Continuing to receive coverage is a study by UTMB researchers that found a small-molecule “broad spectrum” antiviral that will fight a host of viruses by attacking them through some feature common to an entire class of viruses. Studies of agents - including Ebola virus, Nipah virus and Rift Valley fever virus - required high- or maximum-containment facilities, and most were carried out in the Biosafety Level-3 and 4 laboratories at UTMB. “Once we started testing more and more, we figured out that it was only targeting the enveloped viruses,” said Alexander N. Freiberg, director of UTMB’s Robert E. Shope Laboratory. ScientistLive also covered the study’s findings, which are published online in the Proceedings of the National Academy of Sciences.
