Humans suffer from more than a hundred different viral infections, and new viruses continue to emerge on the scene year after year. To learn about viral diseases, Dr. Luis Schang uses small molecules with drug-like properties to probe the ways viruses cause infections. He is most interested in finding common features among the many viruses that cause disease in animals or humans. With his research, Schang hopes to learn more about how viruses, despite their tiny size, make big problems in health. He’s also uncovering important information on how to use only a few drugs to fight infections with many different viruses, or even stop them before they start. In neonate infections is critical to start therapy as early as possible. Broad spectrum antivirals would allow to start treatment on first symptoms, without having to wait for any differential diagnosis.
