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.
If you have flu, you generally start to feel ill within a few days of being infected. You should begin to feel much better within a week or so, although you may feel tired for much longer. You will usually be most infectious from the day your symptoms start and for a further three to seven days. Children and people with weaker immune systems may remain infectious for longer.
