Symptoms of Flu

Thursday, March 26th, 2009

The pathogen of the flu is Mixovirus influenzae virus. It is a small ball containing RNA molecule and two superficial albumens – neuraminidase and hemagglutinin. This pathogenic agent is very unstable under the action of environmental aspects.

It quickly perishes in a dry room, under the influence of disinfectants, heating and the sun. But at low temperatures (-25C up to -70C) it can survive for several years.

During a contact to the patient the virus gets into the respiratory system through inhaling and takes root in epithelium cells (mainly in tracheas and large bronchial tubes).

The flu virus has ability to reproduce very quickly, therefore, the beginning of illness is usually sudden, in 12-48 hours from the moment of infection.

1. Virus parts reproduce, destroy the struck cell and go out immediately infecting next cells. That’s the reason of pain and smarts behind the sternum and dry coughing.

2. At the same time the virus results in the allocation of biologically active substances and products of cell disintegration, many of which are toxic for nervous, cardiovascular and other systems of the organism. The symptoms of intoxication are weakness, weariness, head and eyeball aches, especially when moving them and pressing on them; ache in muscles and joints, photophobia. High temperature, palpitations, tachypnoe, low blood pressure, puffiness are bleeding sickness are the other disturbing symptoms of the flue.

3. Virus attack results in decrease of immunity, occurrence of “holes” in the defensive systems of the organism. That’s why the flu frequently comes together with exacerbation of chronic diseases, bacterial complications such as cold, pneumonia, antritis, kidney defeat, etc. Quite often flu is accompanied with herpes and thrush.

In typical cases these symptoms start to regress after 5-7 days of illness and gradually disappear.
