What is Influenza?
Influenza, commonly known as “flu”, is a highly contagious viral infection caused by influenza A and B type viruses, affecting the respiratory tract (nose, throat and lungs). Although it is often confused with a simple cold, influenza is a much more serious systemic disease that can lead to hospitalization and can be life-threatening in risk groups.
This virus, which causes epidemics especially in the winter months, has the ability to constantly mutate (change its structure). This variable structure of the virus causes our immune system to perceive the virus as a “new threat” every year and the need for repeated flu vaccinations every year.
What are the Symptoms of Influenza (Flu)?
Unlike the common cold, which starts insidiously, influenza usually has a sudden and shocking onset. The person usually feels fine, but within a few hours they may notice that their symptoms are getting worse. The most common symptoms are:
- Sudden onset of high fever and chills: The temperature is usually above 38°C.
- Severe Muscle and Body Pain: Intense pain, especially in the back, arms and legs (feeling like you have been beaten).
- Dry and Persistent Cough: It is usually sputum-free but severe.
- Deep Fatigue and Malaise: The person may feel too exhausted to carry out daily tasks, which can last for weeks even after recovery.
- Headache and sore throat: Throbbing headaches are often seen around the eyes.
- Runny or stuffy nose.
- Digestive Problems: Vomiting and diarrhea may also accompany the picture in children, although this is less common in adults.

Differences Between Influenza (Flu) and the Common Cold (Colds)
Although these two diseases are often confused, knowing the main distinguishing features is important for proper treatment:
- Initial Shape While the common cold starts slowly and over a period of days, the flu comes on suddenly, all at once.
- Fire Status: In the common cold, fever is rare or very mild. In influenza, high fever of 38 degrees and above is very common.
- Body Pain While the common cold causes mild malaise, the flu causes severe muscle and joint pain.
- Energy Level: A person with a cold can usually manage on their feet, but a person with the flu may become bedridden due to extreme fatigue.
- Sneezing: Sneezing is the most prominent feature of the common cold; it is less common in influenza.
- Risk of Complications: While a cold can cause sinus congestion or earache, flu can have serious consequences such as pneumonia, bronchitis and heart problems.
Diagnosis and Treatment Methods
Influenza is usually diagnosed by a doctor's physical examination and assessment of symptoms. For a definitive diagnosis, swabs from the nose or throat taken in the early days of the illness can be used. Rapid Antigen Tests or more precise results PCR tests feasible.
Things to consider during the treatment process:
- Antibiotic Use: Since flu is a viral disease, antibiotics have no place in treatment and should not be used.
- Supportive Care: Drinking plenty of fluids, bed rest, antipyretics and painkillers are the main treatment methods.
- Antiviral Drugs: If necessary, the doctor may prescribe antiviral drugs within the first 48 hours of symptoms. These medicines can shorten the duration of the illness and reduce the risk of complications.
Importance and Protection of Vaccination
Grip aşısı, her yıl dolaşımda olması beklenen virüs tiplerine göre güncellenir. Aşı, gribe yakalanma riskini önemli ölçüde (%40-60 oranında) azaltmakla kalmaz; kişi hastalığa yakalansa bile sürecin çok daha hafif atlatılmasını sağlar ve hastaneye yatış oranlarını düşürür.
Transmission Routes and Risk Groups
The flu virus is transmitted by airborne droplets when an infected person coughs or sneezes. It is also transmitted by touching infected surfaces (door handles, telephones, etc.) and then putting your hands to your mouth, nose or eyes.
Groups at high risk include:
- Adults aged 65 and over.
- Children under 5 years of age (especially under 2 years).
- Pregnant women.
- People with chronic diseases (asthma, diabetes, heart disease, kidney disease).
- Immunocompromised individuals.

MEASURES TO PREVENT INFLUENZA TRANSMISSION IN OFFICES AND WORK ENVIRONMENTS
Closed office environments, common areas and plazas are favorable environments for the rapid spread of viruses. Institutional and individual measures to be taken in workplaces are critical both to protect employee health and to prevent loss of workforce.
1. Strict Monitoring of Hygiene Rules
- Proper Hand Washing: To prevent the spread of viruses, it should be a habit to wash hands with soap for at least 20 seconds, not just with water.
- Disinfectant Access: Ofis girişlerinde, toplantı odalarında ve masa aralarında en az %60 alkol içeren el dezenfektanları bulundurulmalıdır.
2. Environmental Cleaning and Ventilation
- Disinfection of Frequently Used Surfaces: Common contact points such as telephones, keyboards, door handles, elevator buttons, photocopiers should be cleaned and disinfected several times a day.
- Ventilation Filter maintenance of the ventilation systems of offices should be carried out regularly and fresh air circulation should be increased. Where possible, windows should be opened and the environment should be ventilated frequently.
3. Approach to Employees with Symptoms of Illness
- Stay at Home Policy: Employees with flu symptoms such as fever, severe cough or malaise should be encouraged to stay off work and rest at home. “Working sick” puts other workers at risk.
- Flexible Working: During pandemic periods, office density should be reduced by implementing flexible models such as home-office or shift work, if possible.
4. Personal Protection and Distance
- Social Distance: Arrangements should be made to keep a distance of at least 1-2 meters between employees in dining halls, rest areas and meeting rooms.
- Mask Use: Masks should be recommended, especially in crowded, closed and poorly ventilated areas or for people who feel symptoms of illness.
5. Vaccination and Health Awareness
- Education and Awareness: Employees should be informed about the differences between flu and cold, correct hand washing techniques and cough/sniffle hygiene (use of tissues or inside the elbow).
- Vaccine Promotion: Efforts should be made to encourage annual influenza vaccination, especially for employees in risk groups.
6. Emergency Planning
- Emergency action plans should be prepared for possible large-scale epidemics in workplaces, and it should be determined in advance in which cases the office will be closed or full remote work will be switched.
Proactive implementation of these measures plays a key role in creating a healthy working environment and ensuring a productive winter.
