The main differences between a cold and a flu is the intensity of symptoms, as well as where the respiratory tract is affected.
Generally speaking, flu symptoms are more intense and last longer than cold symptoms. With a cold, the upper respiratory tract (above the lungs) is more affected, while with the flu, the entire lung can be affected.
In addition, flus occur mostly in the winter time and are easily transmissible. A person infected with the flu in a closed room with other people can easily contaminate those around him/her.

Another condition called a "flu-like syndrome" can also present similarly to the flu. It can be caused by a flu virus or by another virus os bacteria. Common symptoms include fever, coughing, sore throat, muscular pain and headache.
Although the flu-like syndrome can be treated at home with rest and fluids, there are some cases in which symptoms can worsen and fever can become very elevated and persistent. Some people may even experience difficulty breathing. In these cases, you should proceed to a hospital for assessment and treatment with antibiotics, if necessary.
How to treat the flu
Treatment for the flu can be initiated with medication as prescribed by a doctor. Acetaminophen can help to lower a fever, while anti-histamines can relieve other symptoms, like a runny nose. Depending on the duration and intensity of symptoms, antivirals, like oseltamivir (Tamiflu), may also be prescribed. Check out other flu medicine that is commonly recommended for treating influenza.
Rest and plenty of fluids (water, tea, broths and fresh juices) are also recommended.
