Every winter, the flu returns and affects thousands of people in Switzerland. Although it is often taken lightly, it can nevertheless lead to serious complications, particularly amongst the most vulnerable. How can you reduce the risk of infection? What are the most effective ways to protect yourself and those around you? Here is an overview of the main preventive measures.
What is seasonal flu?
Seasonal flu (influenza) is an infectious disease caused by the influenza A and B viruses. It is highly contagious and is mainly spread through droplets released when coughing or sneezing, or through contact with contaminated surfaces. Unlike a common cold, the flu usually sets in suddenly and is often accompanied by a fever, chills, severe fatigue, muscle aches, headaches and a cough. In some cases, it can lead to complications requiring hospitalisation.
Why is flu prevention important?
The flu has a significant impact on public health every year. In Switzerland, it is responsible for numerous doctor’s appointments, hospital admissions and several hundred deaths each year. Older people, pregnant women, young children and those with chronic illnesses are particularly at risk of severe forms of the illness.
Preventing the flu therefore helps to:
- reduce the risk of infection
- limit complications
- protect vulnerable people
- reduce absences from work and school
- ease the pressure on the healthcare system
Key measures for preventing flu
1. Vaccination: the most effective form of protection
Vaccination remains the best preventive measure against flu today. It helps to reduce the risk of infection and significantly lowers the risk of serious complications in people at risk. In Switzerland, the health authorities recommend vaccination in particular for:
- people aged 65 and over
- pregnant women
- people with certain chronic conditions
- residents of care homes
- healthcare professionals and carers of vulnerable people
2. Adopt preventive measures against the flu
Vaccination can be complemented by a few simple habits that help limit the spread of respiratory viruses:
- wash your hands regularly
- cough or sneeze into your elbow
- use disposable tissues
- avoid close contact if you have symptoms
- wear a face mask when you are unwell or in high-risk situations
- ventilate enclosed spaces regularly
3. Stay at home if you have symptoms
When the first symptoms appear, it is recommended that you limit contact with other people to prevent the virus from spreading. This helps to protect your loved ones, colleagues and the most vulnerable people.
The challenges for businesses
Flu prevention is also a key issue for employers. Seasonal outbreaks can lead to increased absenteeism and affect the wellbeing of staff.
Promoting vaccination, reminding staff of hygiene measures and encouraging them to stay at home when they are unwell all help to create a healthier and safer working environment for everyone.
Prevention plays a vital role in workplace health management. It not only protects individuals but also strengthens collective resilience against seasonal illnesses.
In other words…
The flu is not a trivial illness. Fortunately, there are several measures that can effectively reduce the risks. Vaccination, combined with protective measures and good daily habits, remains the best way to protect yourself and those around you. Because good health is also built through prevention, everyone can help to limit the spread of the virus and get through the winter in the best possible condition. Take care !
