Do you see another pandemic for the avian influenza virus in today's world? People who believe that this is very likely because the increasing cases of avian influenza virus, the general spread of diseases, and the fact that many scientists believe it is not an issue of if What is it?
To answer that question, you first need to find out what the avian flu is and a part of its history.
Avian influenza, also known as avian influenza, is an avian influenza virus that causes disease. These viruses naturally occur in wild birds and are carried in the intestines. These viruses are highly contagious and usually do not do wild birds of sickness though.
Avian influenza was first recorded in Italy in 1878 over 100 years ago. As a cause of mass death in poultry, it became known as "chicken plague." The disease was recorded in the US in 1924-25 and was recorded again in 1929. In 1955 it turned out that the virus causing poultry plague was one of the influenza viruses. The official designation of avian influenza is influenza - A H5N1. This stock was originally originally isolated in 1961 as a bird from South Africa.
An unprecedented publicity that received this influenza that infects birds that I can think about It was reported for the first time in 1997. During this time, 18 people were hospitalized and 6 people died. In an attempt to control the outbreak, the authorities killed about 15 million chickens. This was an attempt to delete the source of the virus.
Since 1997, cases of people infected with viruses have been confirmed. Two children from Hong Kong were infected during that year, but both children recovered.
In 2003, two Hong Kong families were infected after traveling to China. One person died. The cause was not determined where, and how those two people were infected. After that, another family died of respiratory disease back to China, but no examination was done at that time.
Also in 2003 the Netherlands reported over 80 cases of avian influenza-A among poultry workers and their families. A patient died. At that time, it seemed there was evidence of human-to-human transmission. These occurrences narrowed ahead in the spring of 2004 but then appeared again in the summer.
Like Septum 19, 2005 114 has been confirmed to be human cases of bird flu and those of 59 that are fatal. Human cases have been reported in Vietnam, Thailand, Cambodia and Indonesia. There has been no sustained transmission from person to person, but in autumn 2004 there is another report that in Thailand the transmission from person to person is suspected. This virus recently shows the ability to jump from species to species by infection with cats, pigs, tigers and leopards. The areas affected by poultry H5N1 avian influenza include the following: Cambodia, China, Hong Kong, Indonesia, Japan, Laos, Malaysia,
So what is now all this possible influenza pandemic?
The first influenza pandemic is a new virus, the human population is immune. It will be a massive epidemic on a global scale with enormous amounts of death and disease. For worldwide transport, these epidemics will settle very quickly on a global scale, on congestion and urbanization.
This is why the recent findings on avian influenza viruses are particularly relevant. The reassortment of the genome of avian influenza (which is a genetic material change between the two types of virus making the third) can lead to these viruses infecting many species, exposure to many people, It infects. This new virus has new genetics immunized with the current vaccine. As shown, the world is facing the potential of a pandemic for a number of years with respect to avian influenza virus, and we are wondering whether or not a huge proportion of influenza pandemics will occur in weeks I do not know within a few years, but because all the conditions are in place, from humans
Let's take a look at the past pandemic history of influenza. This may give us a better understanding when we use a huge percentage of words. These earlier pandemics are leading to high levels of illness, death, social dislocation and economic loss. The potential devastation of avian influenza virus is greater than these previous epidemics.
3 Such a pandemic of influenza, has been in the 20th century.
When 1918-1919 more than 500,000 died in the United States alone, with about 500,000 people all over the world. In 1957 - 1958 Asia influenza first brought about 70,000 deaths reported in China later lunar month 1957 and it spread to the United States by the month of 1957. Hong Kong influenza in 1968 and 1969 caused some 34,000 deaths in the United States alone.
What will happen so when confronted with pandemic from bird flu virus today. There are also some reasons why the most agreeable stand is for a little containment. First of all, the world will be only a few weeks to achieve that feat. Scientists estimate that 300,000 to 1 million are soon with antiviral needs. There is limited stock at the moment. Therefore, the current time limit of production limit is four to six months to produce a certain amount of vaccine. This may not be fast enough. In fact, for containment, the world has a large immunization campaign within the time frame of two to three weeks for all types that may contain virus
There is also the chance that current vaccines for avian influenza will have little effect on pandemic virus. This is necessary to match the pandemic virus that the vaccine may not. After that the world will need a new vaccine. So, since there is no Thai development of vaccines, the other virus is another part of the world for the purpose of protecting customers. It took months to grow, and by that time millions may die.
After that, there is a distribution problem. It does not guarantee the priority of distribution. It occupies a majority of rich countries with poor country vaccines.
So, is it possible to deal effectively with our government and others doing a nightmare? What can you do as an individual?
4, in 2004, the order to immediate ban the importation of all birds from the Southeast Asian Cambodia, Indonesia, Japan, Laos, Hong Kong, Korea, Thailand, Vietnam and other areas immediately Hong Kong, poultry farm, live poultry market , Was removed from the ban list for vaccination, inspection, surveillance programs imposed for pet bird dealers; also was the reason for the inclusion of the list Hong Kong bird flu since the positive peregrine falcon Because there was no additional case of A (H5N1).
The World Health Organization has developed a system to effectively manage lead effort programs to develop national plans to cover aspects of response to pandemics that require enhanced monitoring and early detection The public Improving sanitation infrastructure is also a priority.
Also, a contract of egg surge capacity worth about $ 100,000 has been awarded. This was done to support the manufacture of the vaccine. Because the vaccine can provide a safe, effective and efficient means to prevent death from disease, disorder, infection, research high national institute with medical institutions to test new vaccine It is another organization that supports.
The only downfall is whether they take time to develop and not enough for trends like any new stock of viruses. This fact gives priority to reporting and early detection.
The World Health Organization Center Institute of Disease Control, Public Health Institute, Epidemiologists of the State and Territories, the Association of Councils of the Ministry of Health of Vietnam, which shows just a few positively influenced the influenza center of the world 112 monitoring and segregation It spans all continents of influenza virus. In that case, you will find a new, unusual influenza virus that reports immediately. They also implemented a new notice method for public health emergencies that is an international concern.
At this point in the US risk is very low due to a pandemic from avian influenza virus. This does not mean that the government is doing anything. French pharmaceutical company sanofi - aventis has won a $ 100 million contract to supply the US with a vaccine against H5N1.
The United States has also awarded a $ 2.8 million contract to the UK GlaxoSmithKline for antivirus 84,300 courses.It is not a vaccine but this antiviral Tamiflu shows the ability to protect from human infection. Purchasing is part of the US plan to buy a vaccine for 200 thousand people, and an antiviral for an additional 200 thousand people. ($ 17.2 million to $ 41.6 million, 242%) in protecting against influenza, including an increase for influenza and the creation of strategic protection / stockpiling ($ 0 to $ 80
