A to Z: Flu (Influenza)
More to Know
In the United States, flu season runs from October to May, with most cases usually occurring between late December and early March. The flu is often confused with the common cold, but the flu comes on more suddenly and is more severe.
Symptoms can include fever, sore throat, headache, cough, weakness, and loss of appetite. After 5 days, fever and other symptoms usually disappear, but a cough and weakness may continue for up to another week. Drinking lots of fluids, getting plenty of rest, and taking acetaminophen or ibuprofen to relieve fever and aches are some simple ways to cope with the flu.
It's important to treat the flu seriously, though, because it can lead to pneumonia, dehydration, and other life-threatening complications, particularly in infants, senior citizens, and people with long-term health problems.
Keep in Mind
You can protect yourself from the flu by getting vaccinated every year. The Centers for Disease Control and Prevention (CDC) recommend the flu vaccine for most people over the age of 6 months.
