Who is the Discoverer of Influenza?

The influence comes from an Italian word for influence. It is a contagious viral disease that can infect humans, birds and mammals. The virus spreads through the air or some form of physical contact. The result is a viral infection in the person suffers from headaches, fever, cough and malaise. Some people may also develop a sore throat, diarrhea, vomiting and nausea.

First reports of flu-like symptoms
This disease is very old looking at human evolution.The story began as a credible theory that has been done, when people began their animals. Hippocrates kept the ancient greek medical records first flu symptoms almost 2400 years. The same was observed also identified in the same period a greek historian Herodotus.

Influence through the centuries
The first outbreak of influence in Eastern Europe was recorded in 1580. According to experts, began in Russia andAfrica and then spread to Central Europe. Thousands have been killed by this epidemic. Dr. JS Koen observed in 1918 that the same symptoms as human and pig were.

Orthomyxoviridae the strain of the virus was discovered in 1931 and was assisted by Richard Shope. He studied the symptoms of influenza in pigs in 1928 with N. McBryde. That infects healthy pigs with the virus after their samples of mucus. Has shown that the influence was caused in fact byVirus.

Influenza viruses often change from time to time, usually mutations - is the change in viral RNA. This change allows you to adjust the frequency of the virus to the host's immune system to avoid, so that the host is susceptible to infection with influenza virus throughout the life-changing.

Types of influenza viruses
There are three types of influenza viruses: A, B and C. A is the most flexible, and can thrive anywhere. Currently there arealmost fifteen serotypes HA, NA and nine serotypes. Because the virus constantly changes, there to present unknown subtypes. Type B infects only mammals and is less than type A. It has no known serotypes. Influenza type A and B cause epidemics of respiratory illness that occur almost every winter and are always associated with increased rates of hospitalization and death could.

Type C infect humans, but rarely causes serious illness, it is usually caused eithera very soft respiratory sickness or absolutely no symptoms. It also does not have any known serotypes. It also does not cause epidemics and does not have severe health impact of influenza Type A and B.

Traits of Influenza
The influenza virus is therefore extremely small and has a size of about 80 to 120 nanometers in diameter. It appears spherical under a microscope. The external side of the virus has a fatty layer covered with glycoprotein spikes. Deep inside the fatty layer is a line of proteins.

Influenza in modern times
The modern flu epidemics are less deadly as compared with epidemics in the past. Modern medicine proved successful in stopping its spread. However, some worst flu epidemics in the last century were the Asian Flu of 1957, great Swine Flu of New Jersey in 1976 and also in Russia in 1977. The recent epidemic that has scared the world is known as the H1N1 virus and research studies are going on to know about its origin.
