The flu, or influenza, is a type of respiratory-tract virus that affects infants, toddlers and children more frequently than adults, reports KidsHeath, a health information website supported by the Nemours Foundation. The flu is contagious. Healthy children and adults who are close to a sick youngster should wash their hands frequently with soap and water to help prevent the spread of the infection.
Fever
A sudden, high fever is one of the first symptoms of the flu. Fever typically exceeds 101 degrees Fahrenheit and may persist for several days, warns BabyCenter, an informational website for parents and parents-to-be. Toddlers who develop a fever can appear flushed, and their skin may feel warm. Fever symptoms may also be accompanied by headache, chills or sweating, which can cause a toddler to become unusually fussy or irritable. A toddler with a fever should be seen by a medical professional as soon as possible.
Fatigue

Head and Body Aches
A toddler's whole body can hurt when he has a viral infection, according to the Centers for Disease Control and Prevention. The aches and pains are typically mild to moderate and can persist for several days. The toddler may complain that he doesn't feel well or that his head hurts. These uncomfortable symptoms can contribute to increased fatigue.
Nasal Congestion or Cough
This viral infection can irritate and inflame the respiratory tract, which can cause nose, throat and chest symptoms. A toddler with the flu can develop a stuffy or runny nose accompanied by sore throat or cough, reports KidsHealth. Nasal congestion can make it difficult for a toddler to breathe. Further, a sore throat or cough can cause the toddler to lose his appetite.
