Cells afflicted with SARS.Rapid and accurate diagnosis is critical for providing optimum care for patients with SARS and for helping contain the disease and protecting the community. If someone with a severe respiratory illness comes to Barnes-Jewish Hospital or St. Louis Children’s Hospital, emergency department physicians now should be able to tell whether the disease is SARS within a few hours. A team of researchers, led by Michael J. Holtzman, M.D., the Selma and Herman Seldin Professor of Medicine and professor of cell biology and physiology at Washington University School of Medicine in St. Louis, developed a diagnostic tool that allows for quick identification of whether a person with respiratory disease has SARS. They also can determine the severity of the infection, and the test can detect the SARS virus even if very few virus molecules make it into the test sample.

ChenIn the age of SARS, what the world needs is a better respirator, or breathing mask. As hospitals worldwide face major shortages of masks, Da-Ren Chen, Ph.D., assistant professor of mechanical engineering at Washington University in St. Louis, has developed material for a breathing mask using nanofibers so tiny and skinny that the entry of harmful particles as minute as viruses and bacteria is nearly impossible. Comprised of just less than two percent material, it is inexpensive to mass-produce, allowing companies a good profit opportunity.

While most of the world works to contain the spread of the virus that causes severe acute respiratory syndrome (SARS), the Genome Sequencing Center (GSC) in the School of Medicine has become part of the international effort to understand the microbe. Researchers at the GSC were called upon to sequence the new virus and poorly understood human pathogen. They completed the task in what is possibly record time — less than a week.
