Recent research on the epidemic of Spanish flu, published by 1918 5. February 2004, in Science Express, the online version of the journal "Science" confirms our worst fears already suggesting that began with the birds. 1918 outbreak of influenza has killed 20 to 40 million people around the world, of which at least 500,000 in the United States. The survey was the result of a long-term collaboration between the late Don Wiley, a researcher at the Howard Hughes Medical Institute,Researchers at Harvard University and Sir John Skehel of the National Medical Research Institute of Medical Research in London.

The results are finally revealed the mechanism by which influenza-infected killer cells and has been for the death of many millions of people younger than many of the elderly population some immunity to the jurisdiction of a virus, had developed similar to previous their lives. The Spanish flu virus is extinct, but the researchers were able toStudy of viral DNA sequences by analysis of biopsies of infected tissues from the bodies of American soldiers died in the pandemic of Intuit and get a woman whose body was in the permafrost in Alaska. The scientists used X-ray crystallography, the three-dimensional structure of the virus of 1918 'shows surface haemagglutinin (HA) protein, a molecule that is known to initiate the first steps of viral infection. The protein binds to receptors on the cell surface and causes the poresOpened in human cells, allowing the virus to cross.

The HA protein, the force produced by the human influenza virus and other birds to different types of cell receptors, which is very important to be difficult for the bird flu virus that infects humans and vice versa. The document shows how this molecule, or the HA-binding site are similar to flu could infect humans, but when researchers discovered that the two sides of the receptor-binding haemagglutinin in slightly different positions inCompared with the 1918 hemagglutinin, the protein of Hong Kong, so that the human receptor to bind to an antigen so favorable. This means that during the pandemic of 1918, resulting in a change of avian influenza HA protein appears to bind to the virus, with deadly efficiency of human cells, while maintaining the basic characteristics of avian influenza virus, which has been developed.

While some scientists have long argued, the Spanish flu had nothing to do with the birds, many othersI suspect it becomes a bird flu virus had somehow "jump" from birds to humans. The results of this work are more important than a strain of H5N1 bird flu virus, as is known, has recently been spreading like wildfire across Asia and has 12 people were killed. Haemagglutinin of the 1918 virus was designated H1, the Asian flu, which began in 1957, the H2 and the strain in Hong Kong, in 1968, began H3.

It is expected that many scientistsbelieves it has the potential of a human pandemic, if not stopped quickly. UNFAO WHO and the World Organization for Animal Health has in common an urgent appeal for funds for new avian influenza, which they say could stop quickly, "an efficient and dangerous human pathogen. Many Asian countries have mass culling of infected poultry, as the best way the spread of potential pandemic control. This program has radicallyinfluenced by a widespread feeling that health authorities in Asia is not fast enough last year to the SARS virus, a human pathogen previously known to contain some 800 people killed. Apart from being highly contagious influenza viruses have the ability to adjust quickly through the exchange of genes, which change with the other, so that if someone had to be combined with a human flu virus catches the bird flu in two strains within the body of a new patienthighly contagious and fatal human plague. We also know that the two pandemics of 1957 and 1968 were caused by human immunodeficiency virus or animal hybrid mixtures.

Fortunately, as in the outbreak in 1997 in Hong Kong, almost all patients who appear to have been infected with H5N1 so far have spread through direct contact with infected birds. A growing concern about two sisters who died of disease in Vietnam, last month, which is probably aware, capturedbrother. There was also concern over a period of five years who had contracted the disease has played in the 7 December 2003, of chickens, but his two young cousins, who are less than a week later but was still playing at his side in hospital . The WHO said the current outbreak of H5N1 in poultry in South Korea began in December, but many believe that the outbreak probably began several months before the companies in southern China, where ducks are common in the rooms with pigs andPeople.

There is no doubt that earthquakes in California, another global influenza pandemic is "inevitable and possibly imminent", but the world out of poverty, which were different at the end of World War II, to begin with, there is now a global communicable disease surveillance system to warn if the virus H5N1 has begun to show direct evidence from person to person. We have a better antiviral drugs and treatments were available, the many millions whosuccumbed to the pandemic in the last century. At best, we can say that this transmission of the H5N1 virus from person to person, as shown on television every day with gloves, but the employee only masks, seem to break down the poultry carcasses to be ineffective in barrels.

Another study led by Ian Wilson of Scripps Research Institute in La Jolla, Calif., also recently published in Science, conducted confirmed that birds were the source of the 1918-strain. Although there have beenoutbreaks of bird flu infecting humans, until an outbreak of H5N1 in poultry in Hong Kong in 1997, is now thought that all the worst flu epidemics in the past century, including in 1957 the Asian flu and influenza Hong Kong emerged in 1968 with l '. Birds

The recall most of us who died in 1997, 6 people after contact with infected birds and made the decision to the whole flock of poultry in Hong Kong, killing about 1.5 million birds in just three days. Ofdeny the influenza virus can infect more opportunities for humans, can have a quick action averted a pandemic. So let's just hope that we stop this outbreak of the H5N1 virus to stop before tackling other global problems.

Centers for Disease Control background information on pandemics
A flu pandemic is global epidemic of influenza and occurs when a new influenza virus produces, it spreads throughout the world and the causes of the disease. Flu pandemics of the past have led to highStages of illness, death, economic losses and social. There were 3 pandemics in the 20th Century. All of them are spread all over the world within 1 year of discovery. They are:

1918-19, Spanish flu known cause "[A (H1N1)], the highest number of flu deaths: more than 500,000 people have died in the United States and from 20 to 50 million people worldwide have lost their lives. Many people died in the first days after infection and others died of complications soonafter. Almost half of those who died were healthy young adults.

