An experimental treatment approach called RNA interference reduced the severity of SARS infections in monkeys, U.S. researchers reported on Sunday. A tiny Maryland-based biotech company less than a year old said monkeys infected with SARS either before or after treatment became less ill than untreated monkeys.They believe their approach helps prevent the virus from infecting cells and perhaps also from spreading from cell to cell, they report in the September issue of the journal Nature Medicine.
