Infectious diseases


Influenza is a severe viral illness. There are many different types of influenza. Transmission is airborne – drop, ie, coughing and sneezing patient. Depending on the type of pathogen disease starts in a few hours or days after infection. In mild illness is lasting 3-4 days. However, after this, a person can infect others for a few more days.


  • Chills and fever (temperature rose to 40°C and more).
  • Headache.
  • Pain in the muscles and joints.
  • Cold symptoms (nasal congestion, cough, sore throat), or abdominal pain, vomiting and diarrhea.


Influenza is caused by a virus of several types (the most famous types of the virus – A, B and C). Viruses of type A are strong activators of influenza epidemics. So from 1889 to 1892 there were 500 million people suffering from the “Russian head cold”, “Spanish flu”, of which 22 million have died. We may recall the “Asian flu” of 1950, about half the world’s population suffered from this infection.

People of all ages are subject to flu, but the elderly are sick it harder than young.


People get a flu vaccinations in all countries. Immunisation protects against infection in about 80% of cases. However, influenza viruses are constantly changing, and the active substances are used previously for vaccination, lose effectiveness. So every time when there is a new influenza virus, it is necessary to create a new serum drug. As a rule, annual forecasts are created, and a vaccine against a possible epidemic is already ready for the fall. Vaccination protects against influenza is about 1-2 years. For additional protection, vaccination against the disease should be done every fall. But if a person is ill, then the flu virus will not have the proper effect. You can only help ailments, which is caused by the disease.

To relieve the symptoms of influenza antipyretics, medicines for headaches, vitamin C are used. In addition, bed rest is required. At high temperatures should drink plenty of liquids. Discontinuing bed rest can cause severe complications of influenza recurring – hearing loss, inflammation of the soft shell of the brain and spinal cord.

Calling a doctor is required when high fever or extreme heat, if it does not fall within 5 days after the onset of illness.

The flu can cause severe complications and associated diseases. Poor circulation is possible. If one of these conditions is suspected, the doctor will prescribe antibiotics or other medications.

Course of the disease

First, the patient has a general weakness, pain in the joints and muscles. Temperature rises, often up to 40°C. Antipyretic action is briefly. Usually after 5 days the body temperature becomes normal. However, a full recovery will be soon.

Is it a dangerous disease?

In healthy people, the flu is mild, without any complications. However, for persons with weakened immune systems influenza can even be life-threatening.


During the epidemic of influenza should follow the simple precautions: wash your hands, avoid contact with sick people.
