Early detection of highly pathogenic viral infections

The document discusses early detection of viral infections through gene expression analysis. Samples were taken from subjects infected with Lassa virus or Marburg virus over several days. Gene expression levels were measured from the samples. A subset of genes were found to have differential expression 3 days post-exposure, indicating they may serve as early markers of viral infection. Taking multiple samples over time allows analysis of changes in gene expression during the course of infection.
