Does the Flu Happen Throughout the Year?
The influenza virus can occur throughout the year. However, it is more dangerous in its peak season. Also, you can have the Flu anytime, regardless of the season. People with an unstable immune system [1] can get the Flu anytime, even when the season has not arrived.
You may spend most of your time inside when the weather is cold. This makes you more susceptible to viruses, such as the Flu. It also increases the chances of spreading the virus. Your nasal passage may also be affected by the dry weather and cold. In addition, the flu virus thrives in a cold environment.
The flu does not leave during the summer. It only becomes less active. The flu is always in the air. According to studies, places with high sunlight may experience fewer cases of influenza. Studies show sunlight may play a significant role in protecting you against the flu. But more research needs to be done to understand the relationship.
According to research, the flu cases begin to reduce around April in the United States, ending by May.
