Information material for the Unified Health Day “Influenza and ARVI Prevention Day”

In December 2022, an increase in the incidence of various acute respiratory viral infections (ARVIs) caused by influenza viruses, parainfluenza, coronavirus, respiratory syncytial virus, adenovirus, etc., began. Currently, influenza A(H1N1) viruses are dominant among influenza viruses. A seasonal increase in influenza incidence was expected, and a similar situation is being registered worldwide. The influenza A virus currently circulating (or as it was previously called "swine flu") has lost its pandemic potential. During the rise in COVID-19 incidence, it and other respiratory viruses were displaced by coronavirus, and now there is a natural process of viruses that have always circulated returning to the epidemic process.

All ARVIs have some common symptoms, such as malaise, runny nose, cough, and fever; individual symptoms may vary depending on the causative agent. For example, while rhinovirus often causes nothing more than a runny nose, respiratory syncytial virus can affect the lower respiratory tract (bronchi and bronchioles), causing a more severe course of the disease, especially in young children. Influenza is characterized by a high, persistent fever for 3-5 days. Adenovirus infection, on the other hand, is characterized by a longer duration (fever, sore throat, conjunctivitis can last up to 2 weeks).

The main preventive measure against influenza and coronavirus infection is vaccination. The highest risk of severe disease occurs in children, elderly patients, pregnant women, people with chronic diseases, and those with weakened immunity. It is extremely important for individuals in risk groups to get vaccinated.

Vaccination of the region's population against influenza has been completed, covering over 40% of the population, including over 75% of individuals in risk groups.

To maintain health, it is also important to observe non-specific preventive measures: maintain a safe distance in crowded places whenever possible or wear a protective mask, adhere to respiratory etiquette, etc.

Necessary conditions for disease prevention are maintained at the region's facilities: cleaning and disinfection of premises, ventilation are carried out, and hand sanitizers are available, etc.

Healthcare professionals continue to conduct awareness campaigns among the public about the importance of adhering to all preventive measures: a healthy lifestyle, regular physical activity, spending ample time outdoors, a balanced and healthy diet, quitting smoking, and ensuring adequate sleep and rest. Ventilating rooms is crucial, as influenza prefers warm, dry air in enclosed spaces.

And most importantly, upon the appearance of symptoms, it is vital not to endanger your health and to seek medical attention promptly.
