Seasonal flu follows a fairly predictable pattern, starting in the fall and ending in the spring. A good sign that it’s started is the sudden rise in the number of school-aged children sick at home with flu-like illness. This first outbreak is soon followed by a flu uptick in other age groups, especially adults.
Relief can be found with plenty of rest, drinking fluids and by taking pain relievers and decongestants, according to Merckmanual.com. Sometimes an antiviral medicine like Tamiflu is prescribed, but this type of medicine works best if given at the initial onset of symptoms.
