Flu Facts: What You Need to Know About Influenza This Season
Influenza, commonly known as the flu, is an acute respiratory infection caused by influenza viruses that circulate worldwide. Each year, it affects millions, leading to severe illnesses and, in some cases, tragic loss of life.
Global Impact
Annually, influenza is responsible for approximately 1 billion infections around the globe. Of these, 3 to 5 million cases result in severe illness, with an estimated 290,000 to 650,000 deaths due to respiratory complications, according to the World Health Organization (WHO).
Seasonal Patterns
In temperate climates, flu season typically peaks during the winter months. However, in tropical regions, influenza can occur year-round, causing outbreaks at irregular intervals. Recently, many countries in the Northern Hemisphere have observed an increase in acute respiratory infections, which is expected at this time of year.
Symptoms: Flu vs. Cold
It can be challenging to distinguish between the flu and the common cold because they share many symptoms. However, influenza often includes more severe fever, chills, muscle or body aches, and can lead to serious complications. Colds are usually milder and generally do not result in serious health problems. Special tests can determine if a person is sick with influenza.
Staying Healthy
The WHO recommends several measures to protect yourself and others from influenza:
- Consider wearing a mask in crowded or poorly ventilated spaces.
- Cover coughs and sneezes with a tissue or your elbow.
- Practice regular handwashing with soap and water.
- Get vaccinated as recommended.
By following these guidelines, you can reduce your risk of infection and help prevent the spread of the virus in your community.