1957-58, "Asian flu" [A (H2N2)] caused about 70,000 deaths in the United States. First identified in China in late February 1957, the Asian flu in the United States in June 1957 to spread.

1968-69, "Hong Kong flu" [A (H3N2)] caused about 34,000 deaths in the United States. This virus has been detected in Hong Kong in early 1968 and distributed in the United States by the end of the year. Type A(H3N2) viruses still circulate today.

The swine flu virus has become one of the words most frequently used in recent months. This is a new strain of virus was detected in Mexico in the spring of 2009. Since then it has spread around the world in the pockets of children, the number of international travelers who have left Mexico at the same time. The scientific name for the H1N1 virus is just another form of flu virus that we all know as the common cold. Nicknamed "the plague> Flu "because they come from pigs, swine influenza virus has spread rapidly, but not as deadly as people say it should be.

First, we must understand where the swine flu. It is a mutation of the virus that causes colds. He started with the pigs, birds as the virus has begun to infected birds. But not in this case of swine fever is spread by pigs. The outbreak of swine flu around the world in generalinfected by companies is on board of many international flights. Due to lack of adequate and sufficient swine flu vaccine for the early diagnosis, many of these companies share the ability to adapt to others. Therefore, H1N1 has been brought to the stage of a pandemic, the panic of the United Nations and beyond. Since then, the checks must be much more severe and have found that their effectivenessthe treatment of swine influenza.

As already mentioned, the origin of the H1N1 is assumed to Mexico. However, the genetic profile of the virus has similarities with almost all viruses have often been shown in some parts of South America, Asia, Europe and various islands in the Pacific. E 'was also linked to the Spanish flu, but no concrete evidence has been found on this media. From today, we all know that is fatal if not detected byvery long, very similar to the influenza virus.

Regardless of where it came from the swine flu, which has declared a pandemic. Extends as regards the influence normal, caused by contact with the carrier. Coughing and sneezing can spread the virus to other people when inhaled respiratory droplets. Any other form of physical contact with the mouth and nose with a carrier may harbor the virus to others. There are many cases of death reported in several countries, there has beenin particular the maximum number of 9,000. Even with the development of a cure that has been spreading further, but very late. With the help of tablets of Tamiflu and other forms of assistance, the spread of the virus may be slower.

Recent studies say that the swine flu fears are gone, at least temporarily, the United States and the northern hemisphere. However, it could rise again in coming months, need to take preventive measures to be taken into account. There may be several peaks and valleys and a flu season is no different with the H1N1 2009.

In the United States, there are still plenty of flu-like activity, but the month of October. In all age groupsH1N1 influenza from now, with the exception of the age group above 65 years or more. There is convincing evidence that H1N1 does not spread quickly from September to October 2009.

But we must not rest until I have explained both as H1N1 influenza and the other, could return in the event of the season. You can still back up in a few weeks. With the holidays with us and with people who could travel back and forth to increase this source of H1N1 again. Hugs and Familykissing while celebrating solidarity. Thus we should seek to obtain, if not already vaccinated.

Only last week 21 children have been so sick that they died in the swine flu. This brings the total to 171 deaths in children this pandemic. These are the cases of H1N1 to be confirmed. He died in April, according to the CDC, more than 500 children.

Nearly 6770 people died throughout the world since April, when the swine flubegan to explode. The recount has confirmed at less than these figures, however, since not all those who have died, tested.

The CDC still have problems, enough vaccine for everyone, though. The original plan was that about 20000000 cans per week, for now, it is regrettable to report that just the fact 11000000, packed and shipped last week.

In addition, some patients in North Carolina, are considering whether H1N1 is more resistant to Tamiflu. Thesevery sick patients with multiple health problems. These experts must be on guard to see if the H1N1 could mutate and begin to transform into a version resistant disease.

Last year, the H1N1, a strain has become resistant to Tamiflu, Relenza, but effectively combat it. Over in Britain are also looking at some strains of which are shown, resistant to Tamiflu in some patients who are seriously ill.

People have a lot to do linesreceived from the blow and in different places, only patients at high risk of the vaccine. That way, people may still have to be careful about who is ill. If you're sick, you need to stay away from people. Good hygiene practices and to prevent the spread of germs, not to speak of H1N1. The pandemic is not nailed to a distance, but shows some temporary relief.

The swine flu is surely the freedom of the press increasingly in the media. The point is deadly swine flu, is a lot of money in society. This makes sense, since he died the year 1918 100 million people of swine flu. What would be a terrible nightmare, fighting for families at this time. The state of fear must have been enormous. So the question is out for a new pandemic? Well, say some experts, yes, while someis not so sure.

History teaches us that this should be a concern. So now at this moment how bad it is H1N1 influenza? Well, let's see some statistics. Currently, flu activity is widespread in 46 states and get to see the rest of the world's largest one hundred. Site visits to the doctor leading the rise in hospital for symptoms of influenza, unfortunately, are increasing compared to previous years and the mortality of influenza.The tests were in many cases of flu and H1N1 influenza virus, the author has been completed. Thus, the H1N1 influenza a concern? I would say that the statistics are proof enough.

Personally I'll try to think if I (or my children to departure), the flight too sick to come down with a rare disease and will leave within days. What should people still think: deadly swine flu and what can I do to combat this disease? How can I keepThis also applies to my family? If you have questions like these and many others, I suggest the end the resources of the site. It will help you gain a better understanding of swine flu, and lots of information necessary for equipment to protect you and your family.
