Venn diagram of three viruses’ hit selection. All hit selection criteria were based on an inhibition rate greater than 80% on the target virus compared with an inhibition rate lower than 20% on the other viruses. In total, 19, 0, and 10 hits are specific to Marburg virus (MARV), avian influenza virus (AIV), and Lassa virus (LASV), respectively; 2, 4, and 1 hits are shared by two of the three viruses, and 36 hits are “shared hits” for three viruses.
