SHOULD THE GRYA'S BIRD WILL CREATE A NEW FLAME VIRUS
Why, then, the death of several people in Asia causes a great deal of concern each time?
Why is the millions of specimens of breeding birds nowadays annually ordered by the experts of the World Health Organization (WHO) after finding out that the poultry is infected with the H5N1 virus? Why is a thorough disinfection of poultry farms, stores, warehouses, restaurants - almost everything that has been in contact with them? It is certainly about the safety of poultry farming. But the main cause of this brutal epidemiological caution has been the same for decades.
FEAR OF MUTATION OF THE VIRUS AND PANDEMIC FLAME!
Asian type of human virus type A
The influenza pandemics so far (among others in the years 1889-90, 1918, 1948-1949, 1957, 1968) began in the Far East. Even the flu called the Spanish - it consumed about 20 million victims, more than World War I - came to us from Asia. Each time the culprit was a type A influenza virus, also isolated from birds and breeding mammals, which most often only know breeders and veterinarians.
Replacement of influenza virus genes
Pathogen exchange is possible between pathogenic strains of human influenza virus, other mammals and birds. This has been documented and described in the professional literature. If there is a rapid exchange of genes between the avian influenza virus, a virus of some mammal - for example, susceptible to the transformation of the virus with a breeding pig and a human virus - a new, more dangerous variety of human influenza may arise.
Potential deadly threat!
It would inherit the ability to rapidly spread among humans from the "version" of humans, and the virulent virulence from the H5N1 virus. A creature could be created for some time immune to the currently recommended vaccine and capable of decimating the human population.
Can the bird flu virus mutate in the future and be able to spread between people?
Such a risk always exists. All influenza viruses have the ability to quickly mutate. It is more likely to replace the genes of the avian virus in a triangle: birds, mammals, humans, which has already taken place and was the documented cause of the deadly pandemic. Perhaps, however, as a result of the mixing of human genes and avian viruses, a pathogen of avian influenza will arise that is capable of spreading rapidly between people and causing a pandemic. This is a scenario that sleeps with epidemiologists and ... us all. Fortunately, this is not a threat on a scale of weeks, but a risk spread over long months or years. In the meantime, it is a race against time to produce a human immunization vaccine for the most dangerous bird flu virus.
Note: 10-40 million people suffer from influenza every year
He is dying of flu from several to several dozen thousand. During a pandemic (getting sick in large areas, even around the world), the flu virus kills millions of people.
