Influenza, commonly known as the Flu, presents with a range of symptoms that can vary in severity. The most common symptoms include a sudden onset of fever, chills, body aches, and fatigue. These are often accompanied by a sore throat, cough, and a runny or stuffy nose. Headaches and eye pain may also occur, and some individuals, particularly children, might experience gastrointestinal symptoms such as nausea, vomiting, or diarrhea. The symptoms typically appear abruptly and can be more severe than those of the common cold.

Influenza Symptoms can last for several days to a week or more, with the most severe symptoms generally occurring in the first 2 to 3 days. It's important to note that not everyone with influenza will have a fever. In some cases, the illness can lead to complications such as pneumonia, especially in vulnerable populations like the elderly, young children, or individuals with underlying health conditions. If symptoms are severe or persist, medical attention should be sought to prevent further complications.

The terms Cold and Flu often get used interchangeably although they are different Illnesses. Their symptoms are very similar at first glance, including a stuffy or runny nose, sneezing, general fatigue, and body aches. However, the two conditions are caused by completely different viruses and over time with the illness, the symptoms will change to make it more clear which illness a person is suffering from. Flu symptoms tend to be more severe than those of a cold, and can also cause additional health conditions such as ear and sinus infections, pneumonia, and sepsis.

Your doctor will be able to determine which Illness you are suffering from and provide direction on Treatment if any. A common cold will go away on its own, typically within 10 days to 2 weeks, once it has run its course. Sufferers can manage symptoms as needed using over-the-counter cold medications, getting plenty of rest, and staying well hydrated. The flu on the other hand will typically start off with more severe symptoms that come on suddenly, over the course of a few hours, with symptoms clearing up over the course of a few weeks for most people.
