he flu lead to a more serious illness?Yes. The flu can turn into ear, sinus, or dangerous lung infections such as pneumonia. But most normally healthy children make a full recovery from the flu in three to five days.
How did get the flu?
Children usually become infected through contact with someone who has the flu or by touching infected items such as plastic toys and utensils. People can pass on the flu virus by touching, kissing, and coughing, and the hardy virus can live for up to two hours on the surface of objects like toys or bedposts. Because it's so easily transmitted in densely populated areas such as schools, the flu has the highest incidence among children ages 5 to 14.
Prevent
The flu virus is so easily spread through human touch, on objects, and in the air -- it's tough to guard your child against it. Teach her to wash her hands frequently to reduce her risk, keep her away from secondhand smoke, and provide a good diet to keep her immune system healthy. (Since people are most contagious during the 24 hours before symptoms appear, good hygiene is important at all times. :)
