In contrast to the spread of West Nile Virus (West Nile Virus - Biodefense and Epidemiological Tracking: from the initial index case in New York City throughout the North American Continent during the period from 1999-2003, Severe Acute Respiratory Syndrome (SARS) has crossed international boundries within a matter of weeks.

• Bird Flu a Disaster for Poultry Production, Threatens Global Food Security: Avian influenza has caused great damage to livestock production and threatened global food security, statistics released by FAO earlier February showed that more than 450 million birds had been culled in Asia excluding China, about some 0.7 percent of the region's total inventory.  Stephen M.

• SARS, flu tough to tell apart: It's mid-January and you've got a fever, a cough and an all-over achiness. Must be the flu, right?  Then again, could it be SARS? How are you -- or your doctor -- supposed to know? ``That's a very good question and one we have no answer for right now,'' said Dr. Marguerite Erme, the Akron Health Department's disease-control medical officer.

• SARS coronavirus: a new challenge for prevention and therapy: The genes of SARS-CoV were compared with the corresponding genes of known coronaviruses of humans, pigs, cattle, dogs, cats, mice, rats, chickens, and turkeys. Each gene of SARS-CoV has only 70% or less identity with the corresponding gene of the known coronaviruses. Thus, SARS-CoV is only dis-tantly related to the known coronaviruses of humans and animals. Phylogenetic analysis suggests that SARS-CoV does not fit within any of the three groups that contain all other known coronaviruses. Holmes, J. Clin.

Politics influences outbreak investigation. It is not unusual for health authorities in affected countries to refuse to cooperate with international disease investigations out of fear of bad publicity or adverse economic impacts such as trade embargoes or loss of  tourism. - Commentary, Biodefense Brief, March 27, 2003, Center for Civilian Biodefense Strategies Clinicians' Biodefense Network
