Viruses have led scientists at Washington University School of Medicine in St. Louis to the discovery of a security system in host cells. Viruses that cause disease in animals beat the security system millennia ago. But now that researchers are aware of it, they can explore the possibility of bringing the system back into play in the fight against diseases such as sudden acute respiratory syndrome (SARS), West Nile virus, dengue and yellow fever.

Her talk will focus on the exotic and strange infectious diseases she has encountered throughout her medical career. The lecture is free and open to the public.

Chest x-ray of a lung affected by pneumoniaMany medical advances involve complicated new technologies or procedures. But Linda Mundy, M.D., associate professor of medicine and an infectious diseases specialist at Washington University School of Medicine in St. Louis, recently reported good results with a new pneumonia treatment that can be summed up in a single sentence: Get patients up out of bed earlier and more often, and they check out of the hospital an average of one day sooner. Mundy says the high volume of U.S. pneumonia hospitalizations could make the new treatment a potent cost-saver, but added that a second study of the approach, known as early mobilization, is needed to confirm the beneficial effects.

*Culex pipiens*, a breed of mosquito known to carry the West Nile VirusIt was a cold winter in much of the country. That’s bad news for mosquitoes, but a wet spring in much of the United States will be a benefit to the buzzing bugs. Vector control specialists have plans in place to eradicate as many mosquitoes as possible, in part to prevent another summer of the West Nile Virus. In 2002, there were more than 4,000 cases reported in the United States, and almost 300 people died. The virus also decimated bird populations. This summer Michael Diamond, M.D., Ph.D., an infectious disease specialist at Washington University School of Medicine in St. Louis, believes the situation could worsen if the virus continues to be carried by mosquitoes that bite humans more than birds. Most cases in the United States still involve livestock, and a vaccine for animals recently was approved, but no vaccine exists for humans.
