5 Flu Strains Going Around This Season

As the winter months approach, the threat of the flu season looms large. With multiple flu strains circulating, it's essential to stay informed about the different types of influenza viruses that are going around this season. In this article, we'll delve into the five most common flu strains that are currently affecting people worldwide.

Understanding the Flu Season

The flu season typically runs from October to May, with the peak months being December, January, and February. During this time, the flu virus spreads rapidly, infecting millions of people worldwide. The flu is a highly contagious respiratory illness caused by the influenza virus, which affects the nose, throat, and lungs.

Why are there Multiple Flu Strains?

The flu virus is constantly evolving, which is why there are multiple strains circulating each season. The virus mutates, creating new strains that can evade the immune system. This is why it's essential to get vaccinated every year, as the vaccine is updated to protect against the most common strains.
