What is the flu?
Influenza, commonly called the flu, is an infection caused by a group of viruses that change frequently and are highly contagious. Common symptoms include fatigue, fever, headache, muscle aches, sore throat and cough. The best way to prevent the flu is to get an annual vaccine (the flu shot). This is especially important for people more at risk of a serious infection like very young children, the elderly, and anyone with a lung disease or a condition that compromise the immune system. Covering your cough, staying home when sick and frequently washing your hands will help prevent you from spreading the flu if you do become infected. While there is no “cure” for the flu there are things you can do to feel better while your body fights the infection.
Should I get tested for the flu?
It depends on your doctor’s recommendation. The symptoms of the flu are very similar to symptoms of other viral illnesses like the Common Cold or COVID19. It is possible to have the flu and other viruses at the same time (including COVID19). Often times a flu diagnosis is made based on your symptoms and testing is not necessary, however if your doctor recommended testing, it is readily available at most Urgent Care Centers and Primary Care Clinics. The most common test is a nasal swab that provides rapid results (typically in one hour or less). As of now there is no combined test for the Flu and COVID19.
Anti-viral medications are available to treat Influenza, however they do not ‘cure’ the virus. According to the CDC anti-viral medications started within the first 2 days of symptom onset may reduce the severity of symptoms, shorten the course of illness by 1 day and reduce the risk of flu-related complications. Anti-viral therapy is recommended by the CDC for patients who are very sick or in a high risk group.
A common anti-viral medication used to help with flu Symptoms is Oseltavmivir, also know as Tamiflu. If your doctor prescribed Tamiflu please take it as prescribed. A typical prescription is for 5 days. The most common side effects of Tamiflu are nausea, vomiting, diarrhea and an upset stomach. If you experience any additional side effects please reach out to your doctor.
