Canadian scientists sequence H1N1 genome

A QUANTUM OF SCIENCE

Now we know the complete blueprint for H1N1; now what?

Today it was announced that scientists in Canada have fully sequenced the entire genome of the H1N1 influenza virus. While it's not the first viral genome to be fully sequenced, it is a landmark achievement and all the more so for having been completed in one week of around-the-clock work by scientists at Canada's National Microbiology Laboratory in Winnipeg. This is, as the saying goes, kind of a big deal.

These findings shed some intriguing light on the outbreak of H1N1 but raises even more questions, as most scientific discoveries do. For example, researchers found virtually no difference between the Mexican strains and those occurring in the US or Canada. Why, then, have so many more cases in Mexico proven fatal? The answers may not lie in the genes themselves, but rather in differences of health infrastructure and health policy. Benefits of this breakthrough include faster analysis of future strains, a better understanding of how and why H1N1 mutations or reassortments occur, and a better H1N1 vaccine - with this last being of crucial importance as major pharmaceutical companies begin the laborious process of choosing which sequences to use for their vaccines. With an improved understanding of the variations in the H1N1 genome, conserved sequences can be selected for use vaccines, resulting in a stronger, more robust protection against future infection.

Perhaps it is a little cynical, but one might consider that the timing of this announcement seems a little too convenient considering that today is the second day of the 62nd World Health Assembly, the annual meeting of the World Health Organization whose handling of the H1N1 outbreak has been criticized by many science and health professionals. Then again, maybe it is simply a case of serendipity; regardless, it is good news and that's worth remembering.

Plus, if you want to apply for the position of Viral Genome Curator at a company in Bethesda, MD, you now have one more fully-sequenced genome to add to the list.
