In WHO ended “ pork “ hysteria ofof WHO (World Health Organization) officially declared the termination of a pandemic so-called “ pork “ flu H1N1 which victims were about 18,5 thousand people, report the Russian mass media.
“ Alarm Level “ pandemic “ in the world is not present any more. Now we entered the postpandemichny period “ - the head of WHO Margaret Chan reported.
The decision on cancellation of the mode of a pandemic was made on the basis of estimates of experts.
I will note that in the USA already began to get rid actively of vaccines against “ pork “ flu: millions of doses which were not useful literally throw out on a garbage can.
I will remind that the first outbreak of the H1N1 virus was recorded a year ago, and later few months officials of WHO declared the highest level of danger - a pandemic.
Today it becomes obvious that emotions, to put it mildly, were exaggerated. The whole year people were afraid and paid, cancelled trips and did not eat pork. The countries closed borders, and somewhere even martial law was imposed. It appeared, not plague, and deception of the 21st century, Vestie writes. Ru. Flu - the murderer appointed not that virus though that still can appear.
“ Pork “ flu (English Swine flu) - the conditional name of the disease of people and animals caused by influenza strains. The name widely extended in mass media at the beginning of 2009. The strains associated with flashes so-called “ swine flu “ are found among viruses of flu of a serotype of C and subtypes of a serotype And (And / H1N1, A/H1N2, A/H3N1, A/H3N2 and A/H2N3). These strains are known under the general name “ virus of swine flu “. Swine flu is widespread among domestic pigs in the USA, Mexico, Canada, South America, Europe, Kenya, continental China, Taiwan, Japan and other countries of Asia. At the same time the virus can circulate among people, birds, etc. types; this process is followed by its mutations.
Transfer of a virus from an animal to the person is a little widespread and correctly made (thermally processed) pork cannot be an infection source. Being transferred from an animal to the person, the virus not always causes a disease and often comes to light only on existence of antibodies in blood of the person. Cases when transfer of a virus from an animal to the person leads to a disease are called zoonozny swine flu. The people working with pigs are exposed to risk of infection with this disease, nevertheless, from the middle of the twentieth years of the 20th century (when identification of subtypes of a virus of flu for the first time became possible) only about 50 such cases were registered. Some of the strains which caused a disease in people gained ability to be transferred from the person to the person. Swine flu causes the symptoms typical for flu and a SARS in the person. The virus of swine flu is transmitted as through direct contact with the infected organisms, and vozdushno - a drop way.
The flash of a new influenza strain in 2009 which gained fame as “ swine flu “ it was caused by the H1N1 subtype virus possessing the greatest genetic similarity to a virus of swine flu. The origin of this strain is precisely unknown. Nevertheless the World organization for health protection of animals reports that epidemic distribution of a virus of the same strain did not manage to be established among pigs. Viruses of this strain are transmitted from the person to the person and cause diseases with symptoms, usual for flu.
Pigs can be infected with a virus of flu of the person and it could occur as during a pandemic of the Spanish flu, and flash of 2009.
the Main symptoms coincide with usual symptoms of flu - a headache, temperature increase, cough, vomiting, diarrhea, cold.
An essential role in pathogenesis is played by damage of lungs and bronchial tubes owing to strengthening of an expression of a number of factors - inflammation mediators (TLR - 3, γ - IFN, TNF α etc.) that leads to multiple damage of alveoluses, a necrosis and a gemorragiya.
Prevention is also abroad carried out by
For primary prevention of persons of category of risk the accelerated development of a vaccine for prevention of flu on the basis of a specific strain of the activator to the Russian Federation. In an instruction of WHO about high-pathogenic flu it is indicated the need to exclude close contact with people, which “ the bodies having high temperature and cough " seem unhealthy;. It is recommended to wash carefully and rather often hands with soap. “ Adhere to a healthy lifestyle, including a full-fledged dream, the use of healthy food, physical activity “. At due heat treatment the virus perishes.
At university of Southampton established a bactericidal role of surfaces from copper and alloys of copper concerning the A/H1N1 virus. So, if within 24 hours on a surface from stainless steel about 500,000 units of a virus remained, then on a copper surface in 1 hour 75% of total number of units of a virus were inactivated, and 6 hours later active there were only 500 units (0. 075% of initial quantity). In Germany and Great Britain production of household and water fittings from bactericidal copper alloys is already begun.
Treatment can be created by
At the person imparted (by vaccination) and congenital immunity.
Treatment of the diseases caused by the majority of strains “ swine flu “ Amantadin, Zanamivir, Oseltamivir who, however, possess limited efficiency is carried out by means of preparations.
The majority of the known antiviral means is inefficient at the disease caused mutating “ Mexican “ A/H1N1 strain. At the moment full-fledged medicine against this strain of A/H1N1 does not exist - the existing drugs can only facilitate the illness course, especially at its early stages (in cases when the patient asks for medical care within 48 hours after emergence of the first symptoms of an illness).
It is not necessary to use the means containing aspirin in connection with risk of development of a syndrome of Ray, writes “ Wikipedia “.
