Influenza or “flu”- is a serious infectious disease that is caused by specific viruses. The infection is characterized by a very acute onset with the symptoms of intoxication, high temperature, headache and etc.. Unfortunately, our body is pretty much exposed to the flu virus. The best way to avoid flu is to get a flu vaccination every year. However, if you didn’t have the chance to get the vaccine timely, make sure that you know what other preventive actions are, and how to treat flu if you got sick.

Medical experts suppose that in most cases the flu is passed on through tiny droplets, that are produced when we talk, breathe, cough and sneeze. You might get infected if the droplets get into your nose, mouth or sometimes eyes. In rare cases, the infection can be caught when you touch a surface or an object, that has a flu virus on it.

The contagious period of the disease lasts for 3 or 4 days. The virus can be transmitted from a person to person even if the disease-carrier does not have any symptoms. Normally, the symptoms appear suddenly in one day after the infection. Sometimes it takes up to 7 days to realize that there’s an illness in your body.

It is important to detect the flu virus in the body and start the proper treatment timely. Otherwise, the disease may have complications that include pneumonia, infections of ears, asthma, diabetes or others.

You might need a medical attention if you feel some or all of the following flu symptoms:

  • High body temperature combined with excessive sweating. The body temperature starts to rise in a few hours after the infection. It can be accompanied by the chills and fever. The temperature can remain abnormally high for 2-5 days. Some doctors do not recommend to take antipyretic medicines, because the high temperature actually helps to fight the disease.
  • Weakness is one of the most common symptoms seen both in adults and children. When the body is infected, it spends a lot of energy on combating the virus. Hence, there’s a feeling of energy shortage.
  • During the flu throat is severely inflamed, which in 90% cases causes cough. When coughing, the throat surfaces irritates even more, and micro-traumas can appear. These processes can exacerbate the illness.
  • Dizziness and headache. These symptoms are caused by the waste products of the disease microorganism in the body. Quite frequently, the patient experiences pain in the eye socket as well.
  • Redness and swelling in the nasal pharynx.

If you have these flu signs, it’s better to stay home to avoid worsening of the disease and spreading it to other people. Consult with a doctor to choose the most appropriate treatment strategy.
