Flu season has begun; it’s not too late for a shot Published Jan. 10, 2014 By Kimberly Woodruff Tinker Public Affairs TINKER AIR FORCE BASE, Okla. -- Flu season is under way and widespread activity is being reported in 25 states, including Oklahoma, according to the Centers for Disease Control's weekly flu advisory report. This year the H1N1 virus is the most common strain being reported. This is the same strain that caused a pandemic in 2009 and killed thousands. The CDC warns that the situation is likely to get worse before February when flu season typically peaks. The flu usually comes on suddenly and though the symptoms can be similar for a common cold, it is not always easy to tell the difference. With the flu, there is usually, but not always, a fever and chills. Other symptoms include cough, runny, or stuffy nose, sore throat, headache, muscle aches, feeling tired and sometimes vomiting or diarrhea. Flu vaccines are recommended for everyone 6 months and older, especially pregnant women and those at high risk of complications, including the elderly, children younger than 5 years and those with underlying medical conditions such as asthma or diabetes. The flu vaccine is the best defense, but also eating healthy, getting plenty of rest and vigilant hand washing is recommended to avoid catching the flu.
