what is H5N1 and H1N1?

Pandemic is the highest level alert by WHO for a spreading disease. Earlier we had the Bird's flu, Anthrax which caused the bells to ring. But none has come closer to H1N1 since the days of smallpox  or chickenpox. H1N1 , often termed as LEVEL 1 virus causes flu like symptoms . Humans have combated level 1 virus before and have triumphed in the end. Its much lower in order or alertness to LEVEL5 (H5N1 aka Bird's flu). Though both level 1 and 5 have strikingly similar symptoms but it is only the H5N1 that is hard to fight (the order of 1->5 indicates increase in the level of disease and hence much difficult to fight).

 H1N1 can be well put to control by the use of TAMIFLU vaccine . H1N1 has a very low spreading rate in  the lungs region and hence has low fatality rate whereas H5N1 is mutating virus and hence has been able to induce fatality even after so many years.

After much of research and study finally H5N1 is at the brink of facing its end as the vaccine is nearly ready to fight against its 'basic' form.
