The World Health Organization (WHO) said that they fear if H5N1 virus researches would get publicized then it could cause millions of death.

Thinking the same aspect, the two journals which have got selected to publish the findings of those researches are in dilemma now that whether they should publish it or not.

Two separate researches were conducted, one in Netherlands and other in the Unites States. Both have been found the ways by which the H5N1 avian flu could be passed on easily among mammals.

These are not the only two institutions which have been working on to change the virus to make it more transmissible. A lot many other institutions, across the globe have been working on this concept.

The WHO said they have no problem with such researches, In fact such kind of researches should take place so one could get equipped with abundance scientific knowledge to tackle the risks being posed by the H5N1 virus.

However, they also cannot deny that generation of more dangerous forms of the virus which could spread in the world very quickly poses high risks.

"Therefore such research should be done only after all important public health risks and benefits have been identified and reviewed, and it is certain that the necessary protections to minimize the potential for negative consequences are in place", said the WHO.

The risk could however be seen as more than 350 people have lost their lives due to bird flu. Doctors said 60% of the human cases have proved to be fatal in this case. One of the nations which is said to be at the maximum risk is China. Not only because it is the world's most populated country but also because people in that country keep chickens close to them. This poses great risk of being acquired with H5N1 virus.
