Restricting hospital-based services during SARS outbreak had modest impact
June 19, 2007Restrictions on the non-urgent use of hospital-based services that were imposed when a provincial health emergency was declared during the 2003 SARS (Severe Acute Respiratory Syndrome) outbreak in Toronto, Ontario, resulted in only modest reductions in overall admissions. In this study, Dr. Michael J. Schull and colleagues determined that restrictions on the non-urgent use of hospital-based services at 32 hospitals in the Greater Toronto Area resulted in a 12% decrease in admissions. The findings suggest that the ability of a health system to admit large numbers of affected patients during a future epidemic would be limited by continued high levels of hospital occupancy. For example, the 12% decrease in overall admissions seen during the SARS restrictions would only offset one-quarter of the number of additional admissions expected in an influenza pandemic in Toronto.
In a related Public Health commentary, Dr. Richard Schabas examines Canada's new Quarantine Act and argues that it would be useful in only very limited circumstances.

SARS Current Events and SARS News RSSResearchers recreate SARS virus, open door for potential defenses against future strains
Researchers at the University of North Carolina at Chapel Hill and Vanderbilt University Medical Center have synthetically reconstructed the bat variant of the SARS coronavirus (CoV) that caused the SARS epidemic of 2003.
Synthetic virus supports a bat origin for SARS
SARS - severe acute respiratory syndrome - alarmed the world five years ago as the first global pandemic of the 21st century. The coronavirus (SARS-CoV) that sickened more than 8,000 people - and killed nearly 800 of them - may have originated in bats, but the actual animal source is not known.
Study of ancient and modern plagues finds common features
In 430 B.C., a new and deadly disease-its cause remains a mystery-swept into Athens. The walled Greek city-state was teeming with citizens, soldiers and refugees of the war then raging between Athens and Sparta.
Common cold virus came from birds
A virus that causes cold-like symptoms in humans originated in birds and may have crossed the species barrier around 200 years ago, according to an article published in the December issue of the Journal of General Virology. Scientists hope their findings will help us understand how potentially deadly viruses emerge in humans.
Purdue researcher invents molecule that stops SARS
A Purdue University researcher has created a compound that prevents replication of the virus that causes SARS and could lead to a treatment for the disease.
Colds and flu cut by one-third in study of Canada's top cold fighter in vaccinated seniors
A winter free from colds and flu? Not yet. But a new study offers new evidence that Canada's top cold and flu-fighting product provides significant help.
UCSF researchers identify virus behind mysterious parrot disease
Researchers at the University of California, San Francisco, have identified a virus behind the mysterious infectious disease that has been killing parrots and exotic birds for more than 30 years.
Scientists break record by finding northernmost hydrothermal vent field
Well inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. The cluster of five vents - one towering nearly four stories in height - are venting water as hot as 570 F.
Viruses hitch a ride in the cell
Viruses can travel around cells they infect by hitching a ride on a microscopic transport system, according to new research. Cells are exposed to foreign DNA and RNA and it is understood that some of this genetic material can be integrated into the host genome. Using modern microscopic techniques, scientists have been able to see how virus DNA is transported in the cell.
Effective health messages may yield vaccine compliance among ER workers
Emergency room workers will be the first line of defense in the event of a disease pandemic and will be forced to deal with the chaos that inevitably comes with treating thousands of sick and dying. In order to protect themselves and allow them to care for the public, these first responders need to be fully prepared by getting available vaccines now.
