The international science community is not doing enough to track the many avian influenza viruses that might cause the next pandemic, a аÄÃÅÁùºÏ²ÊÄÚÄ»ÐÅÏ¢ Davis researcher says in today's issue of the journal Nature.

Global surveillance is critical for identifying and tracking potential pandemic viruses such as highly pathogenic H5N1. But the current surveillance strategy in wild birds is piecemeal and risks missing important virus sources or subtypes, Walter Boyce writes in a commentary.

Boyce, a аÄÃÅÁùºÏ²ÊÄÚÄ»ÐÅÏ¢ Davis professor of veterinary medicine, is co-director of the $18.5 million Center for Rapid Influenza Surveillance and Research (CRISAR). The center, supported by the National Institutes of Health, is charged with tracking viruses in wild birds in the United States and Asia.

Addressing Nature's worldwide audience, Boyce says scientists must take several steps to catch avian influenza viruses before they catch us:

• Go where the H5N1 virus lives: Surveillance has focused too heavily on Europe and North America, where few wild birds are infected. To really understand the role of wild birds in spreading H5N1, more surveillance should be done in places where the virus is endemic, such as China, southeast Asia and Africa, Boyce says.
• Characterize all of the influenza viruses they collect: Currently, the narrow focus on H5N1 misses other viruses that also pose pandemic risks.
• Share samples and data more promptly: Whether caused by regulatory hurdles or researchers' concerns about intellectual property rights, a reluctance to share hampers health officials' ability to track and respond to potential pandemic viruses. Boyce recommends that the scientific community set a standard of releasing data no more than 45 days after it is generated.
