When is the stomach flu season?

The stomach flu, also known as gastroenteritis, is caused by a viral infection of the digestive system. It is commonly associated with winter months, but it can occur at any time of the year. The peak season for the stomach flu in temperate climates is typically from November to March, although it can vary from region to region. In contrast, in tropical regions, the stomach flu season may be more pronounced during the rainy season.
