As soon as Doris Bucher learned that a new strain of swine flu had turned up in the United States, she e-mailed the Centers for Disease Control and Prevention offering to send materials that might be useful in making a vaccine. Her colleagues at the C.D.C. had a better idea. Less than a week later, they sent a sample of the new type of virus, influenza A(H1N1), to Dr. Bucher, an associate professor of microbiology and immunology at New York Medical College. Dr. Bucher, a cheerful, fast-talking scientist who has been involved in flu research for 40 years, runs a laboratory here in Westchester County that is highly regarded for its skill at turning flu viruses into “seed stock” — a form of the virus that will grow rapidly in eggs so that drug companies can use it to make hundreds of millions of doses of vaccine. Federal health officials have not yet decided whether to call for a swine flu vaccine, but they say it is important to be ready for quick production of millions of doses. Because the virus is new, some people may need two shots to build immunity. The vaccine would probably be separate from seasonal flu vaccine, meaning a total of three shots might be recommended for certain people. Creating the seed stock is an essential first step for any vaccine. So the C.D.C. has sent samples of the new strain to about 10 other government and academic laboratories in this country, Australia, Britain, Hungary and Russia. For the past five years, Dr. Bucher’s laboratory has provided seed stock for one of the virus strains included in the seasonal flu vaccine used all over the world.

Evolutionary biology may sometimes seem like an arcane academic pursuit, but just try telling that to Gavin Smith, a virologist at Hong Kong University. For the past week, Dr. Smith and six other experts on influenza in Hong Kong, Arizona, California and Britain have been furiously analyzing the new swine flu to figure out how and when it evolved. The first viruses from the outbreak were isolated late last month, but Dr. Smith and his colleagues report on their Web site that the most recent common ancestor of the new viruses existed 6 to 11 months ago. “It could just have been going under the radar,” Dr. Smith said. The current outbreak shows how complex and mysterious the evolution of viruses is. That complexity and mystery are all the more remarkable because a virus is life reduced to its essentials. A human influenza virus, for example, is a protein shell measuring about five-millionths of an inch across, with 10 genes inside. (We have about 20,000.) Some viruses use DNA, like we do, to encode their genes. Others, like the influenza virus, use single-strand RNA. But viruses all have one thing in common, said Roland Wolkowicz, a molecular virologist at San Diego State University: they all reproduce by disintegrating and then reforming. A human flu virus, for example, latches onto a cell in the lining of the nose or throat. It manipulates a receptor on the cell so that the cell engulfs it, whereupon the virus’s genes are released from its protein shell. The host cell begins making genes and proteins that spontaneously assemble into new viruses. “No other entity out there is able to do that,” Dr. Wolkowicz said. “To me, this is what defines a virus.” The sheer number of viruses on Earth is beyond our ability to imagine. “In a small drop of water there are a billion viruses,” Dr. Wolkowicz said. Virologists have estimated that there are a million trillion trillion viruses in the world’s oceans.
