource for employers and employees alike.

The business benefit of prevention

Investing a small amount of time into illness prevention can:

• Reduce sickness absence

• Improve staff morale

• Maintain productivity

• Demonstrate a duty of care to employees

Healthy workplaces are not just safer — they are more resilient.

Supporting well-being at work

Looking after physical health goes hand-in-hand with mental well-being.

Clear communication, supportive policies, and appropriate training help create a workplace culture where employees feel valued and protected.

At Redfearn Training, we work with local organisations to support workplace safety and well-being through practical, in-house training tailored to real working environments.

Final thought

Seasonal bugs are unavoidable, widespread illness at work is not.

Simple hygiene measures, clear guidance, and a supportive culture can make a significant difference to your team’s health and your business continuity.
