...verifiably effective treatment anywhere. In Hong Kong, clinicians are continuing to use the antiviral drug ribavirin, though tests in the U.S. have shown that it doesn't kill the coronavirus. Several kinds of vaccines are already in the works, but private companies are hesitant to spend money on a virus that could disappear soon. That means most of the research is left to the cash-strapped public sector, and progress is slow. Even the most optimistic researchers believe a vaccine will take two years to develop?assuming the virus doesn't shape-shift as readily as HIV, making it almost...
...milestone in medical history. And it was indeed a remarkable sign of how far medical research has come. But discovery often leads to greater uncertainty. "There aren't a lot of infectious diseases like this," says Dr. Ian Lipkin, a virologist at Columbia University. "This is a new virus we haven't encountered before, and we still don't understand a lot about its behavior." Scientists will eventually unravel much of this mystery. They just need more time. Here's hoping they can move as fast as the disease itself...
...should be frightened of SARS. The Hong Konger caught the disease in the devastating Amoy Gardens outbreak, and he was only discharged from the hospital on April 24. The nature of the virus is still so mysterious that nobody even knows whether or not a recovered patient like Ma can be reinfected. But with the disease on the wane in Hong Kong, SARS no longer seems so terrifying to him.

...high-risk zone, and Taiwan's statistics are looking bad. But if SARS is eventually defeated, last week may be remembered as the beginning of the end. The World Health Organization (WHO) declared the SARS outbreak contained in Vietnam, one of the first countries to be invaded by the virus, and it lifted the travel advisory on Toronto. Meanwhile, Singapore and Hong Kong have brought their rates of new infections down to levels that many residents view as acceptable. "Our hope is that we can drive this disease out of the human population and back into nature," says Dr. David...
