There are several viruses circulating the country at present that may seem like the flu, but are viruses that need to run their course.  They also come with high sustained fevers, aches, and cold symptoms,  but are not FLU.  The actual FLU can be confirmed by a blood test and medications such as Tamiflu can be used to decrease the length and severity of the virus for you and your loved ones.  Its always wise to visit your medical provider when a fever is over 103 degrees or lasts for more than 3 days. These fevers may need to be treated with other medications or treatments and it is a good idea to be evaluated. Other times that a fever needs immediate attention are those that are accompanied by neck pain and a severed cough that is painful, phlegmy or bloody.
