    Experts in viral diseases fear that the global spread of bird flu and the number of virus strains that are currently prevalent and cause disease reached unprecedented which increases the risk of a human pandemic levels.

   It was reported foci spread in poultry farms and wild birds among flocks in parts of Europe, Africa and Asia in the past three months. And despite the fact that most of these spots spread the strains of the virus does not pose little danger to human health, but the sheer number of different types and presence in many areas of the world at the same time increases the risk of mixing of viruses and mutations and possibly transmission to humans.

   Michael Oosterholm said a specialist in infectious diseases at the University of Minnesota, “This is a radical change in the natural history of influenza viruses,” commenting on the spread of bird flu in terms of geographical distribution of foci and strains, a situation he described as “unprecedented.”

  Health officials around the world fear that the other strain may be transmitted to humans as it did H5 strain that the one in the late nineties of the last century. Since then it caused the injury infected hundreds and hundreds of deaths among humans, but did not gain the ability to spread easily from person to person.

  The biggest fear is that you deadly strain of bird flu to mutate into a pandemic which could be easily transmitted between humans, something the world has not seen yet.

  As was normal in the previous status is limited to recording the spread of strains or three of bird flu at the same time, however, there are currently at least six strains including H5 N1 and H5 The 2 H 5 The 8 HP 7 that 8.

  According to the World Organization for Animal Health that the spots spread simultaneous among birds in the past few months raises “global concern on public health,” warned the president of the organization this week that the world “can not afford to ignore the early signs of” a possible pandemic of influenza in humans.

  The specific reasons for large numbers of unusual and continuing emergence of foci of the disease in recent months and the spread of strains despite the fact that such developments together compose the global non-proliferation mechanism of the virus was unclear.

  Said Ian MacKay, an expert on viruses at the University of Queensland in Australia that the current spread of strains means “not necessarily that there is a growing danger” to human beings.

  He told Reuters: “You have more exposure to the disease in a more farms and more frequently and more numbers in more regions of the world and therefore there must be an increase in the risk of increasing cases of human infection.”

  According to the World Health Organization, about 40 countries have reported new hotbeds for the spread of avian influenza in poultry or wild birds since November.

  He said David Nabarro, a former senior official of the organization, told Reuters in Geneva that the situation is sexy for concern. He added: “For me the threat posed by the bird flu virus is more dangerous” to public health. “”

  In light of this, they want health authorities around the world and experts of infectious disease awareness, control and vigilance to intensify development of the disease.
