It was felt the come a few days ago. Yesterday afternoon, at the end of the meeting of its Emergency Committee, the Director of the world Organization of the health, Margaret Chan, announced to representatives of Member States raising the alert to the influenza pandemic called "swine" level 5-6 or higher on the scale of the who. After weeks of procrastination and various and often conflicting pressures, the Genevan organization therefore eventually officially declare a global pandemic, the first time in forty-one years. This means that person-to-person transmission of the virus H1N1, emerged late March to the Mexico and then to the United States, continues in different regions of the world, autonomous and now uncontrollable. The message sent to the States is the following: implement if you think necessary and as you hear him protection measures that you have prepared in the alert phase 5 (State of imminent pandemic, declared on May 1).
Speed of propagation

The H1N1 virus has already broadcast in 74 countries, affected 28.774 persons and caused 144 deaths. Many experts believe that this situation should have led the who to declare the State of pandemic for several days.
But Margaret Chan teams feared a panic effect, as the mortality of this virus is much greater than that of seasonal flu. By comparison, avian flu, H5N1 virus, is 60, but the virus is much less contagious. For a time, who has also sought to integrate the criterion of severity of the virus in its level of alert phases, before, it seems, to waive.
These days, however, the Organization had clearly suggested that she was going to level 6. The current speed of the spread of the virus in several countries of the southern hemisphere has no doubt played in the decision. In Australia, fifth country most affected in the world with all cases, 4 patients were admitted in intensive care, the who has identified a local transmission in the State of Victoria. The Chile, the number of patients has more than tripled in two days, at nearly 1,700 cases. In other regions of the world, concern mounts. Hong Kong schools and crèches were thus closed after 12 students by the virus. By Germany, 27 pupils in a school have contracted the disease.
"Second wave".
Margaret Chan has therefore sought to be reassuring, first with the representatives of the States. "The message, identified one of them, is that we are from different countries, with different situations." There is not a single specification. "Who recommends including no restriction of movement of persons, goods and services.
However, Margaret Chan called on countries to mobilize, in which regard immunization, calling laboratories, once they have completed the production of vaccine against seasonal flu (which is almost done), to "tackle quickly, full production of a pandemic vaccine against the new a(H1N1)". It has also warned that "the countries where the epidemic has reached a peak must prepare for a second wave of infection", this next fall, forecasting the movement of the virus in the world "for one to two years". The most serious apprehension of who is a mutation of this virus with a much more lethal strain as H5N1, for example. At that time, the pandemic would become for good a global danger.
