The flu virus makes headlines every year, and it's not exactly because headlines read, "Nobody got the flu this season!" The best offense is a good defense, and people commonly take action when they notice a fever coming on. However, this isn't the only sign of the flu. There are a number of flu-like symptoms without fever that could be indicative of the virus — and they are equally important to be on the lookout for.
The flu season started early this year. It first reared its ugly head back in November, and by late December, it had hit every corner of the country. It's not over yet, and this could be among the nastiest flu seasons we've had in the last several years. The Centers for Disease Control and Prevention says it's definitely not the worst we've seen, though, compared to 2014 and 2015.
Still, the flu is always risky. In the United States each year, approximately 9 million to 35 million illnesses occur; there are 140,000 to 710,000 hospitalizations; and somewhere between 12,000 and 56,000 die from it. It's nothing to scoff at. Even if you're not noticing a fever, if you're experiencing one of the following symptoms, pay close attention and take care to address it — it could be a sign of the flu.
