How to Avoid Catching a Cold When Everyone at Work Has One

Winter and colder weather significantly increase the risk of catching viral illnesses such as the common cold and influenza (the flu). These infections are highly contagious, making public places common sources of transmission. In particular, workplaces are one of the environments where colds and flu spread most easily among colleagues.

The common cold is a viral infection that affects the nose, mouth, pharynx, and larynx—the upper respiratory tract. Coughing, sneezing, and nasal secretions release tiny virus-containing droplets that spread easily through the air, by hand contact, or via frequently touched surfaces. Although the common cold is generally a mild illness, it is extremely contagious.

According to studies supported by the Spanish Society of Primary Care Physicians (SEMERGEN), around 21% of common colds are contracted in the workplace. Fortunately, adopting a few simple habits can significantly reduce your chances of becoming infected.

Maintain Excellent Hand Hygiene

Wash your hands thoroughly and frequently using soap and water for 15–20 seconds, paying particular attention to the areas between your fingers and under your fingernails. If handwashing is not possible, avoid touching your mouth, nose, or eyes, and use an alcohol-based hand sanitiser whenever available.

A useful additional tip is to use a tissue when touching frequently used surfaces such as door handles or taps if you suspect they may be contaminated.

Avoid Sharing Keyboards and Mobile Devices

Office keyboards, telephones, and mobile devices can harbour a surprising number of viruses and bacteria. During cold and flu season, it is wise to avoid sharing equipment whenever possible to minimise the risk of transmission.

Keep Your Workspace Well Ventilated

Many offices are enclosed spaces with limited air circulation. Opening windows and doors for around ten minutes each day helps improve ventilation and reduces the concentration of airborne viruses indoors.

Be Extra Careful on Public Transport

Buses, underground trains, taxis, and other forms of public transport bring together large numbers of people, many of whom may be coughing, sneezing, or touching shared surfaces. If possible, consider alternative ways of travelling to work during peak cold and flu season.

The same precautions apply when travelling by train or plane, where stations, airports, and enclosed passenger cabins can become environments in which viruses spread more easily.

Stay Home If You Are Ill

Many people continue working despite having a cold or even the flu. However, if your circumstances allow it, staying at home can help prevent the illness from spreading to colleagues.

Working remotely, where possible, can be an effective short-term solution for many professions while recovering.

Focus on Prevention

Preventive measures should continue outside the workplace. Simple healthy habits can strengthen your body's natural defences, including:

• Drinking plenty of fluids to stay well hydrated.

• Using saline nasal rinses when appropriate.

• Spending time outdoors in fresh air.

• Getting enough sleep and adequate rest.

• Eating a balanced diet rich in vitamins and nutrients.

Foods such as pears, cauliflower, mushrooms, garlic, onions, turnips, thyme, mandarins, and ginger can all contribute to a healthy immune system.

Many employers also support workplace health by maintaining well-stocked first-aid facilities and offering seasonal influenza vaccination programmes, helping reduce illness across their workforce.
