Winter in sight: Prepare for a wave of respiratory viruses
Flu viruses and COVID-19 are preparing to visit us, putting our immune system to the test
The arrival of autumn brings not only a pleasant change of season, but also an increased risk of contracting respiratory infections. Flu viruses, COVID-19 and other pathogens are preparing to visit us, putting our immune system to the test.
Why is autumn the season of viruses?
There are several reasons why autumn is the most favourable time of year for the spread of respiratory viruses:
- Thermal changes: The transition from hot to cold weakens our immune system, making us more susceptible to infections
- Less exposure to sunlight: The reduction in hours of sunlight affects the production of vitamin D, which is essential for our immune system
- Increased time spent indoors: With the onset of cold, we tend to spend more time indoors, encouraging the transmission of viruses from person to person
- Humidity: The increased humidity in the air creates an ideal environment for virus proliferation
Flu and COVID-19
Seasonal flu and COVID-19 continue to pose a threat to our health. The increase in COVID-19 cases recorded in August, fuelled by the emergence of new more contagious variants, such as Sars-CoV-2, presages a challenging autumn and winter. In addition, there is the threat of seasonal influenza, which may be early due to low temperatures.
A “viral cocktail”
Experts predict a “viral cocktail”, with possible co-circulation of both viruses, increasing the risk of complications, especially for older people, young children and those with chronic diseases.
How to protect yourself
To reduce the risk of respiratory infections, it is essential to take some simple precautions:
- Getting vaccinated: The flu vaccine and COVID-19 vaccine are the most effective tools to prevent diseases and their complications
- Wash your hands often: Frequent washing of the hands with soap and water or a disinfectant gel is essential to eliminate the viruses from your hands
- Cover your mouth and nose: When coughing or sneezing, it is important to cover your mouth and nose with a tissue or the elbow of your sleeve
- Keep your distance: It is advisable to maintain a safe distance from other people, especially in crowded environments
- Ventilate: Opening windows and regularly ventilating rooms helps to reduce the concentration of viruses in the air
- Strengthen the immune system: A healthy diet, good rest and physical activity help to strengthen the immune system
