Remdesivir is a novel antiviral drug in the class of nucleotide analogs. It was developed by Gilead Sciences as a treatment for Ebola virus disease and Marburg virus infections, though it subsequently was found to show antiviral activity against other single stranded RNA viruses such as respiratory syncytial virus, Junin virus, Lassa fever virus, Nipah virus, Hendra virus, and the coronaviruses (including MERS and SARS viruses).
