WHAT 'THE INFLUENCE
The name "Influence" goes back to the '400 and derives from an ancient astrological concept of this disease that the disease was caused by the influence or influence of the stars on individuals. But flu symptoms were described by Hippocrates more than 2400 years ago. There have been many throughout history pandemic influenza, which were responsible for the deaths of many people.
Influenza is a viral infectious disease caused by RNA viruses of the family of Orthomyxoviridae. It is characterized by symptoms of acute inflammation of the upper airways and general malaise (fever is not always present, malaise, headache and musculoskeletal pain and breathing, cough, sore throat) common to many other viral diseases. The onset is usually abrupt and sudden fever lasts 3-4 days.
The infection occurs through the nasopharyngeal secretions. In Italy and throughout the western hemisphere influenza occurring during the winter.
There are several types of influenza viruses that can infect humans as well as animals and cause pandemics spread to more countries. Type C viruses infect humans sporadically, usually never cause epidemics and tend to remain stable antigenically. Those of type B infect humans and animals and do not undergo antigenic mutations, may therefore cause epidemics of limited entity. Than type A infects both man and animals, and are subject to significant antigenic variations, are the ones that cause major pandemics. In fact, influenza pandemics are due to the selection of a new strain of influenza type A, such that individuals, even if infected with influenza A virus in previous years, have no antibodies able to recognize and effectively inactivate it.

VACCINATION AGAINST INFLUENCE
Vaccination is the most effective solution against influence. The World Health Organization (WHO) has established centers of observation and detection for influence in the world. In this way, from the first strain manifests itself in an epidemic, one can predict the type of vaccine to be administered in nations still not affected. And the survey should be done every year, which is why the Italian pharmacies flu vaccine always arrives late fall is manufactured according to the measurements of the strains most frequently carried out during the spring and summer in the countries where the epidemic influence is already in place. Influenza vaccination is usually practiced by injecting intramuscularly viral surface components extracted and purified. The efficacy of the vaccine begins to manifest after 2-3 weeks after administration and is due to the formation of specific antibodies to surface proteins of the virus.
