Seasonal Affliction is a term used to describe illnesses that occur more frequently during certain times of the year. The most common example of this is the FLU, which is an infectious disease caused by a virus that affects the respiratory system. The FLU is highly contagious and can be spread through contact with an infected person or through the air. Symptoms include fever, chills, body aches, fatigue, and coughing. It is important to get vaccinated against the FLU each year in order to reduce the risk of infection.
