Great question! There is no way to predict if you'll be enjoying the sun on the beach or bundled up in your hotel room shivering. As a general rule, the temperature in the sun allows one to enjoy the beach. However if a cold front blows through, it can be windy, cloudy and cold.
The symptoms indicating onset of flu include fever of around 102 to 106 degrees Fahrenheit, flushed appearance of the face, severe loss in energy levels, and body pain. Some people also have other symptoms like vomiting or dizziness. Generally fever caused by flu lasts for almost one or two days. Sometimes it may even last up to 5 days. When the patient has suffered the illness for 2 to 4 days, the body symptoms reduce and symptoms of respiratory problems occur.
Sometimes (though, less often) a person can even catch the flu by touching a surface or object that has the flu virus on it, and then afterward touching their own mouth, eyes, or nose. How long does the flu last? As harsh as the flu can be, the good news is that most people feel much better within one to two weeks. Most healthy adults become contagious the day before symptoms develop (which makes it trickier to prevent from spreading). They remain infectious for up to five to seven days after symptoms appear.
